The receiver/drier should be replaced whenever the condenser is replaced. Begin by having the refrigerant discharged by an air conditioning technician. For Highlander models, remove the radiator grill, while for Lexus models, the front bumper needs to be taken off. On Highlander models, either remove the radiator support structure or the radiator upper mounts. Disconnect the inlet and outlet fittings, capping the open fittings immediately to prevent moisture and dirt from entering the system. For 2013 and earlier models, remove the mounting fasteners, push the radiator back toward the engine, and then push the condenser rearwards until it is free of the radiator support and can be pulled up and out of the vehicle. For 2014 and later models, squeeze the upper retaining clips together to unclip the top of the condenser, then lift it straight up and out. For 2013 and earlier models, install the condenser, brackets, and bolts, ensuring the rubber cushions fit properly on the mounting points. For 2014 and later models, slide the condenser down until the two tabs on the bottom are inserted into the slots, then press the top corners onto the clips until they lock into place. Reconnect the refrigerant lines, using new O-rings where necessary, and reinstall the remaining parts in the reverse order of removal. Finally, have the system evacuated, charged, and leak tested by the shop that discharged it.
