• Q: How to replace the Rear A/C Hose on 2010 Chevrolet Corvette?

  A: The first step to replace the air conditioning evaporator rear tube requires recovering refrigerant from the a/c system. Finishing the first step entails removing both the battery and the Intake Manifold. Begin by disconnecting two parts of the front evaporator line. The first is the body retaining clip while the second is an electrical connector for the refrigerant pressure sensor. Cap and tape all open a/c components before disconnecting the a/c tube connectors from the evaporator rear line assembly. Remove the front evaporator inlet line of the a/c compressor line from the evaporator rear line assembly using proper methods to discard o-rings before cap or tape each line. Begin by removing the heater pipe bracket retaining nut from the cowl stud plus the thermal expansion valve (TXV) block fitting nut . After disconnecting the evaporator rear line assembly from both txv and retainer bracket stud you must remove the unit from the vehicle and discard the seal washers and tape or cap the txv. To perform the installation procedure begin by adding the specified pag oil amount to the new evaporator rear line assembly then install new seal washers before correctly connecting the assembly to the retainer bracket stud and txv. Before tightening the installation proceed by fixing the txv block fitting nut to 20 nm (15 lb ft) and then the heater pipe bracket retaining nut to 10 nm (89 lb in). The installation process requires removal of caps and tape from the front evaporator line with a/c compressor line followed by new o-ring installation to the rear evaporator line assembly. The a/c compressor line and front evaporator line should then connect to the evaporator rear line assembly. Connect the a/c tube connectors together with the refrigerant pressure sensor electrical connector before joining the front evaporator inlet line into the body retaining clip. After reinstalling the Intake Manifold and the battery permit the a/c system evacuation and recharging procedure. Complete the leak detection process of fittings through the use of j 39400-a - halogen leak detector.
