  Q: How to Remove and Install a Expansion Valve on Chevrolet Cobalt,HHR,Saturn ION and Pontiac G5?

  A: High-pressure liquid refrigerants can be changed into low-pressure vapors through various means in air conditioning systems. Located at the evaporator of the air conditioner, this conversion is facilitated by passing the coolant through it making sure that it cools thus cooling down the air flow being delivered into vents. Typically, such a change is brought about by a sudden variation in tube sizes; however some vehicles may have a removable controlled orifice within one of their firewalls connected to a certain refrigerant line. Nonetheless, an automatic expansion valve which performs the same function as a controlled orifice. To begin with, discharge your A/C system so that you can remove A/C expansion valve followed by loosening its nut and separating both refrigerant lines from the A/C expansion valve at firewall. Consequently, two securing bolts will come out to allow for removal of the valve itself. On installation, just reverse what was done during removal.
