2008 Chevrolet Equinox A/C Hose Parts and Q&A

• Q: How to replace the front A/C Hose in the HVAC system on 2008 Chevrolet Equinox?

  A: The initial step to replace the liquid line in hvac involves refrigerant recovery with halogen leak detector (J 39400-A). Start this procedure by taking off the left headlamp and surge tank along with the washer bottle and disconnecting the battery plus removing all bolts from the battery box. Disconnect the battery cable nut from the wheelhouse after removing the liquid line strut tower retaining nut. Work starts with the removal of liquid line harness and vent hose retainers from their position on the liquid line and proceeds with evaporator outlet hose removal while unfastening the liquid line retainer plate nut from the thermal expansion valve (TXV). Pull the evaporator outlet tube with liquid line out of the thermal expansion valve before disconnecting the liquid line from its condenser mounting. Continue by disconnecting and removing the liquid line altogether. Change the liquid line body bolt retention and move the battery box towards the vehicle center for routing purposes before directing the line above the battery box and ground lug. Raising the rear section of the liquid line will extract it from the automobile before throwing away the sealing washer. Mev install protective caps which prevent contamination on the condenser as well as the evaporator outlet hose and txv. During installation the technician must guide the new liquid line underneath the battery box and ground lug before reattaching and properly tightening the negative battery cable nut to 12 n.m (106 lb in). Before installation of the condenser end of the liquid line users should first remove protective caps then add a new sealing washer followed by placement of the condenser end. After using pliers to maintain the fitting position tightly turn the liquid line nut until it reaches 20 n.m (15 lb ft) torque before installing the bolt which needs to be tightened to 9 n.m (80 lb in). Unseal the txv as well as the liquid line and evaporator outlet hose then install fresh seal washers to both lines. After tubing the txv with the liquid line and evaporator outlet hose it is crucial to tighten the retainer plate nut to 20 n.m (15 lb ft). The technician should install the four battery box bolts at 15 n.m (11 lb ft) and the outside battery box bolt at 10 n.m (86 lb in). Fasten the battery in its place before connecting the liquid line to the strut tower and torque the liquid line nut to 9 n.m (80 lb in). Reinstall the surge tank and washer bottle together with the left headlamp before connecting the liquid line retainers and vent tube retainers to the liquid line assembly. The a/c system requires recharging before performing a leak detection test of the affected a/c joints using the halogen leak detector (J 39400-A).
