Remove the bolt, the ground terminal (A) and the holder (B). Disconnect the field coil connector (C), then remove the thermal protector (D). Replace the thermal protector (A) with a new one and apply silicone sealant (B) to the bottom of the thermal protector. Install in the reverse order of removal.

Discharge the refrigerant (see page 21-94). Remove the cover (A), the relief valve (B) and the O-ring (C). Plug the opening to keep foreign matter from entering the system and the 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 and install and tighten the relief valve. Charge the system (see page 21-96) and check for system performance (see page 21-98).
