Q: How to identify and replace the A/C Expansion Valve on Chevrolet Colorado?
A: Begin the replacement process of the Air Conditioning Evaporator Thermal Expansion Valve by recovering the refrigerant first. The procedure starts with removing the mounting stud nut followed by a disconnection of the evaporator tube and the compressor suction hose from the TXV. After removing both the TXV bolts users need to discard the seal washers and finish the process by extracting the TXV. New seal washers need installation on both evaporator core fittings followed by TXV positioning and tight installation of TXV bolts at 7 Nm (62 lb in). Secure the connections of evaporator tube and compressor suction hose fittings using new sealing washers before installation of the TXV. Fasten the TXV nut with a torque of 20 Nm (15 lb ft). Evacuation of the refrigerant system must occur before adding new gas then a leak test of fittings will be performed utilizing the J 39400-A Halogen Leak Detector.
Q: How to replace the A/C Expansion Valve of the second design on Chevrolet Equinox?
A: The first step when replacing the A/C Expansion Valve of the second design is to check for leaks using the Halogen Leak Detector (J 39400-A). Refrigerant recovery must be performed first followed by the removal of evaporator outlet hose and liquid line retainer plate nut from A/C Expansion Valve. The work area should remain clean while only using new tools to prevent contamination of O-ring sealing surfaces. Take out the evaporator outlet hose and liquid line from the A/C Expansion Valve before disposing the sealing washers. Protective caps should be installed on both the evaporator outlet hose and liquid line to stop contamination during the process. Remove the A/C Expansion Valve bolts from the backing plate before extracting the A/C Expansion Valve as well as backing plate from the vehicle while discarding the O-rings from the evaporator pipes and applying protective caps for contamination prevention. The installation process demands clean and dry and free of lint junctions on the evaporator pipes before installing new O-rings. Place the A/C Expansion Valve into position and its matching backing plate onto the evaporator pipes before screwing A/C Expansion Valve bolts until they reach 8 N.m torques (71 lb in). The next step requires removal of protective caps from the liquid line and evaporator outlet hose before adding new seal washers to prepare for attachment of these parts to the A/C Expansion Valve while securing them with a retainer plate nut at 20 N.m (15 lb ft). The A/C system needs evacuation before charging while the affected A/C joints need testing for leaks through use of the Halogen Leak Detector (J 39400-A).
Q: How to replace the A/C Expansion Valve on Chevrolet Malibu?
A: One must first recover the refrigerant before starting the thermal expansion valve (TXV) replacement. The repair process starts by taking off the surge tank from its bracket and progresses to detach the suction line and liquid line from the dash clip. Begin by taking off both the liquid line and suction line nut from the TXV before disconnecting all components from the valve. You should carefully uninstall the TXV screws then remove the TXV while immediately attaching caps to all A/C components to stop system contamination. After removing the sealing washers from the A/C components you should uncover them before installing new sealing washers. Fix the TXV unit along with its screws until they reach 7 N.m (62 lb in). The suction and liquid assembly lines must be reinstalled to the TXV before tightening the nut to 20 N.m at 15 lb ft. The final steps include reattaching the suction and liquid lines to the dash clip after evacuating and charging the system using the Halogen Leak Detector J 39400-A to check for leaks. You can then put back the surge tank to its bracket.
