You can Select Your Vehicle to check if 52485723 fits your vehicle.

To perform this procedure, you will need refrigerant oil and new O-rings for the fittings by which the condenser is attached to the rest of the system, as well as tape or caps to seal off the openings. Make sure you also have enough wrenches so you can always use a backup wrench when you disconnect or connect fittings. Discharge the refrigerant from the A/C system using an approved recovery/recycling machine, remove the bolts which fasten the condenser retainers to the radiator/condenser support, disconnect the two refrigerant line connectors, then seal the openings, lift the retainers and upper insulators off the top of the condenser, lift the condenser straight up and out of the area between the support and the front bumper, install the condenser in reverse order, being careful to locate the bottom squarely into the lower insulators, and making sure that the upper insulators are in place in the brackets, install new O-rings coated with clean refrigerant oil, and screw together the high and low pressure connections, using a backup wrench, torque each to 18 ft. lbs. (23 Nm), install the mounting bolts and tighten to 7 ft. lbs. (9 Nm), have the system evacuated and then recharge it.
