compressor oil leak

70monte on Mon July 28, 2008 12:17 PM User is offline

Year: 1992
Make: Chevrolet
Model: Cavalier
Engine Size: 2.2L
Refrigerant Type: R-12
Country of Origin: United States

I posted about this previously but have another question. The V5 compressor on my 92 Cavalier has been dripping a couple of drops of clear fluid from the middle of the compressor body for about 2 months. I'm assuming its compressor oil since I cannot find any other leaks on this car. The AC performance has not degraded during this time. It still blows ice cold and will freeze you out of the car. Is it possible to have an oil leak on this compressor but not lose any of the refrigerant? Thanks.

You are losing oil and refrigerant- just very, very, very slowly- soon enough you will be talking about how it used to blow ice cubes- yes leaks can be very slow- if you add some dye- this will confirm your refrigerant oil suspicion.

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......

GM Tech,
Thanks for the reply. I will see if I can find some dye that hooks up to my R-12 ports. All I have is the can for R-134a. I guess I'm going to have to get a new compressor also. Thanks again.

Another quick question. When it comes time for me to replace the Compressor, can I replace my other AC components such as Accumulator, condensor, and lines with ones used on some R134a 1994 Cavaliers? This year is the same body style as my 92. Are there any things about the two AC systems on these cars that won't be compatable? Thanks.

Yeah- big differences- number one is metric -vs- english threaded connections-- everything went metric with 134a
