SERVICE INFORMATION

GMSPO A/C compressors include a seal washer kit. These kits contain various color edge painted washer seals and inserts in which only two washers and possibly one insert are used. It has come to our attention that some packaging discrepancies were found and some of the seals cannot be properly identified for installation.

These seals are very close in size and some of the seals were inadvertently edge painted the wrong color or not painted.

The attached charts will help to properly identify the seals. See Fig 1 and Fig 2 . Use the attached charts by placing the seal over the pictured seal to identify inside and outside diameters and thickness. Because these seals are very similar in size, specifications are also listed in the charts.

Fig 2: A/C Compressor Seal Washers & Hose Blocks - Identification

NOTE: If seals are damaged upon installation, obtain new seal kit. Seals will be available separately at a later date.

NOTE:

Style "V" uses only "slim line" sealing washer G.
Match block diagram to block for proper use.
Determine compressor port and block pilot diameters to determine proper seal washer/insert code letters.
1. If both pilots have the same diameter, they are 5/8).
2. If both compressor ports have the same diameter, they are 5/8).
Remove proper washer and insert from kit and install onto block fitting. Inserts must be fully seated, and sealing washers must be bottomed out against the block surface.
Position block, hold in place, and hand tighten bolt or nut; then torque to 34 N.m (25 lb-ft). A small space between the hose block and compressor head is normal, but gasket has sealed.
All sealing washers have a smaller O.D. than the compressor spot surface recess diameter that they must fit into. Verify prior to assembly.

NOTE: All sealing surfaces must be lint and dirt free.
