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.

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...

Added 4 12oz cans r134, pressures are 20 low, and 170 high, ambient temp 75, It seems to cool OK, I can see bubbles in sight glass. Does someone know how much refrigerant this system holds? I think the upper one was colder, but not a lot. The motor home is at a storage lot, so I can't just run out ...

Re: Changing a Desiccant bag

What type of vehicle? I'm not a pro, but haven't even heard of a desiccant bag replacement. If new drier is a available, I'd go that route.
