99 Cavalier...Delphi Compressors?

aegis on Sun April 24, 2011 1:17 PM User is offline

Year: 1999
Make: Chevy
Model: Cavalier
Engine Size: 2.2
Refrigerant Type: R134a
Country of Origin: United States

The clutch bearing went out on my compressor over a year ago and the AC started blowing hot shortly after. I plan on replacing the compressor, accumulator and orifice tube myself, and I'll bring it to a mechanic to vac and charge the system.

I was planning on purchasing a Delphi compressor, but I was wondering if anyone here has any experience with that particular brand. Good or bad? Also, how much PAG oil does the compressor require (the Delphi compressor is shipped dry)? Does the accumulator or any other component require PAG oil as well?

System oil capacity is 9.0 ozs--- So you must figure out if you are flushing, or just replacing components- how much oil to re-install. The V-5 compressor usually hold 3 - 3.5 ozs in its crankcase-- the accumulator hold about 3 ounces, most of it is saturated and soaked up into the internal desiccant bag.

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......
