WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

Important: If you use the correct washers, there should be a space of 1.2 mm (0.047 in) between the suction/discharge hose block and the compressor rear head.

Clean all of the sealing surfaces with a lint-free rag in order to prevent dirt or foreign material from getting into the following sealing surface components:
- The washers
- The hose block
- The compressor ports
Install the sealing washer onto the pilots of the suction/discharge fitting.
Ensure that the washers are seated against the surface of the block fitting.
Install the hose block to the compressor.
Ensure that the sealing washers are seated within the compressor's machined surfaces.
