Lexus 88370-33020 Compressor Assembly, W/MOTER

The receiver/drier should be replaced whenever the compressor is replaced. First, have the refrigerant discharged by an automotive air conditioning technician. Disconnect the cable from the negative battery terminal. Raise the front of the vehicle and support it securely on jackstands, then remove the passenger's side front wheel and the lower inner fender corner splash shield(s). Drain the cooling system. Remove the drivebelt from the compressor. Remove the alternator. For 2009 and earlier four-cylinder models, detach the upper radiator hose from the thermostat housing and remove the clamp that supports the refrigerant lines. For 2010 and later four-cylinder models and all V6 models, remove the air cleaner assembly and air inlet duct, then remove the front bumper and the radiator. For all models, detach the electrical connector and the refrigerant lines, unbolt the compressor, and lift it from the vehicle. If a new or rebuilt compressor is being installed, follow the directions that come with it regarding the proper level of oil prior to installation. Installation is the reverse of removal; replace any O-rings with new ones specifically made for the purpose and lubricate them with refrigerant oil. Finally, have the system evacuated, recharged, and leak tested by the shop that discharged it.
