Evaporator Expansion Valve Removal and Installation
3. Expansion Valve - Remove

1.
Remove the expansion valve (A).

NOTE:
Screw the A/C pipe fixing both in the expansion valve about 4 to 6 heads. Hold the bolts and pull them out.
Be careful not to damage the expansion valve.

4. All Removed Parts - Install

1.
Install the parts in the reverse order of removal, and note these items:

New O-rings should be used at each fitting. Prior to installation, apply a thin coat of the same refrigerant oil used in the A/C compressor. Be sure to use the correct O-rings for refrigerant types to avoid leakage.
