DIY Webasto installation instructions

Install the fittings in the required position, in accordance with the diagram. Before installation, wet the O-rings with water. A plunger-type pump is installed BEFORE the fuel pump; it does not like dirt. Locate the exhaust gas outlet so that it cannot become clogged or damaged under any operating conditions. This is how an air heater works. The Webasto air autonomous heating system has the following design: The main element is a hermetically sealed combustion chamber. Webasto. Webasto review How the Webasto autonomous heater works. Installation in St. Petersburg. Price Webasto Starline and Webasto, autostart and control Understanding the functions of the devices You will need to connect two devices: a minitimer and the main signaling unit. This leads to the conclusion: the operation of the immobilizer, which blocks the start, does not in any way affect the ability to turn the heater on or off.

However, certain features and nuances should also be taken into account. Therefore, in my version, everything that is possible should be in the cabin.

The standard hole for the engine braid is used. Each and everyone has their own connection methods, but they all boil down to connecting the Webast and the computer using a cord or KKL adapter. An hour of operation of the unit in continuous heating mode burns from 0.1 to 0.25 liters of fuel, depending on the modification. Webasto Thermo Top Evo 5 (W-bus) Permanent emulator (-)

What are the dangers of installing Webasto yourself?

The Webasto installation process itself is not a difficult task, but the whole process depends on following the instructions, the technological map, as well as your skills in auto repair, electrical installation and installation of climate control equipment.
Even for a car enthusiast with car repair experience, installing Webasto can take up to 2 days. Deviation from the instructions and a small miscalculation can lead to voiding the warranty on the device and even lead to a car fire.

Before installing Webasto, you need to study the design of the system and options for its implementation in as much detail as possible. The stage at which many car owners make mistakes is connecting pipes to the engine. To do everything right, you need to have practical experience in carrying out such work.

The manufacturer Webasto recommends contacting certified service centers, since only specialists with extensive experience can ensure reliable and correct operation of the installed heater.

The problem of starting a cold engine in low temperatures is well known to every car owner. The power unit has difficulty starting in cold weather, and the degree of wear of loaded engine parts increases during such starts. Also, in winter, the operating comfort of vehicles is significantly reduced, since the time for warming up the internal combustion engine and the interior space to an acceptable level can be significantly increased.

To effectively solve these problems, the car can be equipped with a preheater. There are several types of such devices, with liquid engine heaters of the Webasto type having the best autonomy and performance.

In this article we intend to talk about how much Webasto costs with installation, what features and nuances are involved in installing Webasto on a gasoline engine or diesel unit, as well as how to install Webasto on a car yourself.

Read in this article

Types of engine preheaters

Based on the principle of operation, PPD for gasoline and diesel engines is divided into two main groups:

Autonomous

They use the fuel of the car itself as energy. They are more convenient, do not depend on external sources, but are more expensive. If there is no standard heater, install a ready-made installation kit at a service station.

Electrical

To operate this option, you must be connected to a 220 volt power supply. The principle of operation is the same as that of a conventional boiler, in which the coolant is heated. Circulation is carried out by gravity (the heated one rises to the top, and the cold one goes down).

Gasoline engines with fuel injection

The signs of late ignition on an injector are the same as on a carburetor engine. But in this case, you cannot independently adjust the lead angle. The fact is that the operation of the ignition and fuel injection systems is controlled by an electronic control unit. It supplies control impulses to the systems after processing signals from the camshaft position sensor and crankshaft sensor. Correction of the moment of spark formation is also carried out taking into account the signal from the knock sensor. To determine the exact cause of malfunctions, professional diagnostics are necessary. Let’s assume that testing the DPRV with a multimeter did not reveal a malfunction. But the oscilloscope can show that the signal characteristics coming from the sensor do not meet the standards. You can make earlier ignition on the injector by changing the ECU program, that is, “reflashing” the “brains”.

Use Cases

Now let's figure out how to use Webasto.

The following technologies are used for this:

1. The most financially economical option is control using a timer. The cost of this module is minimal. It is mounted inside the cabin, on the front panel.

The setup is extremely simple, you just need to synchronize the module indicators with real time, and then adjust the heating duration and startup periods. Typically, intervals range from 10 minutes to an hour.

The main inconvenience is that the parameters need to be constantly adjusted, focusing on the outside air temperature. The colder it gets, the more often the system should activate.

Watch the video for detailed instructions on setting up the 1533 mini-timer:

Video review of Webasto 1533 and MultiControl timers, pros and cons, as well as instructions for use:

2. Turn on Webasto with the button. The scheme is based on the use of a remote control that looks like an alarm key fob. The cost is higher compared to a timer, but it is compensated by ease of use.

The average distance at which the module can “catch” the remote control signal is a kilometer, which is quite enough for most operating conditions. The distance may be reduced due to physical obstacles between the receiver and transmitter (dense buildings, thick walls), or due to radio interference.

The settings allow the vehicle owner to adjust the time intervals during which the starting performance will be maintained. The remote start key fob has two-way communication with the vehicle, that is, it confirms the fact that the system responded to its command and worked.

To configure the remote control, no special actions are required. It initially operates at the required frequency. There are no difficulties in using the remote control; it is enough to protect it from dirt and direct sunlight to minimize the likelihood of damage.

Video description of Webasto control using the T91 9028761A remote control:

3. Launching Webasto from a cell phone is the most expensive method (the cost is about one and a half times higher than in the case of a remote control), but the high cost is compensated by convenience, unlimited range, resistance to failures and interference.

To implement this technology, a GSM unit is mounted on the module. How to turn on the system? It responds to a text message sent from a specific number stored in memory.

The maximum number of numbers is 5 pieces. The most modern way is control through a special application installed on a smartphone. It allows you not only to activate warm-up, but also to maintain two-way communication and monitor the current state of the engine.

Starting the heater and temperature settings

Click OK on the display, check the set temperature and power, and press the power button (middle right). The fan begins to gradually gain momentum.

If you connected the device via a battery, then do not be surprised that until the mode reaches maximum, there will be a very strong voltage drop of two or more volts. At start, as mentioned above, the current consumption reaches 10A.

Based on this, your battery should be well charged. After some time, you will hear clicks of fuel supply from the pump and a characteristic noise after turning on the ignition.

What real parameters will this Chinese heater produce at its maximum capabilities? Firstly, the temperature of the hot air, even at the farthest point of the outlet pipe, will exceed 90 degrees.

And the internal radiator grill itself heats up to 180C and higher.

At the exhaust pipe, gases will be thrown out at a temperature of 150 degrees.

At the same time, the plastic body of the stove itself does not heat above 50C in normal mode. So don't worry, nothing will melt or leak there.

With a minimum power of 1.5 kW, the stove operates almost silently, but the outlet temperature drops to 60C.

This mode is very economical and useful in late autumn or spring, when there are no severe frosts, but you still want to create a warm, cozy environment in the garage.

The heater accelerates and reaches maximum mode within 5 minutes.

There will certainly be noise from the operation of the fan and stove, but it cannot be compared with the noise from a gas gun. When a gas installation is running, it is simply impossible to talk indoors.

And with this autonomous heater you can even fall asleep in the far corner on the sofa.

But most importantly, with proper assembly and sealing, there is no smell from this heater, unlike the same gas and especially diesel guns.

The combustion chamber and air heating in the Chinese Webast are separated. Therefore, all combustion products are completely expelled through the exhaust pipe.

But if you are still afraid of getting burned, and the manufacturers’ statements do not inspire confidence in you, then for complete safety, install a CO sensor in the garage. These are also sold on Ali. More details

Is it worth installing Webasto?

So, if the car is operated in a region with frosty and long winters, is used in such conditions as a commercial vehicle, the driver wants to increase operating comfort in winter, etc., then the question regarding the installation of a pre-heater becomes especially relevant.

In the case of Webasto, the answer will be in the affirmative, even taking into account the fairly high initial cost of such a heater and its installation. On average, buying and installing Webasto will cost from 40 to 100 thousand rubles. for the device itself (depending on the type of vehicle), as well as about 15 thousand rubles. for installation.

However, such a pre-heater will allow you to start the engine in any frost, increasing the overall resource of the internal combustion engine. We also note that warming up the engine and interior with an autonomous heater before a trip is noticeably reduced, which allows us to talk about fuel economy (especially in relation to gasoline cars).

On diesel engines, installing Webasto allows you to solve the well-known problem of diesel fuel, which thickens in cold weather. It turns out that installing preheating is more or less beneficial from an economic point of view, since fuel consumption is reduced, the engine is subject to less wear, which reduces the cost of its repair.

For maximum savings, many drivers (especially owners of passenger cars and small commercial vehicles) also prefer to install this equipment themselves. In other words, you will need a Webasto kit, installation instructions, the necessary tools and a place to carry out the work (it is advisable to have a garage with a lift or pit).

How to install Webasto yourself?

Installing Webasto in the engine compartment

If there are no detailed instructions for installing a Webasto heater specifically on your car model, then the main problem will be finding a place to install the most important part of the Webasto - the boiler. The following must be taken into account:

read the Webasto installation instructions - it indicates how to correctly install the Webasto boiler - its incorrect position will lead to the device not working. You may have to make your own bracket to install the Webasto boiler;

Route the exhaust pipe of the heater in such a way as to avoid exhaust gases entering the passenger compartment as much as possible.

the device should not come into contact with moving parts of the car;
position the boiler so that it is possible to connect hoses, an exhaust pipe, and a filter to it;
hoses leading to the circulation pump should not bend, rub against moving parts and limit the operation of mechanisms. In addition, they should not be too long;
the fuel pipe must be installed so that it cannot get caught on anything when moving or fray;
Determine in advance where the timer will be installed in the cabin. Usually its small dimensions and light weight make it possible to glue it with double-sided tape;
try to route the tubes from the heater so that they can heat the fuel line - this is especially important if the Webasto runs on diesel fuel;
decide how fuel will be collected. On some cars, the manufacturer provides a place for inserting the Webasto fitting into the housing cover of the submersible fuel pump. The length of the fitting tube allows you to take fuel from the bottom of the tank;
ensure a safe supply of fuel to the heater.
Installing Webasto in front of the radiator

Often, to install the pre-heater, they use the space intended for the washer reservoir under the front bumper or fender, moving the reservoir to another location. On some cars, it is possible to “squeeze” Webasto into the engine compartment - on the panel separating the engine compartment and the interior. Having made a homemade bracket, the heater boiler can be installed using the fastening of the left engine support (mount) (gearbox). And finally, if you have decided on the layout of the heater, but the fasteners, tubes, and hoses sold with it do not allow installation, then you will have to purchase what you need yourself. For example, standard coolant hoses are often bent; in this case, it is appropriate to use plumbing pipe angles of a suitable diameter.

Selection of unit according to car parameters

When choosing a set of equipment, you need to focus on the parameters of the vehicle. For cars with an engine of up to two liters, the four-kilowatt Themo Top E is suitable. If the engine capacity is larger, then you need to take the EVO5.

Next, the selection of the governing body is carried out. Depending on your budget, you can choose one of three options. For an inexpensive car, they usually install a mini-timer with the ability to set a startup program for the next day. It is installed on the dashboard.

TermoCall 3 is used as a remote start. This is a receiver for GSM signals from phone calls or SMS. It also connects to Android applications.

The Webasto owner can remount it from one of his cars to another. The resource provided by the manufacturer is approximately 9-10 years. Therefore, car owners often transfer the unit to each car they purchase, sparing the fuel system and engine each time.

Using the system

The video instruction manual for the device will reveal many interesting points:

The fuel preheating unit must not be subjected to mechanical stress. It is worth taking care that there is no liquid or aggressive media in it.
You should not run the device in a garage where there is no forced exhaust.
If any unusual noise or odor appears, it is recommended to turn off the device. Removing the fuse will allow an emergency shutdown.
The instructions for using Webasto indicate which fuel is preferable to use, which is what you should listen to.
As a preventative measure, the device starts with a minimum power indicator when the engine is cold. The procedure is carried out once a month.
The period of continuous operation is 60 minutes.

Webasto device

Launch methods

How to turn on the autonomy is described in the instructions, but it’s not difficult to guess that there are only three ways - through a remote control in the form of a key fob, a built-in timer, or from a mobile device:

The option with a key fob will cost about 10 thousand rubles. The range is 1 km, which allows you to start warming up in advance. Pre-setting allows you to set an exact period of time, then the temperature will be maintained and provide triggers. Owners of the device note that it is more convenient to control using the remote control than setting the timer time each time. The launch will be signaled by a signal on the key fob. The timer will cost three times less

It is important to clearly synchronize the time on the timer with the real one. Two criteria are programmed - heating and start time

The maximum possible interval is 60 minutes. In the case of a telephone, a GSM unit must be installed. The signal is sent to any distance from any point. The device will respond to the received message from the phone. You can connect a maximum of five numbers. A modern application will allow you to have a complete picture of the condition of the car and device.

Setting the timer

The timer is located in the cabin, its use allows you to save fuel. Adjustable to within a minute, with three possible launches. There are several modes and a clear setting algorithm:

To set the time, use the “<” or “>” buttons.
To fix the on time, press “set” and use the forward or backward buttons to set the time.
By holding down "set" and pressing "<" or ">", you can fix the duration of work, which can be 10-60 minutes.

Remote control

Control using a remote control is more convenient for those owners who constantly park their car near the house. Programming the timer is not that difficult, but many drivers simply forget how to do it, but from the key fob you just need to press one button. The only drawback of remote control is that radio interference and power lines can become an obstacle to signal transmission.

How to install and connect a fuel pump

Let's move on to connecting the fuel pump. Spray its fastening rubber with WD40 liquid (otherwise the barrel will not fit), and pull it onto the pump.

Where the fuel pump has a terminal block for the wires, this is the outlet to the heater.

On the other side, a tube from the diesel fuel tank is connected. Attach the fuel pump to the wall at an angle of 45 degrees or strictly vertically.

In this case, air will not accumulate in it and the liquid will completely fill the entire space.

In this case, it is advisable to place the pump itself below the diesel fuel tank, and the fuel hose should not have sharp turns.

This is done so that in the event of airing (for example, opening the lid to add diesel fuel or checking the level), air can easily escape from the tube upward into the tank. Otherwise, the pump will take a very long time to pump.

They say that this pump is one of the weakest elements of the system and is the first to “fly”. Fortunately, the Chinese sell them in unlimited quantities. You can select the right model for your Webasta here.

How to enable Webasto manually?

With the GSM module it is possible to control the Webasto heater from a mobile phone.

The interior control panel is usually mounted on the instrument panel - so that it is convenient to configure Webasto from the driver’s seat. First, familiarize yourself with the control panel by studying the symbols on its buttons. To launch Webasto, find a button with an image of either a flame or a similar symbol. In any case, the image will be clear - it may be similar to the symbols of the glass heating buttons or the icons located at the standard heater control buttons (handles). Webasto is turned on by pressing this button, and the operation indicator will appear on the display. Pressing it again will turn off the heater.

It is also necessary to take into account that the device may become blocked after three unsuccessful start attempts. Try unlocking Webasto by removing the fuse from the power supply. It is also possible that the heater has already been blocked before. If the attempt to turn on Webasto from the remote control still fails, then, most likely, you will still have to turn to specialists for help. They will also tell you how to turn on Webasto correctly. The first start-up after a long period of “idleness” of the heater may take some time for the fuel system of the device to bleed. In addition, before starting, you need to make sure that there are no air pockets in the pipes - overheating of the temperature sensors will lead to an emergency shutdown. You can also turn on Webasto with the engine running, using it as an additional interior heater, or rather, to increase the air temperature

This is especially important if you have a car with a diesel engine - the “stoves” of diesel engines do not warm up well, and when idling in severe frosts, the heaters of gasoline cars stop efficiently “heating” the interior. In order to turn on Webasto without a remote control (if it is broken or missing for some reason), you will have to find a way to “bypass” the control electronics

But at the same time, you risk damaging the device, for example, by overheating it.

Step-by-step instructions for assembling a Chinese Webasto

How to assemble this heater and prepare it for operation? The first thing you need to think about is attaching a metal plate to the wall on which this stove will stand.

To do this, it is convenient to use small metal corners.

But with sufficiently thick walls, you can make a more reliable fastening with studs.

Next, before placing the stove on the plate, do not forget to thread the power cable through a special slot.

Screw the exhaust corrugated pipe with a clamp to the pipe, from the side of the hole with the aluminum radiator.

Those who have already tested this stove in operation suggest fitting the exhaust with a high-temperature sealant. A conventional clamp cannot always create such a tight connection that completely isolates the exhaust gases.

Here's a look at the results of operating such a stove without good exhaust sealing. Gases visibly escape.

When installed in a car and the pipe protruding on the street, this is not critical. But when installed inside a small garage with poor ventilation, the smell may be noticeable.

On the other side, where there is a plastic grille with a fan, air is taken in.

Professionals and the manufacturer advise taking fresh air from the street, and not from the garage.

The stove has two independent air circuits. For the first circuit, air is taken from outside, heated by a burner, after which the metal radiator heats up and the air is released along with the exhaust gases back into the street.

This air flow is needed for combustion of the mixture, and not for heating, as some are mistaken.

In the second circuit, the air inside the garage is driven. If you take air from the garage, then you will simply throw already heated warm air masses outside, thereby worsening the efficiency of the heater!

Where is the best place to place this stove and where to secure the platform? Someone, without much fuss, stuffs this thing into a standard case from a computer system unit.

At the same time, connecting it from the computer power supply. But it’s better to do everything wisely. Place it where it is easiest to remove the exhaust gases outside.

For example, you can place it near an existing ventilation grill. And if you have a potbelly stove in your garage with a pipe leading out into the street, then place the heater not far from it.

This way, the exhaust pipe can be led directly into this furnace and there will be no need to break or drill the walls.

In this case, the stove itself will heat up to 50 degrees from the gases and also release this heat into the room.

And as an option, you can install a heating radiator nearby. First lead the exhaust from the heater into it, and only then take it out.

This way, your hot exhaust gases will not be wasted, and will additionally heat up another battery in the garage.

Just be careful with sealing the joints. Use a high temperature sealant here too. It handles high temperatures calmly. Entry and exit from the radiator is done through pipes.

Some even recommend installing two radiators in order to further increase efficiency. Should not be doing that. When the heater switches to low mode, a dew point will form inside the batteries and condensation will accumulate.

You always want to leave some heat on the outlet tube that will be exposed to the outside. This outlet should never freeze.

Otherwise, at one point, the hole will become clogged with ice and gases will flow into the garage. When working well, such a pipe “smoke” like a real potbelly stove.

In addition, do not forget that according to the instructions, the outlet through the direct flow pipe should be no more than 2 meters.

Therefore, as you understand, a large number of radiator sections cannot be connected here. And repairmen of such stoves claim that for stable operation of the entire unit, the exhaust and intake pipes must be the same length.

After connecting the pipes, we move on to the fuel outlet.

It somehow needs to be screwed from the inside into a plastic 10-liter tank. To do this, you will have to drill a hole with a diameter of 8mm in the tank.

This can be done in two places. Which one depends on where your filler neck is located. But in any case, the outlet should always look down towards the floor so as not to accidentally “snatch” air.

This fuel outlet must be installed through the inside of the tank. To do this, insert the wire through the drilled hole and bring it out of the neck.

Next, screw the fuel outlet to it by threading the wire through the hole in it.

And tighten the whole thing back so that the guide end of the tube faces outward.

All that remains is to tighten the nut, which presses the sealing rubber from the inside and seals the joint.

Next, cut off a few centimeters of the rubber hose that comes with the kit and pull it onto the fuel pipe sticking out of the tank. A piece of hose is needed to put the filter on it.

Position it following the directional arrows that indicate the movement of fuel.

On top of the filter, through another piece of hose, a thin fuel supply tube is inserted. All connections are tightened with clamps.

When the outlet for diesel fuel is prepared, you can secure the tank to the wall.

At the same time, remember that for safety reasons, the tank should be located below the burner in the stove.

So that under no circumstances could fuel flow inside by gravity.

Heater installation

Equipment

Of course, you shouldn’t install full-size heaters designed for trucks, buses and special equipment yourself. But almost anyone can install a preheater (such as Webasto Termo Top E) on their passenger car with their own hands.

Installation kit

First you need to buy the device itself, as well as a special installation kit.

As a result, we should have:

Autonomous heater Webasto.
Gasoline pump.
Metal and plastic clamps for installing heating system elements.
Heater control panel with a set of wires for connecting it to the car’s electrical network (see also Why does the owner need a GAZelle wiring diagram).
Set of hoses and pipes.

Typically, no additional parts are required for installation. In some cases, you may need to purchase a bracket to place the device itself inside the car.

Installation principle

It’s worth immediately stating that describing the exact location of the best place to mount the heater or the location of wires and relays for power supply is an impossible task due to the design features of each car. The article provides recommendations based on the official requirements for installing Webasto Thermo Top (E,C,P). After reading them, you will be able to install a preheater for an engine of another brand, since the installation logic is largely identical.

As an example, we will use the Webasto Thermo Top series liquid autonomous heater. The principle of operation is autonomous heating and forced circulation of antifreeze along the coolant circuit. Fuel is used as fuel from the car’s fuel line or from the tank. If the driver wishes, it is possible to install a separate tank to power the heater. Analog and digital control is carried out by a remote control with a start time programming function. Additionally, you can connect a remote control.

What you need for installation

The complete set that you receive after purchasing Webasto Thermo Top C (system components from other manufacturers may differ):

heater - the main component of the system, responsible for heating the antifreeze;
a circulation pump that “drives” the coolant along the circuit;
a fuel metering pump that forces fuel supply is used to regulate the intensity of the system;
exhaust system (muffler, muffler corrugation for exhaust gas removal);
fuel intake;
wiring with connectors for connection and diagnostics;
mounting bracket;
fuel pipe;
mini-timer for starting and turning off the autonomous heating system.

All components can be purchased separately.

Installation options

There are several ways to “embed” a preheater into a car’s cooling system. The part of the circuit heated by the heater is painted black or red.

The most universal option (1 – internal combustion engine, 2 – interior heating radiator). The advantages of this method are faster heating of the interior. In this case, the liquid entering the engine cooling jacket has time to cool down considerably. Therefore, it will take longer for the engine to warm up.
The circuit is used for long lines (2 – check valve). It becomes possible to install the heater closer to the stove radiator to minimize heat loss.
A heater installed in this way provides better heating of the interior and minimal losses in the large coolant circulation circuit. Components: 1 – internal combustion engine, 2 – circulation pump, 3 – main radiator, 4 – heat exchanger, 5 – antifreeze expansion tank, 6 – engine thermostat, 7 – check valve, 8 – heater thermostat.
The diagram presented in Fig. 7, is best suited for quickly warming up the engine (the legend corresponds to Fig. 6).

Diesel and gasoline

The difference in the fuel used for operation makes adjustments not only to the design of the heater, but also determines the nuances of the installation. Unlike Otto cycle injection internal combustion engines, only a few diesel engines are equipped with a booster section in the fuel tank (analogous to a gas pump). Sometimes in the glass located in the pump tank there are unused holes closed with plugs. In this case, you don’t even have to drill a glass to install the Webasto power line. As an adapter, you must use the fuel intake supplied with the heater. This method of installation in a car with no “return” and an installed check valve in the tank is the only possible one (the fuel intake will have to be “embedded” directly into the tank).

Fuel supply

Experts strongly discourage the implementation of fuel intake from the engine compartment (especially on gasoline internal combustion engines). Excessive temperature rise causes fuel to evaporate and form gas bubbles.

a fine filter must be installed in front of the engine heater fuel pump;
The pump must be placed in a cool place. It is advisable that the temperature during operation does not exceed +20ºС;
the length from the fuel tank to the pump should not exceed 1.2 m; from the fuel pump to the heater - no more than 5.8 m;
All connections of fuel lines are crimped with clamps. The hoses themselves can be secured with ties;
markings on the pump indicate the direction of fluid circulation;
For many preheaters, there is a recommended value for the internal diameter of the fuel line.

Information about autonomous heating

Ways to warm up a car

To ensure a comfortable microclimate in the car interior, car heaters are most often used. However, they have a significant drawback - they function only when the car engine is in operating mode.

However, this is not always possible, and therefore in some situations the driver has to freeze, complaining about the wrong clothes or shoes.

An electric heater can be an alternative to a stove, but in this case there are nuances. And the most important thing is that the supply of electricity in a car is not endless, and therefore it is not always possible to spend battery power on heating.

A familiar situation, isn't it?

Autonomous car heaters are the way out of this situation. Of course, the price of such a device is much higher than that of a standard stove, but there are also plenty of benefits from its operation.

Who will benefit from the heater?

What are these benefits?

Firstly, the autonomous heater creates a comfortable temperature in the car cabin immediately after switching on. If with a stove we would hear from the driver the usual “Be patient, now we’ll start and warm up,” then in the case of an autonomous heat generator we won’t have to freeze.

Installing the device in the bus

Secondly, the use of this device provides pre-heating of the engine. Thanks to this, even in severe frost the car starts very quickly, and engine life is significantly saved.
It is also worth mentioning such advantages as maintaining the temperature in the car during long-term parking (truck drivers and those waiting in lines at customs will appreciate it), fast heating of windows, protecting them from freezing and fogging, etc.

Based on these advantages, heating devices from Webasto can be recommended:

For those who do not like to freeze inside the car, or for families who often carry small children in the car.
For those who stand in traffic jams, queues, etc. for a long time. First of all, these are taxi drivers, couriers, truck drivers, special equipment drivers, etc.
And also for those who are trying to reduce wear on their car’s engine and maximize its efficiency.

Connection diagrams

This will be reasonable, since the technicians at the station have extensive experience and will fulfill all the requirements of the technical regulations for installing the device. Therefore, its cost is quite high.

If the vehicle has a check valve on the return line to the tank, then fuel cannot be drawn from the return line. Helpful advice: to increase the efficiency of the heater, it should be located as close as possible to the cylinder block. We bring into the engine compartment a line with connectors for the heater itself and both power wires.

The line to the minitimer goes into the salon.

After receiving the command, the module’s task is to activate the heater. The timer is also connected according to this scheme. Some links: - Already an old resource, but you can read various interesting things about past models of heaters, experience, diagrams, links. The length of the fuel line should be as short as possible.

We recommend: Laying 0 4 kV cable in the ground

We turn off the engine. For those who stand in traffic jams, queues, etc. for a long time. This will be reasonable, since the technicians at the station have extensive experience and will fulfill all the requirements of the technical regulations for installing the device.

Standard heaters The Webasto heater warms up the engine quickly and efficiently. The most important provisions in this case are the following: Fuel lines must be designed in such a way that the car tilts, engine movements, etc. We set the time on the mini-timer. Wires from additional outputs can go to standard car alarm connection points. This will be reasonable, since the technicians at the station have extensive experience and will fulfill all the requirements of the technical regulations for installing the device.

Description and purpose of the Webasto autonomous heater

Now the work affects the standard cooling system. The connection of the heater to the cooling circuit must be made into the supply pipe of the vehicle's heat exchanger.

The water heater is connected to the vehicle's cooling system, fuel and electrical systems of the vehicle. In addition, it is necessary to organize good lighting, including using a portable lamp. In online publications, only a short abstract with a link to the original article is allowed. After such a start, you need to let the engine run for XX minutes. Do-it-yourself Webasto installation

Webasto installation location and options

The place for installing the heater is chosen by the installer himself. Of course, there are installation instructions, and maybe you can find them in the public domain, then the task will be much easier. All you need to do is just follow the instructions.

When installing, you must adhere to the following parameters:

Maintain the correct orientation of the heater
Place below the antifreeze level in the expansion tank.
Maintaining a safe distance from the exhaust system (exhaust)

What orientation of the heater does Webasto allow? It’s simple, the most important thing is that the antifreeze outlet from the boiler is at the top. Below is a photo with options for the location of the heater:

The antifreeze output is designated “OUT”

Errors and their elimination

All the reasons why the Webasto preheater malfunctions can be divided into four types. Codes that the electronic control unit was unable to store can be resolved by checking the fuel supply. Then only individual components or the heater itself are replaced. If there are fixed failures, then you need to look at the type of problem in memory. In the electronic control unit, you can use the error code to identify why Webasto does not start and replace the problem components.

A list of error codes can be found in the instructions. For example, 010 is too low voltage. And 047 is a short circuit in the fuel pump of the autonomous system. If the built-in Webasto diagnostic system was unable to identify the failed unit, it is necessary to check the peripheral components of the mechanism.

Detailed information about why Webasto does not start can be found out using diagnostics using a computer. With the help of the program, we will find out exactly everything about the error and receive detailed information on how to fix it. Once the fault has been resolved, the code must be reset using diagnostic software. Otherwise the unit will not start.

How to use Webasto

You can appreciate the benefits of a preheater only if you use it, but before that you need to learn how to use it. Operating the device is quite simple, but to master it you need to know some features.

How to launch Webasto

By default, the device is set to winter mode. If you plan to use it, the standard heater is set to the “warm” position. With a three-stage fan, select the first division, and with a four-stage fan, select the second. If a malfunction occurs, the system is locked by the electronic locking function. The device is started using the Telestart remote system or using a timer. You should not turn on Webasto several times with a total usage time of more than 1 hour, as this will drain the battery.

Launch Webasto from your phone

The best option for controlling the device is to start from your phone. To do this, you use a separately connected ThermoCall GPS unit (module with antenna), which costs about 14 thousand rubles, and allows you to control Webasto functions from your mobile phone by sending an SMS message to the number assigned to the device. The module allows you to control it from five independent phone numbers - this is convenient if the car is used by several family members. Webasto applications have also been developed for control from a smartphone and tablet, which receive feedback with temperature data and alarm activation.

How to set the time on Webasto

Setting the time is done by holding the “set” button while simultaneously pressing the “forward” or “backward” button, after which “set” must be released. The current time will be displayed with the corresponding symbol flashing. The setting itself is carried out using the “forward” or “backward” buttons, and the set time will be saved by pressing “set” or after the screen goes out.

Webasto control panel

The purpose of the device is to turn the device on and off while being up to 1 km away from it, and to set the duration of its operation. The remote control will be convenient for those drivers who store their car near their place of residence. Its use is more convenient than regular programming of a mini-timer, especially since many people forget to do this, and the remote control turns on the heating by simply pressing a button. The weakness of this control method is that obstacles, radio interference and power lines reduce the range of the remote control, which is indicated by an indicator showing the signal strength.

Setting the Webasto timer

This control option is the cheapest. The timer is placed in the cabin on the front panel. With its help, you can set the moment of switching on at any time with an accuracy of 1 minute. and up to three switching points, of which only one can work. Webasto operating modes can be configured using a timer as follows:

Manual activation - with the power button, the display will display the heating operation indicator and the time until the end of operation;
Automatic switching on – when pre-setting the switching moment with the display of the heating or ventilation program number;
Switching off – by pressing the switch off button or when the program time ends, the display goes off;
Display the time by pressing the “ ” buttons. When the heater is running, the time until the end of operation is visible;
Setting the moment of switching on. Press “set”, then within 10 seconds. use the “forward” or “backward” buttons to set the on time;
Erasing a program – short press “set”;
Selecting a program – press “set” for 10 seconds. until the number of the required program appears on the screen;
Setting the operating duration is done by pressing and holding “set”, and additionally pressing “ ”, while the current time is displayed on the screen with the 5th symbol flashing. Press and hold “set” again, and additionally press “ ”, the operating mode and duration (flashing icons 4 and 7) specified by the corresponding program will be displayed. Using the “ ” buttons, you can set the required operating time, which is saved with the “set” button or after the display goes out;
The remaining operating time can be adjusted in the range from 10 to 60 minutes. by pressing the " " buttons.

Setting the climate control on the heater

The heater has an automatic mode or, as many call it, climate control. With it, the device operates and is controlled not according to the maximum set power, but based on the ambient and preset temperature.

To start this mode, you must press the top two buttons simultaneously.

After this, the temperature reading will appear. Use the up and down buttons to set the desired value. How does Webasta work in this mode?

For example, you set 19C on the display, and when the set temperature is reached in the garage, the heater will automatically maintain this parameter, periodically reducing or increasing the speed and exhaust temperature. This is a direct fuel saving for you.

To set the date and time on the device, press the top button with an asterisk and use the right buttons to switch the numbers (hours and minutes).

Why is this necessary? And then, in this way you can program the time interval of operation and turn on the device in your absence. For example, you planned to have your car repaired tomorrow after 17.00.

Set the heater to turn on at 15.00 and come at five o’clock in the evening to a heated and warm room, where you can calmly do the repairs, rather than spend more than half an hour lighting the potbelly stove.

To set the timer mode:

press the star key

Press OK several times so that the alarm icon appears on the display screen

Initially, the inscription OF will light up - disabled.

Switch the device to ON mode by pressing the up arrow button.

After that it's OK. Your numbers will start blinking. Do everything as before until the desired turn-on time appears.

After setting the hours and minutes, the alarm clock and blinking numbers are displayed again. This will be the shutdown time setting. The order here is the same.

Upon completion of such programming, the stove will start itself at a certain time and warm up the garage without your participation. To reset the settings, press the star button again and switch the alarm mode from the ON position to the OF position.

Connection to the engine cooling system

The basic rule: the connection is made into the break in the hose from the engine block to the stove. How to define it? It’s very simple - with the engine running, turn on the heater fan to maximum airflow and set the temperature to maximum. Next, you need to feel the hoses of the stove, the one that is hotter is the outlet from the block to the stove. The second hose will be simply warm - this is the outlet from the stove to the engine.

Why do you need to connect this way?

An air lock may form in the stove and then the water pump of the heater will run “idle”, and as a result the heater will overheat. When connecting “from the block to the stove” you avoid air locks, because the engine is designed and installed to prevent this

Of course, it is very important to monitor the antifreeze level

You get the following diagram: you cut the hose “from the block to the stove” in one place. Connect the heater into the gap, observing the position of the pump and the mark on the heater itself.

Fuel pumping

Before the very first start, it is necessary to pump the fuel. To do this, simultaneously press the two lower buttons - OK and down arrow.

The words “H” and “OF” will light up on your display.

Switch to ON.

After this, the pump starts in a jerky manner with clicks. The corresponding icon is displayed on the screen.

To turn off pumping, set everything to OF mode by pressing the down arrow. The first step when pumping is to fill the filter.

Eventually the liquid in the tube should reach the end of the fuel hose.

Pull it and clamp it with a clamp at the corresponding inlet into the stove.

Upon completion of pumping, we proceed to the first launch.

Connecting Webasto to climate control

To connect, we will need: a diode bridge (you can solder it yourself, or you can purchase a ready-made one), copper wires with a cross-section of 2.5 - 4 mm. (different colors), fuse holder, terminals.

Disconnect the car's power supply from the battery.
Remove the climate control control unit.
From fuse F5 of the heater control unit, through a diode group and a fuse, we connect to the open circuit of the engine power supply and climate control power supply. In such a way that when the relay is activated, power is supplied from Webasto to the climate control unit, through fuse F4, F2 to pin 30 of the vehicle power bus.
Now you need to get the fuse box, find the fuses for the heater fan and connect the wires to them from contacts 87A and 30 from the heater relay. These wires are needed to supply voltage from the heater to the stove fan. The voltage here is high, so you will need a large cross-section of wire and good contact with terminals or soldering.
After connecting all nodes, we check. We turn on the Webasto with the ignition off and observe that when the temperature reaches 40°C, the stove fan turns on.
If everything works correctly, we check the tightness and insulation of the contacts and reassemble everything in the reverse order.

Setting up the control unit and connecting power

Let's move on to connecting the control unit and power wires. Attach the plastic display pad to a convenient place with screws.

At the top of the display is a sensor that measures the current temperature in the garage. Be careful not to damage it or cover it with anything.

Otherwise, you will not be able to get the device to work correctly. Connect the wires from the control box to the pump and heater through special contact chips. It's difficult to confuse them.

The thickest is the power wire, which must be connected either from a battery or from a 12V power supply.

Similar ones are widely used for LED strips.

The current consumption of the Chinese Webasta heater at startup reaches 10A. Therefore, it is better to take a powerful unit with a reserve of 250-300W.

If you don’t want to buy a separate unit, then use a charger connected via the battery and the network.

This thing will never be useless in any garage.

More details

Is it possible to connect this Webast only from the power supply, without a battery? No, not recommended. It is advisable to use them in parallel connection.

Otherwise, if the light suddenly goes out, the heater will simply burn itself out from the inside. In normal mode, when you turn it off with the button, it first cools all its internals, extinguishes the flame, and only then completely and correctly turns off the fan and turns itself off.

Therefore, it is necessary to have a battery if you want the device to work for a long time and properly.

The main question that interests many is how long will the battery last? As real tests have shown, for a 90-amp battery, the heater lasts for 10-12 hours of continuous operation. Well, in general, roughly assume a maximum current of 10 A/h.

After applying voltage and pressing the power button, the display lights up.

What functions does it have, how to manage it? Press the "OK" button - the temperature is displayed.

Press “OK” again - the power set on the heater is displayed.

It can be reduced or increased using the up and down buttons on the right side.

Next comes the current voltage of the on-board network from the battery or power supply.

This is followed by error codes.

You can see what they mean from the table below.

After the codes, the time is displayed and all functions are repeated again.

Gazelle Next is one of the leaders in sales among commercial vehicles.

This car in the Comfort 2 configuration is equipped with a Webasto preheater. In the basic and Comfort 1 configurations, Webasto on the Gazelle Next is an additional option. In our climate, this option is very useful.

Webasto control on gazelle next

Using the Webasto pre-launch device on the Gazelle Next has a small nuance. To control the heater, you can use a timer (or a remote control device) or a button on the panel (indicated by number 1 in the illustration below).

When controlled by a button on the panel, the heater will operate in preheater mode, and when controlled using a timer or remote control device, it will operate in preheater mode.

Preheater mode only works when the engine is running

Unlock Webasto

Usually, with proper operation, problems with the heater do not arise, but in some emergency situation the Webasto may become blocked. For example, if the heater burner flame goes out due to freezing of diesel fuel in the supply system, the device will be automatically blocked.

Therefore, if next Webasto does not work on a gazelle even after eliminating the cause of the emergency situation, then most likely it is simply blocked.

You can unlock it by turning off the power or using a special program. You can de-energize the Webasto by removing the terminal from the battery or removing the required fuse (all actions are performed with the heater on).

Instructions for using Webasto on Gazelle Next are usually issued when purchasing a car.

If there are no instructions, you can download it from the websites of Webasto representatives.

Webasto operating instructions

The heater itself should not pose a fire hazard, despite the fact that its operating principle is based on burning fuel. This requirement is quite feasible if you maintain the distance between all parts of the heater. If your car is an M2 or M3 class, it is not recommended to install the heater in the passenger compartment.

Particular attention should be paid to the installation of the fuel supply system. If the car runs on liquid fuel, then you should ensure that the filler pipe is equipped with a locking cap

Speaking about a similar operating system, I would like to say that all diesel heaters are similar, just like all gasoline heaters are similar to each other. Among diesel engines, the most popular model is the Evo 5500 12V. Among gasoline heaters, the popular models are Thermo 90ST, Thermo Top E and Webasto Thermo Top C.

It is worth noting that from time to time it is necessary to carry out maintenance procedures and monitor the health of the heater. Today, you can undergo a technical inspection and maintenance procedure at any auto repair shop.

17 tips from an expert

To know

How Webasto works

The heater is started by a program timer located in the cabin, or by the remote control with which the device is equipped. The device operates as follows:

Fuel from the tank enters the combustion chamber of the heater and heats the coolant of the heat exchanger.
The circulation pump pumps heated liquid through the engine cooling circuit, due to which the engine itself and the interior heating radiator warm up.

The Webasto operation process is fully automated - its start and stop is subject to timer commands, engine and environmental temperature sensors. This solution made it possible to minimize fuel consumption to 0.5 l/h, and reduce the warm-up speed in a passenger car to 15 minutes at an outside temperature of -20°C.

Design and operating principle

Structurally, Webasto is a compact device, weighing several kilograms. It is located under the hood of the vehicle, the power system is connected to the car, and the cooling circuit is connected to the cooling circuit of the power plant.

An electronic module connected to the on-board vehicle network is responsible for control.

The operating principle of the device can be described as follows:

The supply of fuel from the tank to the heater’s own combustion chambers is activated. This allows you to increase the temperature of the coolant inside the heat exchanger.
The circulation pump is activated, thanks to which the heated liquid flows to the motor. It heats both the engine itself and the radiator serving the interior.

The workflow can be fully automated so that the process is activated by sensors that respond to a decrease in ambient temperature or by a timer.

In terms of fuel consumption, the system is economical , the average consumption is 0.5 liters per hour. Fully warming up the car at this flow rate and air temperature of minus 20 degrees takes only a quarter of an hour.
