Is R12 still legal in Canada?

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 ...

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.

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

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...

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 ...

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...

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...

2012 Mustang base 3.7L V-6 convertible. Retrofitted Ford heater/evap core with 4Seasons evap core that I assume ships without any oil inside. I also replaced the accumulator as system has been vented for a while. I could not find much useful guidance on adding oil for Mustang component replacement ...

Are you saying that all the contamination is at last contained inside the dryer? In other words I don't need to worry about the expansion valve or evaporator needing replacement? I believe most driers have a screen that would trap particles. I didn't touch the expansion valve or evaporator when I r...
