A/C Compressor Relief Valve Replacement

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
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. Recover the refrigerant with a recovery/recycling/charging station (see RECEIVER/DRYER DESICCANT REPLACEMENT ).
  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 installed in step 2, then install and tighten the relief valve.
  6. Charge the system (see SYSTEM CHARGING ).
