The Air conditioning circuits are filled with either R12 (1989 - 1992) or R134a (1993 - on).

Procedure from Johan Huis

1. Remove the air box.
2. Lossen the coolant lines to the compressor.
3. Jack up the car and place jackstands.
4. Remove the plastic protection cover from under the car.
5. Undo the v-belt adjustment bolt locking nut.
6. Slacken and remove the v-belt.
7. Undo the electrical connector to the compressor.
7. Undo the bolt that holds the v-belt adjustment bracket to the engine block.
8. Undo the upper mounting bolt.
9. Take out the compressor.

Replacement is reversal as removal. Be sure to use new O-rings when installing the new compressor.

My car is an 1987 E32 and the original compressor had a 1 pin plug while the new compressor had a 3 pins plug. BMW sells an adaptor cable with part number 64 52 1 384 964. I don't know if this also applies to the E34

It's a tight fit and a bit of a puzzle. By pulling the wire channel forward and moving the air collector from side to side while tipping it, the air collector will come out. Now visible is a thin plastic air ... (more)
