Re: Replaced compressor, failed again 9 days later. Advice sought

It took me a little while to make the conversions to US measures and interpret them, but here's what I think is going on. Given an ambient temp of 21C (70F) and a vent temp of 5C (41F), the LP gauge reading of 2.0BAR (29PSI) seems just about right. However, the HP gauge reading of 7.5BAR (109PSI) is...

Re: Stuck Compressor Clutch Plate: Suggestions on Removal

Glad to learn you finally got the darn thing off. And thanks for your detailed posts, to which I'll refer if I ever face the same problem.

Re: Replaced compressor, failed again 9 days later. Advice sought

I wouldn't worry about seepage at the Schrader valves as they're normally not bubble-tight anyway. It's the caps that do the actual sealing. Just ensure they're in good condition and snug them down well by hand. I like to put a little PAG oil on the internal o-rings, too. So the leak(s) must be else...

Re: Replaced compressor, failed again 9 days later. Advice sought

Yes, you are correct. A little theory: The compressor "compresses" the refrigerant, now in a gaseous state, from its internal chambers to the condenser and receiver/dryer, which are on the high-pressure side of the system. The condenser then changes the state of the refrigerant from a HP g...

Re: Replaced compressor, failed again 9 days later. Advice sought

The Auris is a European-spec vehicle that's not sold in the USA, where I am. So I'm not overly familiar with it. But a quick Internet search indicates that Denso was the OEM for your compressor. You could check with this site's sponsor to see whether they can source one of those for you or a compara...

Re: Replaced compressor, failed again 9 days later. Advice sought

The tech-verified 100 g of the correct oil in the new compressor should have been enough unless a lot of it leaked out someplace during the nine days you were operating the system. You could check for that yourself by looking for any oily spots on or near the A/C system's lines and components. Anoth...

Re: Replaced compressor, failed again 9 days later. Advice sought

You mentioned that the first time the shop recovered the charge, only 220 g (7.8 oz) came out. That's a little less than half the refrigerant charge (450 g, 15.9 oz) the specs for your vehicle call for. So it was quite low to begin with. On replacement of the compressor (but perhaps not the receiver...

Re: Don't know how much oil I lost

I think cool2bcool is correct. In all probability, what you saw come out was mostly liquid refrigerant, which immediately evaporated, and a little bit of oil, guessing maybe an ounce or so. If the system is still open, I would change the receiver/dryer (inexpensive at about $20 for an OEM Denso part...

Re: 2002 GMC Envoy AC problems and what Ive tried to fix them

I believe the experts on this board would strongly advise against introducing any type of sealer into your AC system, and I agree. Sealers and other "miracle enhancers" often clog-up components and create additional and costly problems that weren't there before. Cans with the trigger, hose...
