Fig 1 TRS90 Compressor:

The compressor compresses the low pressure refrigerant vapor from the evaporator into a high pressure, high temperature vapor. The Scroll TRS-90 Compressor is used on all models. The system uses polyalkylene glycol synthetic wax-free refrigerant oil SP-15 PAG.

The TRS9O is a fixed displacement type compressor.

CAUTION: Cleanliness is extremely important. Clean the surfaces around the suction and discharge ports of the compressor before opening the system. If compressor is removed from vehicle, apply tape to the opened ports to prevent any contamination.
