After replacing the engine in the camaro I am reattaching the lines to the compressor. One sealing washer is red and one is green. Which one goes on which hose, side however to describe it? They must be different since they are a different part number or maybe they are idiot proof. I have yet to put them on. Thanks for the help.
Which ever creates a flat surface for the manifold. If they are both the same thickness, check to see if one has a different oval for the hose set to fit through.
If you're connecting a "flat" manifold to a "stepped" compressor or vice versa you need washers of different thicknesses. Early (R-12 type) stuff was flat and later (R-134a type) was stepped.
Red is usually for discharge side in a stepped manifold connection,
Evidently your '92 has a replacement compressor- they used o-rings OEM-- therefore you use the manifold seal kit when this happens--Replacement compressors are all stepped manifolds.
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......
