  Q: How to replace the A/C Expansion Valve on Chevrolet Cobalt?

  A: The first step of A/C Expansion Valve replacement requires removing the charge air cooler inlet pipe. Next, recover the refrigerant. As a first step detach the condenser tube and Evaporator hose from the A/C Expansion Valve, then discard the existing seal washers. Take out the A/C Expansion Valve after removing its bolts while discarding both sets of seal washers. Installation requires placing new seal washers onto the Evaporator core fittings followed by the A/C Expansion Valve connection. The installation of A/C Expansion Valve bolts requires caution because they should be tightened to 7 nm (62 lb in). After positioning new sealing washers on both condenser tube and Evaporator hose fittings the installation of these components to the A/C Expansion Valve can proceed. Fasten the A/C Expansion Valve nut with torque settings at 20 nm (15 lb ft). Reinstall the charge air cooler inlet pipe while performing an evacuation and recharging procedure of the refrigerant system. Complete the leak test on all fittings by using j 39400-a halogen leak detector equipment.
