How to Properly Install an A/C Expansion Valve on Buick Enclave?

The first task for A/C Expansion Valve replacement is to retrieve any refrigerant. Beginning the replacement process starts with unattaching the duct to the air cleaner outlet and disconnecting the windshield washer solvent heater when present. The installation starts by detaching the A/C Expansion Valve tube from the A/C Expansion Valve after discarding both seal washers and A/C Expansion Valve bolts before removing the unit itself. The installation of the A/C Expansion Valve seal strip should begin by positioning it over the dome at the top of the A/C Expansion Valve before extending down both sides. New seal washers should be installed on evaporator core fittings before placing the A/C Expansion Valve into position and screwing in the A/C Expansion Valve bolts with assistance from a small Phillips screwdriver. Secure the A/C Expansion Valve bolts at 5 Nm (44 lb in) torque. Then install new sealing washers to the evaporator A/C Expansion Valve tube fittings followed by connecting the condenser tube and evaporator hose to the A/C Expansion Valve and tightening the A/C Expansion Valve nut to 20 Nm (15 lb ft). Complete the process by evacuating and refrigerant system charging. Reinstall the windshield washer solvent heater prior to installing the air cleaner outlet duct when the heater was removed. Finally the J 39400-A Halogen Leak Detector should check for leaks in the fittings.
