Gaskets A/C Compressor Chevy 1994

Hey Guys,

My friends has a Chevy Cavalier 1994 with a V6 3.1L. He has a very small leak at the high pressure side of his compressor. He wants to know: what are the gaskets inside the fittings of the tubes?

Are they o-rings?

How many is there?

Thanks for your time,

a 94 should be flat sealing washers, but I could be wrong on that. Cavaliers may have still had O rings since it was a change over year.. If flat washers, should be one 5/8 thin..and one 3/4 thin..Hope this helps...
PS: GM tech should know for sure...

they are sealing washers- both 3/4 inch--------Cavaliers changed from r-12 to 134a in mid -year of 1994- but it still should be sealing washers- all replacement compressors used sealing washers- even if your pump is not the original- sealing washers will work- sealing washer changed occurred before the change to 134a I recall.......

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......

If I can throw in my 2 cents worth, or is that 0.02 cents? First step is to check that block bolt, may be just a little loose, and once in a great while, a guy is lucky. If that doesn't work, check for corrosion, if the corrosion is severe, not so lucky, and no new sealer will work, may end up having to replace the compressor and/or the block. In that case, the refrigerant would have to be recovered, and if corrosion is not the problem, just a burnt up seal, you can see exactly what you need to repair it.

Thing is, you don't know until you look.

just to add my

my buddy runs a local message board and see a lot of spam ads that look like this. they ask some almost right sounding question then throw a link in to some place.

lots of spyware that the links they put up on his... just a heads up incase this is one too.
