Features of replacing the heater radiator in a Chevrolet Niva with and without air conditioning
The heating system of any vehicle has its own components that ensure the full functioning of the entire device.
The stove radiator plays an important role in the operation of the system. Situations arise when the device fails and stops working. To fix any serious problem, you will have to dismantle the unit. The radiator is located according to a special design. The article will tell you in what cases the radiator requires replacement and how to replace it yourself.
Typical radiator malfunctions
There are two main radiator malfunctions:
- Clogged grille and radiator tubes.
- Radiator leakage.
Since the Niva is often operated in difficult road conditions, the likelihood of contamination of the grille from dusty outside air is very high. Clogging of the cells reduces the heat transfer area of the radiator, and as a result leads to a decrease in the heat released from the air ducts into the passenger compartment. In such cases, the stove radiator is dismantled and washed under high pressure.
Where is the heater radiator located on the Chevrolet Niva?
The heating system of a car consists of a number of elements, without which its normal functioning is impossible. One of these is the stove radiator. Sometimes problems occur with the heat exchanger, to eliminate which it is necessary to dismantle the unit. The radiator is located in the cabin behind the heater control unit.
Body interior heating system: 1 — ventilation duct; 2 — air duct for heating the windshield; 3 - intermediate body; 4 - intermediate air duct; 5 — air intake filter housing; 6 — heating system fan; 7 — central cabin ventilation nozzle; 8 — facing of the control lever panel;
The final stage of work
The tubes are mounted in the reverse order, the clamps are attached, and the expansion tank bolt is screwed on. The barrel is filled with antifreeze and after several days of operating the machine, the liquid level in the tank is monitored. The absence of smudges, odor and warm comfort in the cabin will be a reason to replace the glove box.
Comfort in the interior of any car during the cold season is largely determined by the efficiency and serviceability of the heating system. Heating problems most often arise due to a faulty stove radiator.
Fan replacement
So, if there is an urgent need to replace the stove motor, we recommend that you hurry with the repairs without waiting for frost. Believe me, driving in a vehicle in which the heating system does not function is quite uncomfortable. In addition, in severe frosts such trips are still extremely unsafe, since the lack of heat does not allow the ice concentrated on the windows to thaw. Icy windows limit the driver's visibility of the roadway and, accordingly, provoke emergency situations.
So, pick up a new fan and check the quality of rotation of the blades. If you have not purchased it yet, we recommend that you give preference to a model with bearings, of course, if the auto store offers you an expanded range of heaters suitable for your Chevrolet Niva.
Improvement No. 2. Increasing fan performance
I also slightly increased the efficiency of the standard heater fan. The fact is that the gap between the fan blades and the diffuser is about 3 mm, and the width of the diffuser is no more than 15 mm, while the width of the fan blades is more than 30 mm. Therefore, some of the air leaks back between the blades and the diffuser, preventing a large pressure difference from being created between the suction area and the discharge area.
To eliminate these shortcomings, I reduced the gap between the diffuser blades and lengthened the diffuser. I solved these problems by cutting out a strip 30 mm wide and equal to the circumference of the diffuser from an old plastic fender liner 1 mm thick. I inserted the bent end-to-end ring from this strip tightly into the diffuser and “sewed” it to the diffuser with a thin wire through the drilled holes, so that the fan blades did not cling to the strip or wire. Against the blowing windows, the width of the strip is trimmed to 20-25 mm.
According to my estimates, the efficiency of the fan increases by 10-15%, so you don’t have to bother with this problem.
How to replace a heater radiator on a Chevrolet Niva with air conditioning (what are the differences)
Replacing the radiator of a Niva Chevrolet stove with air conditioning is carried out by changing the evaporator. To simplify the furnace reassembly process, it is advisable to mark all connectors using a special marker. After removing the fan, begin dismantling the regulator.
