What steps should be followed when replacing an A/C Compressor in an air conditioning system on Volkswagen Passat?

The orifice tube is to be replaced whenever the compressor is changed because of any internal damage. The compressor must be replaced and in that case, so is the accumulator. Start with emptying the air conditioning system and putting the car on jackstands. Take out the splash shield beneath the engine (where fitted), and install the radiator support panel in the work position. Take away the NC compressor drive belt and in V6 engines, the oil filter might have to be taken off to get to the compressor. Sanitize the environment surrounding the refrigerant line fittings of the compressor and at this point disconnect the electrical connector with the compressor having a speed sensor which is also to be disconnected. Uncouple the suction and discharge lines and make sure to close open fittings to avoid entry of dirt and moisture and dispose the seals between the plate and compressor. Unscrew the mounting bolts of the compressor, disconnect the compressor to the mounting bracket and remove it out of the engine compartment. When changing a compressor, pour the used compressor oil into a graduated cylinder and add the new compressor refrigerant oil in the same quantity to the new compressor and follow instructions that may be included. There are replacement compressors that might be filled with refrigerant oil, in this case, follow the instructions on draining the oil before putting together the compressor. Install the compressor line fitting bolt with the new seals greased with clean refrigerant oil and screw tightly. Lastly, vacate system and recharge then leak test through a dealership service department or automotive air conditioning repair facility.

Volkswagen Passat A/C Compressor

The Volkswagen Passat A/C Compressor is the core of the cabin cooling system, and it compresses low-pressure refrigerant gas into a high-pressure hot gas within a short period of time to ensure that cold air is provided later to flood the vents. The hot gas is then passed into the condenser where it releases its heat to the outside air, cools down, and is passed into the evaporator where it is cooled further by the blower pushing chilled air through the vents. This loop activates when the A/C switch lights and maintains cabin temperatures constant even when it is very hot. The initial Volkswagen vehicles were based on the R12 refrigerant that relied on mineral oil and caused environmental concerns. In the early 90s the company applied R134a, which is a cleaner gas that requires different oil and special fittings, hence R12 compressors cannot fit in new systems. Although the two configurations are identical in terms of physics, they differ in seals, threads applied on the hose, and lubricants that are applied, and therefore the selection of parts based on years is paramount. A unit has a belt-driven pulley, pistons or swash plate, and an electric clutch that is engaged on command, and therefore the A/C Compressor has to handle high rpm and innumerable on/off cycles. A healthy charge of refrigerant will ensure that the Volkswagen unit will spin, protect the clutch, and make the Passat keep the air chilled mile after mile. A good A/C Compressor makes all the modern cabins of Volkswagen enjoyable irrespective of the predictions.

Q: What steps should be followed when replacing an A/C Compressor in an air conditioning system on Volkswagen Passat?
A:
The orifice tube is to be replaced whenever the compressor is changed because of any internal damage. The compressor must be replaced and in that case, so is the accumulator. Start with emptying the air conditioning system and putting the car on jackstands. Take out the splash shield beneath the engine (where fitted), and install the radiator support panel in the work position. Take away the NC compressor drive belt and in V6 engines, the oil filter might have to be taken off to get to the compressor. Sanitize the environment surrounding the refrigerant line fittings of the compressor and at this point disconnect the electrical connector with the compressor having a speed sensor which is also to be disconnected. Uncouple the suction and discharge lines and make sure to close open fittings to avoid entry of dirt and moisture and dispose the seals between the plate and compressor. Unscrew the mounting bolts of the compressor, disconnect the compressor to the mounting bracket and remove it out of the engine compartment. When changing a compressor, pour the used compressor oil into a graduated cylinder and add the new compressor refrigerant oil in the same quantity to the new compressor and follow instructions that may be included. There are replacement compressors that might be filled with refrigerant oil, in this case, follow the instructions on draining the oil before putting together the compressor. Install the compressor line fitting bolt with the new seals greased with clean refrigerant oil and screw tightly. Lastly, vacate system and recharge then leak test through a dealership service department or automotive air conditioning repair facility.
