## A/C Compressor Relief Valve Replacement

1. | Recover the refrigerant with a recovery/recycling/charging station.

2. | Remove the relief valve (A) and the O-ring (B). Plug the opening to keep foreign matter from entering the system and the 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, and install and tighten the relief valve.

6. | Charge the system.
