A/C Compressor Relief Valve Removal and Installation

NOTE: If the A/C compressor relief valve released refrigerant to the atmosphere, determine and correct the cause of the excessive system pressure, then replace the relief valve.

1.	A/C Refrigerant - Recover

2.	Splash Shield - Remove

3.	A/C Compressor Relief Valve - Remove

NOTE: Plug the opening to keep moisture and foreign material from entering the system, and the A/C compressor oil from running out.

4.	All Removed Parts - Install

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

If the A/C compressor relief valve released refrigerant to the atmosphere, determine and correct the cause of the excessive system pressure, then replace the relief valve.

Clean the mating surfaces.

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 HFC-134a (R-134a) to avoid leakage.

Charge the system with the specified amount of R-134a refrigerant.
