- Move thermal harness from supermanifold to side.
- Use a pick to pull the locking tab downward, and then pull toward the front of the vehicle to remove the EXV coil.
-
Remove the EXV core from the
supermanifold.
NoteUse of the following tool(s) is recommended:
- 1588741-00-A - HVAC Socket Kit
- 3 in extension
- 3/8 to 1/2 in Adapter
- Flex head ratchet/flex head torque wrench
Install
- Lubricate the EXV threads and O-rings with the appropriate A/C oil. See Fluids and Capacities for A/C oil specifications. Then hand-start the valve into the supermanifold.
