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...

Re: Motor home ac

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.

Re: Best Compressor For R12 In Diesel Pusher

Good question bohica, as a 1995 would've been factory R134a, I didn't catch that.

Re: Best Compressor For R12 In Diesel Pusher

Most 507s are set up for R134. Will one of these work if I just swap out the oil or are there other differences? The replacement Sanden in my 1988 Mazda truck came with PAG oil in it, I needed R-12 mineral type oil. So I drained out the PAG oil, added about 4 oz. R-12 mineral type oil, turned the c...

Re: New to forum, looking for input on where to introduce PAG oil

Understand about the confusion. My one and only experience with a GM dealer was finding out that they "have no idea what was wrong with your sunroof not able to close" on our 2005 Yukon a few years ago, then being reluctant to refund my money ($230), after we had agreed that I'd pay for a ...

Re: New to forum, looking for input on where to introduce PAG oil

I believe GM may have used PAG150 at one point but reverted to PAG46 later OR a universal PAG for GM which may be PAG100 but I cannot get any solid info. I don't want to destroy my new ACDELCO V7 compressor w/ the wrong viscosity oil. Dave Dave - I definitely understand what you say about conflicti...

Re: New to forum, looking for input on where to introduce PAG oil

You can add the oil anywhere, it will distribute itself once in operation. If you pour into the compressor directly, be sure to rotate the compressor (inside nut or bolt of the compressor clutch assembly) at least 10 full revolutions before you start the evacuation and charge steps. Also a good time...
