2007 Buick LaCrosse A/C Expansion Valve Parts and Q&A

  • Q: How to replace the A/C Expansion Valve in an A/C system on 2007 Buick LaCrosse?
    A: Recovery of refrigerant must occur as the first step before replacing the thermal expansion valve. The first step involves unfastening the Evaporator tube to thermostatic expansion valve (TXV) nut before removing the Evaporator outlet and inlet tube from the txv. Cap or tape the exposed inlet and outlet tubes of the Evaporator before discarded sealing washers to avoid contaminating the refrigerant system. The next step involves logging out of the txv to Evaporator bolts to extract the txv from the Evaporator core before discarding both sealing washers. The installation process requires new sealing washers to be inserted on the Evaporator core followed by txv installation onto the core while following fastener notice service precautions. An advanced torque of 7 n.m (62 lb in) should be used to tighten txv to Evaporator bolts. Take away tape or caps from Evaporator inlet and outlet tubes before applying new sealing washers to these connections. Install the Evaporator tube nut on top of the txv then tighten it to 17 n.m (12.5 lb ft). The a/c system needs evacuation then recharging after which one should conduct a leak test on components using halogen leak detector (J 39400-A).
