How to properly service the A/C Expansion Valve on Chevrolet Malibu?

The first step to replace the A/C Expansion Valve requires a recovery of refrigerant from the system. You should first unmount the surge tank from its mounting bracket before undoing the suction line and liquid line dash clips. After removing the expansion valve (TXV) nuts from both suction line and liquid line you must disconnect the txv lines from the txv. Pull out the txv components after unfastening the screws while immediately sealing all a/c components to stop contamination and throw away the sealing washers. The installation process requires removing the a/c component covers to install fresh sealing washers. Fasten the txv screws with a torque of 7 nm (62 lb in) during txv installation. After installing the txv attach the liquid line then the suction line securing nuts to 20 nm (15 lb ft). Subsequently reinstall the liquid line and suction line to their dash clips while performing an evacuation and subsequent charge of the refrigerant system. The j 39400-a halogen leak detector should be used to conduct a leak test on all fittings before reinstalling the surge tank to its bracket.
