Expansion Valve: Service and Repair
A/C Expansion Valve Replacement
1. Remove the evaporator core. See: Evaporator Core/Service and Repair
2. Remove the insulator (A) and bolts, then remove the expansion valve (B) and O-rings (C).
3. Install the expansion valve in the reverse order of removal, and note these items:
-
Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the correct
O-rings for HFC-134a (R-134a) to avoid leakage.
-
Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture absorption.
-
Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts the paint, wash it off immediately.
-
Make sure that there are no air leaks.
-
Charge the system. See: Service and Repair/A/C System Charging
