How is an A/C Expansion Valve Installed in a Cooling System on Jeep Liberty?

Prior to installing the expansion valve, first take off all the tape, plugs and anything else covering the evaporator tube and refrigerant line fittings, as well as each port of the expansion valve. Use clean refrigerant oil to coat the new O-ring seals and then set them onto both the refrigerant line and evaporator tube fittings, using only the recommended O-rings for R-134a and the proper oil recommended for the A/C system and its compressor. Then, mount the A/C expansion valve (2) onto the evaporator tube tapping block (3) and attach it with two bolts (1) that you tighten to 11 Nm (97 in. lbs.). Join the suction line (1) which is from the A/C, with the liquid line (4) going to the A/C. Next, connect the A/C expansion valve (3), make sure the nut (2) is there and tighten it to 23 Nm (17 ft. lbs.). Fit the negative battery cable, clear the refrigerant through the system and fill it back with refrigerant.
