Lexus 88320-48120 Compressor Assembly

The receiver/drier should be replaced whenever the compressor is replaced. First, have the refrigerant discharged by an automotive air conditioning technician. Next, disconnect the negative cable from the battery. Remove the drivebelt from the compressor and take off the splash shield from below the engine compartment, if equipped. For 2003 and earlier Lexus models, remove the alternator. For 2008 and later Highlander models and 2009 and later RX 350 models, remove the radiator. Detach the wiring connector and the refrigerant lines, then 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.

The drivebelt from the compressor should be removed.
