Removal

^ The expansion valve is a block type valve. The compressor vacuum hose is located in a pressure plate together with the pipe from the desiccant container The pressure plate is connected with three screws to the expansion valve. The sensitive body is built into the expansion valve, which gives a more exact sensing of refrigerant temperature.

^ The new expansion valve is available in two versions, one for the R134a system and one for the R12 system. In order to eliminate the risk of these being confused, the two valves each have different guide pins. The guide pin should be aligned with a hole in the pressure plate in the connection to the A/C pipe. Seen from in front of the car, the guide pin is located on the left-hand side on the expansion valve in the R134a system, and on the right-hand side in the R12 system.





1. Release the expansion valve as described in points 1-2 in the description of removing the evaporator. Refer to "Front Evaporator Core Removal".
Service and Repair.

CAUTION: Both the desiccant container and the compressor oil in the R134a system absorb water form the air, which cannot then be removed. The system must therefore never be left open.

2. Remove the expansion valve and plug the holes.
