Q: How to remove and replace A/C Condenser on Ford Explorer Sport Trac?
A: The accumulator/drier and the orifice tube should be replaced whenever the condenser is replaced. First, have the air conditioning system discharged and recovered. Then, remove the battery. Drain the cooling system. On 2001 and later models, remove the air cleaner assembly. On models through 2000, remove the Radiator. On later models, the radiator can be unbolted and leaned back from the radiator support to allow condenser removal. Disconnect the refrigerant lines from the condenser. On 1996 and earlier models, this requires a spring-lock coupling tool similar to that used for fuel injection lines. You remove the metal clips from the connection, then use the tool to release the coupling. On later models the condenser lines have bolted flanges. Working from below, remove the mounting nuts from the condenser studs. On 1996 and 1997 models, the condenser bolts (no studs) to the radiator support, and on 1998 through 2000 models, the condenser has plastic squeeze-tabs that fit into plastic receptors on the body. On 2001 and later models, the condenser is retained by bolts. Lift the condenser out of the vehicle and plug the lines to keep dirt and moisture out. If the original condenser will be reinstalled, store it with the line fittings on top to prevent oil from draining out. If a new condenser is being installed, pour 1 ounce of refrigerant oil into it prior to installation. Reinstall the components in the reverse order of removal. Be sure the rubber pads are in place under the condenser. Be sure the seals are in place around the condenser. Have the system evacuated, recharged and leak tested by the shop that discharged it.
