A/C Compressor Relief Valve Replacement
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.
- Recover the refrigerant with a recovery/recycling/ charging station (see REFRIGERANT RECOVERY ).
- Remove the relief valve (A), and the O-ring (B). Plug the opening to keep foreign matter from entering the system, and the A/C compressor oil from running out.
- Clean the mating surfaces.
- Replace the O-ring with a new one at the relief valve, and apply a thin coat of refrigerant oil before installing it.
- Remove the plug you installed in step 2, and install and tighten the relief valve.
- Charge the system (see SYSTEM CHARGING ).
