Re: Compressor o-rings (newbie question)

Of course, I'm assuming there are o-rings under the temp port caps. I'd gladly use new o-rings but the seal kit I bought doesn't include ones big enough for the compressor. I've looked at a few other o-ring kits for my car and they don't seem to include the bigger o-rings/seals used on the compressor.

Compressor o-rings (newbie question)

This is probably a stupid question, but I'd rather do it right the first time. This is the first time I've purchased a new compressor for my vehicle. The new compressor comes with a cap across the ports where the lines go in. My questions is, when I take that temporary cap off, can I just reuse the ...

Re: equal pressure both sides of the gauges

Not unlikely at all. Modern comps do away with piston rings and have a polymer coating either on the piston or on the cylinder as a means of sealing. If this one wears down too much you get a compressor that is only good at making noise and nothing else. I think prolonged running in this condition ...

Re: equal pressure both sides of the gauges

I did some more testing tonight, and what I found was that basically the compressor does nothing to the pressure readings. I was getting 35 psi on both sides the compressor not running. I added r134a with the pump off and got both sides up to 45psi. Then I turned turned on the AC and heard the clutc...

Re: equal pressure both sides of the gauges

At one point when i thought maybe I'd add a little r134a, I did open the low side gauge to allow the r134a in. But the rest of the time they were both closed. When I added more in the low side, both side immediately went up together and I was suprised. If I didn't see the pump engage, I'd think it w...

equal pressure both sides of the gauges

I'm just starting to diagnose a 2006 Hyundai Elantra, but could use a little help. The clutch engages and spins the compressor. The gauges were showing equal on both the high and low sides. They were at 35 each, then I added a little r134a and they both said 40. So, am I looking at a failed compress...
