Replacement of the radiator of the stove "Priora": with and without air conditioning

Before the onset of cold season it is necessarycheck the car heater for leaks, the serviceability of the elements and the integrity of the heat exchanger. This will allow you to prepare the car in time and make your stay comfortable. Replacement of the radiator of the stove "Priora" is carried out with any cracks and damages, as this element is not subject to repair.

Symptoms of problems

On the car VAZ-2170 installed heaterLiquid type, which interacts with the cooling system of the power plant. The coolant circulates regularly through the heat exchanger, which is a factor affecting the corrosion and wear of the part.

Replacement of the radiator of the stove "Priora" may be necessary if there are following signs:

• The heater stopped warming normally.
• The level of coolant has noticeably dropped.

First, check the heating elementvisually. It is necessary to disassemble part of the node and inspect the radiator. If traces of rust or calcareous deposits are visible, the heat exchanger is likely to flow. Preliminary it is necessary to investigate feeding and connecting hoses, fixing couplings, заслонку and a reducer.

Replacement option for auto without air conditioning

The replacement of the radiator of the stove "Priora" withoutair conditioner with zeroing of the negative terminal AB. Then removes the lining of the frontal lining together with the saddles of the wipers to facilitate the work process. The further operation is carried out in stages:

• The tubes that feed the refrigerant to the nozzles are removed.
• The cover is removed by unscrewing the seven screws.
• The tightening element on the bonnet seal is loosened.
• The flat plugs on the noise insulation of the motor are pinched and unscrewed.
• Insulating elements are removed together with the overlays.
• On the radiator sockets the loops are loosened and dismantled. It will be necessary to prepare a container for the discharge of the antifreeze.
• The wiring to the heater is removed.
• The wire holder is removed and pushed to the side.

Further work is carried out in the car.The bracket fastenings and the brake pedal are loosened, and they are shifted to the side. It is necessary to unscrew the three screws, and access to the radiator will be open. It remains to install a new element and reassemble in reverse order.

Replacement of the radiator of the stove "Priora" with air conditioning

In this case, there are some nuances, although the procedures are similar to each other. You will need to perform the following manipulations:

• The rubber seal of the lining on the windshield is removed to gain access to the fixing elements.
• The noise insulation of the motor shield in the middle part is dismantled (it is first necessary to remove the hoses of the fasteners). Then the fixing screws and self-tapping screws are loosened, the insulating layer is removed to the side.
• It will be necessary to remove the foam rubber seal and remove the cover of the heat exchanger, which is fixed with three screws.
• Dismantle the nozzles by loosening the clamps and lifting the elements up. Next, pull the heat sink on yourself until it comes out of the grooves.

After installing the new part in reversethe sequences are assembled. The main difference is the replacement of the radiator of the stove "Priora", where the air conditioner is installed - do not drain the coolant.

Tools

For the work on the replacement of the heat exchanger, a certain set of tools will be required, namely:

• End wrenches for 10/13.
• Flat and cross screwdrivers.
• The wrench is 8.
• Refrigerant discharge tank.

After removal, the old heat exchanger should be rinsedand check its tightness. If there are signs of leaks on the gaskets, the part can not be repaired, only the radiator replacement for the Priora heater is needed. As you can see, it is not difficult to perform this procedure on your own.
