A/C Compressor Relief Valve Replacement (With A/C)

A/C Compressor Relief Valve Replacement

NOTE: If the A/C compressor relief valve has opened, diagnose and correct the cause of the excessive A/C refrigerant pressure, then replace the relief valve.

1. Recover the refrigerant with a recovery/recycling/charging station. A/C Refrigerant Recovery (With A/C)

2. Remove the relief valve cover (A), the relief valve (B), and the O-ring (C). Plug the opening to keep foreign matter from entering the system and the A/C compressor oil from running out.

3. Clean the mating surfaces.

4. Replace the O-ring with a new one at the relief valve, and apply a thin coat of refrigerant oil before installing it.

5. Remove the plug you installed in step 2, then install and tighten the relief valve.

6. Charge the system. A/C System Charging (With A/C)
