Agree with Tim - that's good vent temperature.

Re: New Motorcraft compressor, clutch wouldn't turn by hand, squealed after installation

If my vehicle, just to learn more, (1) I'd pull the belt off the compressor and try turning the compressor with a wrench. (2) I'd jump the compressor clutch with 12 volt positive wire and see if the AC clutch engaged each time. I would guess that it might be possible to get oil on an AC clutch surfa...

Re: 2004 Jeep Grand Cherokee...

Hi guys... Was just informed the car passed the vacuum test and there’s no visible refrigerant leak to the naked eye. I was given two scenarios...either there’s a minor leak that can’t be seen as I said (although I’m unsure how likely that is - hence why I am here) OR The mechanic who did the compr...

Re: 2004 Jeep Grand Cherokee...

To me, your story sounds like a refrigerant leak from Day One. Your parts might have been replaced when not faulty. A dirty evaporator (leaves) can be cleaned without dismantling or replacing it. Good-working AC which gets worse over time typically means refrigerant is lost; a shop can evacuate and ...

Agree; test the gauge with the valves to the vehicle blocked or shut off, and pull a vacuum then.

Re: shelf life opened DEC pag 100

My opinion as a degreed chemist? If the bottle was sealed, then the only moisture that the oil can absorb is the humidity from the headspace of the container, not like it would continue to absorb water as if it had been left over. How about the oil itself? Well, the refrigeration oil in my 1998 Fron...

Re: Trouble in paradise. Thanks in advance!

I attached the R134a to my manifold gauges, purged the air out of the yellow line, closed the can and started the car with the A/C on. Hmmm - here's what I do (wear safety glasses): After evacuation step and checking to ensure that vacuum holds, I attach the refrigerant can to my manifold gauges, p...
