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 pressure in the system, then replace the relief valve.
  1. Recover the refrigerant with a recovery/recycling/charging station (see REFRIGERANT RECOVERY  ).
  2. Raise the vehicle on a lift, then remove the front splash shield (see FRONT SPLASH SHIELD REPLACEMENT ).
  3. Remove the relief valve (A) and the O-ring (B). Plug the opening to keep moisture and foreign material from entering the system and the A/C compressor oil from running out.

  6. Remove the plug, and install and tighten the relief valve.
