Before the onset of the cold season, it is necessary to check the car stove for leaks, the he alth of the elements and the integrity of the heat exchanger. This will allow you to prepare the car in a timely manner and make your stay in the cabin comfortable. Replacing the radiator of the Priora stove is carried out in case of any cracks and damage, since this element cannot be repaired.

Signs of problems

The VAZ-2170 car has a regular liquid-type heater that interacts with the cooling system of the power plant. The refrigerant regularly circulates through the heat exchanger, which is a factor influencing corrosion and wear of the part.

Replacing the radiator of the Priora stove may be necessary if the following symptoms are present:

• The heater stopped heating normally.
• The coolant level has dropped noticeably.

First, check the heating element visually. It is necessary to disassemble part of the assembly and inspect the radiator. If traces of rust or limescale are visible, the heat exchanger is likely to leak. It is first necessary to examine the supply and connectinghoses, fixing couplings, damper and reducer.

Option to replace with a car without air conditioning

The replacement of the radiator of the Priora stove without an air conditioner begins with zeroing the negative terminal of the battery. Then the windshield lining is removed along with the wiper seats to facilitate the workflow. The further operation is performed in stages:

• The tubes supplying the refrigerant injectors are removed.
• The overlay is dismantled by unscrewing seven screws.
• The tightening element on the hood seal is unscrewed.
• The flat plugs on the sound insulation of the motor are hooked on and turned out.
• Insulating elements are removed together with overlays.
• Clamps are loosened and dismantled on the radiator pipes. You will need to prepare a container for draining antifreeze.
• The wiring connected to the heater is removed.
• The wire holder is removed and set aside.

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

Replacing the radiator of the Priora stove with air conditioning

There are some nuances in this case, although the procedures are similar. You will need to perform the following manipulations:

• Removes the rubber seal of the windshield lining to gain access to the locking elements.
• Dismantlednoise insulation of the motor shield in the middle part (you must first remove the mounting hoses). Then the fixing screws and self-tapping screws are unscrewed, the insulating layer is removed to the side.
• You will need to remove the foam seal and remove the heat exchanger cover, which is attached with three screws.
• The pipes are dismantled by loosening the clamps and lifting the elements up. Next, pull the oven radiator towards you until it comes out of the grooves.

After installing a new part, the installation is carried out in the reverse order. The main difference that the replacement of the radiator of the Priora stove, where the air conditioner is installed, has is that it is not necessary to drain the coolant.

Toolkit

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

• Socket keys for 10/13.
• Flat and Phillips screwdrivers.
• Wrench for 8.
• Refrigerant drain tank.

After removing the old heat exchanger, rinse and check its tightness. If traces of a leak appear on the seals, the part cannot be repaired, only the Priora stove radiator needs to be replaced. As you can see, it is not difficult to perform this procedure yourself.
