Sealing washers for R4. Not sure what sealing washers to use. Should the metal part of the washer be flush with the compressor after setting the washer into the port grove? What washers/color do I use 83 GMC PU?
red on high side ,, thin on low side
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
Thanks GM tech. When I set the thin washer about 1/16 thick in the port grove it's slightly smaller. Compared to how the red washer fits. Is that normal?
