qatcool Posted June 10, 2012 Share Posted June 10, 2012 Last Year I had my A/C compressor replaced ( AC delco). it seems fine, now that summer has come, i dont feel that it is cooling especially during noon. any body here knows whats the working pressure of the refrigerant?

clkindred Posted June 13, 2012 Share Posted June 13, 2012 Sorry my friend but I don't know that off the top of my head, and even if I did I think there is a chance your A/C is different that US models. Any NPORA members out there able to shed some light on this? Link to comment Share on other sites More sharing options...
devonianwalk Posted June 13, 2012 Share Posted June 13, 2012 (edited) Any NPORA members out there able to shed some light on this? Not me. I recharged mine with the self refill bottle that had a simple to use pressure gauge built on to it. It didn't give the pressure rather, it had a color coded "yellow" (low) "green" (just right) "red" (to high).

Yes indeedy, we like to use colors here in the USA, much easier than numbers :laugh: :laugh: Link to comment Share on other sites More sharing options...
theexbrit Posted June 24, 2012 Share Posted June 24, 2012 Most ac systems are usually 20-40 psi for the low pressure side (with the ac running) & 200-225 psi for the high side wit R12 or 225-250 psi for R134a. Link to comment Share on other sites More sharing options...
Tungsten Posted July 2, 2012 Share Posted July 2, 2012 Isn't there a sticker under the hood? I know there is on mine. You should also be able to find this information on the compressor. Link to comment Share on other sites More sharing options...
