Re: Oil loss when pulling a vacuum?

Essentially none. Even under those vacuum conditions, refrigeration oil will not boil at ambient temperatures.

Re: System low on refrigerant won't take charge

Make sure your can of R134a does not contain ANY sealer !!!

Guess #1: your charging hose fitting is not depressing your low side valve

Guess #2: try misting the condenser in front of car with a garden hose/water while you try to add refrigerant.

Re: 2006 denali cooling problem

I sure hope that the can you put in was only R134a and did not contain ANY sealer, that could kill the system. I have a 2005 Denali. Sounds to me like you have a refrigerant leak, need to have a real AC shop look at this and measure the refrigerant in it by weight. And pinpoint and/or fix the leak. ...

Re: Very high High Side Pressure

How's the fan clutch? All the fan shrouding in place? Did you try misting the condenser or a floor fan in front of the van to see if pressure drops?

Re: Strange compressor behavior Volvo V50

This is a Volvo V50 that was low on refrigerant. How do you know this, did you weight the recovered refrigerant?? Compressor clutch kicks in and spins the compressor but no work is done. High and low are not moving at all. Not the slightest bit. What could be the problem here? Guesses might include...

Re: R12 hoses with R134 Adapters

Post good photos of the ends. I bought adapters about 15 years ago, and they've worked fine. Why not use loaner R134a gauge set from Autozone? I used such set last year when 100 miles away from home when I developed a pinhole in a rubber line and had to replace that. Remember: use NO SEALERS, just p...

Re: Bad clutch or what?

I have a 2003 Chevy Tahoe. Air only blows hot. I need to know if the clutch is bad. Here’s what I’ve done to troubleshoot: Checked voltage with everything running at clutch and voltage reads 13.8volts, but clutch wont engage. Does this gaurantee my clutch is bad since I have 13.8v when ac is on hig...

Re: New compressor. Not cooling well.

What vehicle, what model, what year?

Didn't "buddy" know how to remove an AC belt?

Your low side pressures are quite high.

Re: Compressor/mag clutch noise - death rattle sound?

Three years ago the AC on our 2005 Yukon started breaking its small AC belt (separate from the main serpentine belt). After replacing the belt a couple of times, read that low position of compressor on engine caused slugging, and caused belt breakage. And AC worked great until the belt would break, ...
