Compressor oil question

2ndgenteg on Thu July 24, 2008 7:32 PM User is offline

Year: 1993
Make: Acura
Model: Integra
Engine Size: 1.8
Refrigerant Type: R134a retrofit
Country of Origin: United States

I just received my new compressor from, item #20-10814. I replaced the evaporator, expansion valve, and dryer. I'm thinking of either flushing the original condenser or replacing it, since almost everything else was changed. The new compressor came in an unmarked box and no instructions. My question is: What type & weight oil do I use and how much? Thanks for any help

7 ounces of PAG46.


When considering your next auto A/C purchase, please consider the site that supports you:

When you retrofit from R12 to R134a Ester Oil should be used. Since there is only one viscocity of Ester Oil, weight is not an issue but the quantity should be 7 ounces. The reason you should use Ester Oil and not PAG 46 Oil is the R12 that was in the system leaves a residual when mixed with moisture creating hydrochloric acid. Ester Oil has the ability to neutralize hydrochloric acid. There is a Universal PAG Oil that can be used #2468. The Ester Oil number is 2408. If you decide to flush your old condenser there is a flush that should work for you, #2405. I hope this helps answer your questions.

Keepin it Cool!
