Lada. How to change the radiator, removal and installation on a VAZ 2114-2115.

For greater convenience and comfort of both the driver and passengers, VAZ cars (and, perhaps, almost all modern cars) are equipped with a heating system. Not the least role in it is played by the DaAZ 2114 radiator, which is responsible for transferring heat directly to the car interior. We will talk about how to find out whether the radiator is working properly, as well as what to do if it breaks down in today’s article.

Radiator DaAZ 2114

Tools required for repairs

If you want to do the repairs yourself, you need to prepare the following tools:

• keys for 8 and 10;
• screwdrivers;
• heads for 8 and 10;
• pliers;
• container for draining antifreeze;
• jack;
• sealant;
• rags.

Independent work is completely justified, since as of March 24, 2019, the average price for replacing a cooling radiator for a VAZ 2114 and other models is 2.2 thousand rubles. Which will more than double costs.

Why the OS does not work

The cooling system most often stops working due to improper operation of the thermostat. You can't do anything other than replace it.

If you don’t know which cooling radiator is best to choose for the VAZ 2114, look at the existing one. Buy an analogue from the manufacturer, or purchase a device with the closest characteristics.

The fourteenth model is equipped with an aluminum radiator with two additional tanks. The radiator design includes:

• Radiator;
• Upper tank with pipes;
• Bottom tank with pipes.

Order of Operations

If the car has a low seating position or the coolant drain tank is large, work should begin by lifting the car with a jack. The radiator is installed on the TV along with fog and regular headlights. Work should only begin with a cold engine. If the engine is hot, be sure to wait until it cools down.

Now you can get started:

1. After removing the plug from the expansion barrel, the working fluid is drained into a container. It is necessary to drain all the antifreeze that is in the cooling system.
2. Now you need to dismantle the filter.
3. The radiator must be removed together with the electric fan. To do this, you need to disconnect the power supply to the cooler. Now you need to unscrew the pressure plate and remove it.
4. Now you need to remove the inlet and outlet hoses from the pipes. To do this, loosen the fastener clamp.

The radiator with fan is tilted towards the engine and removed. Attention! Before pulling out the fan, you need to disconnect the wires. They are usually located at the bottom of the device. This is necessary in order to maintain the functionality of the wiring.

• Now you need to disconnect the fan from the radiator. To do this, use a 10mm wrench to unscrew 2 nuts. The fan must be removed along with the casing.
• Installation of the radiator is carried out in the reverse order to that described above. It begins with switching the new node and the fan. Important! Before replacing, make sure that there are 2 rubber cushions. If they are missing, install new ones in the crossmember holes. If they are in place, then the installation of the new unit is carried out on them.

1. Unscrew the two 10mm nuts on the engine shield. (photo at the beginning of the article)
2. If you are changing both the faucet and the radiator, then remove the faucet along with the pipes after disconnecting them from the radiator

1. Remove the latch and cable

Stove valve control cable.

1. We insert mounting bolts into the new stove faucet, and also mount the pipes in the position in which they were on the old faucet and tighten the clamps so that there is no pain later.

A small life hack. After installing the bolts, drop a little superglue on the seats, so they will not jump out when installing the faucet in place.

1. Before installing the stove tap in place, we connect the cable and check that the tap opens and closes completely when changing the position of the manual heat-cold switch.
2. If everything is normal, we install the faucet in place, connect the pipes and fill in antifreeze and enjoy the hot air from the heater even when idling.

Just for fun, I measured the air temperature at the outlet of the vent on the center console; with the engines fully warmed up and the outside air temperature +12, the thermometer showed +43 degrees in the second position of the fan.

Everything is very simple, it took about 1.5 hours to replace the radiator, and 30 minutes to replace the faucet. This procedure is easy to perform with your own hands, in a regular garage, even without an assistant.

Good luck on the roads. Not a nail. Not a rod!

Let's summarize

In general, repairs are quite accessible for doing it yourself, but you need to immediately prepare for a significant time investment. Work can last for 2-6 hours. When replacing the radiator, it is necessary to change the coolant. Work with 8-valve and 16-valve engines is carried out in the same way. If the car has air conditioning, you will have to remove and install it during the repair, but not on all models. It is advisable to replace the bushings at the same time. The work is completed by checking the functionality of the engine and the condition of the coolant. Namely, whether it is boiling.

Design and operation diagram of the interior heater of the VAZ 2114

During the cold season, the interior of the VAZ 2114 car is heated using a heater or stove. The basis of the stove is the radiator. Using a system of air ducts and dampers, the heat from it is directed to different areas of the cabin. This creates a microclimate that prevents the glass from freezing and provides comfortable conditions for the driver.

The stove in a VAZ 2114 car works on a fairly simple principle.

The heater operation scheme is quite simple. The heat source is a running engine, for cooling of which a special liquid is used - antifreeze. When the antifreeze moves in a vicious circle, heat is transferred from the hot motor to the cooling zones. There are two such zones in a passenger car - these are the radiators of the engine cooling system and the heater. Hot antifreeze transfers heat to cold air, which circulates through the radiator honeycombs using fans. Thus, the antifreeze cools down and returns to the engine, where it heats up again. This process must be continuous while the engine is running.

Step-by-step replacement process

1. Open the hood and unscrew the two bolts securing the filter housing to the front panel. Ten head bolts.
2. Press the latch and disconnect the mass air flow sensor power connector.
3. Lift the filter housing and move it to the side.

Changing the VAZ 2114 cooling radiator with your own hands

VAZ 2114 is considered one of the most striking examples of success of the domestic automobile industry. This model is a modified version of the VAZ 2109 and differs from it in the design of the front part of the body, updated headlights and hood, radiator grille design, as well as plastic moldings and spoilers. However, as it became known, the car is susceptible to radiator failures, which can lead to overheating, and as a result, to engine failure.

Radiator repair

In some cases, the radiator can be repaired, so you don’t have to buy a new spare part.

Mostly repair work consists of eliminating leaks that have arisen as a result of defects, cracks and holes.

Most often, liquid leaks at the junction of plastic and metal parts. If there is a small leak, you can pour a special liquid with a coolant mixture inside the radiator. Thanks to its special composition, this product will seal the defects that caused the leak. If the damage is serious, repairs will no longer save the situation; you will still have to replace the radiator.

To check the tightness of the radiator, you can conduct a simple experiment at home.

1. Fill the bathroom with enough water to submerge the radiator.
2. Close all pipe openings tightly.
3. Lower the radiator under water about 30-50 centimeters. Apply a pressure of 0.2 MPa to it.
4. Watch what happens. If bubbles appear, the system is not sealed and needs to be repaired or replaced.

Do not even try to repair the radiator after side or frontal impacts in an accident. In such situations, he suffers first of all, and no clogging liquids will help you.

Replacing the cooling radiator

It is worth noting that the radiator from 2114 is also suitable for other representatives of the VAZ model range. As you know, VAZ’s developments are universal, so it is not surprising that not only cooling system parts, but also other spare parts from earlier and later models of this brand will ideally fit the 2114.

As one of the main parts of the cooling system that is in constant operation, the radiator may require replacement because it becomes clogged with debris or suffers mechanical damage. In addition, the coolant must be replaced in a timely manner, otherwise it will corrode it from the inside, which will undoubtedly lead to breakdown.

Radiator selection

The most popular radiators are aluminum, and this is not surprising, because they cost much less than copper (or brass), and they are much easier to find on sale. Based on the type of cooling grille, they can all be divided into two large groups: prefabricated (inside of which there are sets of plates with tubes fixed in them through which coolant circulates) and non-prefabricated (a special corrugated tape is installed inside them).

Aluminum

At the same time, all aluminum radiators (which include the DAAZ heater radiator for the VAZ 2114) have both significant advantages and certain disadvantages.

The first include:

• low cost, especially for prefabricated models;
• high thermal conductivity, ensuring rapid heating;
• light weight;
• high structural rigidity, making them quite resistant to external influences.

As negative points it is worth noting:

• rapid cooling (again due to high thermal conductivity) - when the engine is turned off, the car cools down quickly;
• short service life (compared to copper models);
• low maintainability (soldering aluminum in garage conditions is extremely difficult).

It is also very important to note that it is impossible to use ordinary water as a coolant (as domestic motorists sometimes do) with an aluminum radiator installed, since it will quickly cause corrosion.

Copper

Speaking about copper radiators, it is worth saying that according to the principle of their design, they are close to aluminum non-assembled radiators, but at the same time they have much better heat transfer.

Their advantages include:

• better heat retention, slow cooling;
• greater efficiency due to higher heat transfer;
• high maintainability (copper can be soldered even in “field” conditions);
• long service life.

Copper radiator VAZ 2114

But, despite such important advantages, they also have the following serious disadvantages:

• high cost (in most cases it is twice the cost of aluminum models);
• very long heating (after turning on the stove, the interior will not warm up soon);
• low efficiency when the engine operates at low speeds.

It is because of these shortcomings that copper radiator models are considered obsolete from a moral point of view, and increasingly even large manufacturers are installing aluminum devices on their cars.

That is why, if you are faced with the problem of choosing whether to take a radiator made of copper or aluminum, it is better to give preference to the latter option. At the same time, not only the material itself is important, but also the overall quality of workmanship.

Refilling a new radiator

Finally, “Tosol” or antifreeze should be poured into the expansion tank of the new radiator. Basically, approximately 5-8 liters of liquid are poured into the new cooling system to cool the engine. After filling with antifreeze, the car must be started and left running for a few minutes so that the thermostat opens and the antifreeze goes into the engine cooling system. Replacing the 2114 radiator, like any other VAZ model, should be carried out in a warm room or in the summer season.

The main causes of radiator failure

Engine cooling radiator

Let's look at the main reasons for radiator failure on a VAZ-2114:

• mechanical damage (bounced stones or large debris on the road);
• deposits inside the tubes in the form of scale or rust, dirt;
• damage as a result of an accident.

How to prevent engine overheating?

To prevent engine overheating, it is necessary to constantly monitor the amount of coolant in the expansion tank, the operation of the thermostat and the condition of the radiator itself.

This is what a newly installed engine cooling radiator looks like. You need to make sure it is clean and blow it out regularly.

The appearance of traces of coolant on the asphalt after a short or long period of parking, as well as wet marks on the radiator itself, is a signal to check the radiator for leaks and possibly subsequently replace it.

Engine overheating

Coolant leaks can be caused by small cracks or loose connections. In such cases, it is possible to repair the radiator even without dismantling it. When repair is not possible, the only option is replacement.
