How to properly service the A/C Expansion Valve on a GMC Envoy?

The procedure to replace a thermal expansion value begins by removing the Evaporator core auxiliary followed by eliminating foam insulators from Evaporator core auxiliary lines and thermal expansion value auxiliary. Begin by loosening the flare nuts from the thermal expansion valve-auxiliary using a back up wrench before removing its sensing bulb that comes with a retaining clip from the Evaporator core-auxiliary lines. After removing the thermal expansion valve-auxiliary, carefully take it out of the Evaporator core-auxiliary before disposing of its o-ring seals while using caps or tape to seal the lines from Evaporator core-auxiliary contamination. Uncover the Evaporator core-auxiliary lines by removing their cap or tape to start installation while adding new o-rings and attaching the thermal expansion valve-auxiliary to these lines. The installation of foam insulators on both the thermal expansion valve-auxiliary and Evaporator core-auxiliary lines proceeds with back up wrench settings for 5 n.m (44 lb in).
