How to replace the A/C Expansion Valve in an A/C system on Chevrolet Impala?

Recovery of the refrigerant from the a/c system should start any thermal expansion valve (TXV) replacement work. The first step involves removing the Evaporator tube nut which enables disconnecting the Evaporator outlet and inlet tubes from the txv. Sealing washers will be discarded before immediately stopping each pipe opening with an Evaporator cap to stop refrigerant system contamination. Remove the txv to Evaporator bolts from the Evaporator core and extract the txv from its place before discarding the sealing washers. When installing the txv into the Evaporator core position the new sealing washers and fasten them with txv to Evaporator bolts which require tightening up to 7 n.m (62 lb in). Remove devices from the Evaporator inlet and outlet ports then install new sealing washers on each tube before uniting the Evaporator outlet with inlet to the txv. Install the Evaporator tube nut before tightening it to 17 n.m (13 lb ft). The system should receive an evacuation and recharging process in addition to halogen leak detector (J 39400-A) testing of component fittings.
