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...

Re: How much oil for 2012 Mustang evap

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 ...

Re: 07 Sonata 2.4L 4cyl, ac not cooling anymore.

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...

Re: 07 Sonata 2.4L 4cyl, ac not cooling anymore.

days before it quit I could hear a metallic crushing noise associated with the a/c been turned on, and would go away when turn off (meanwhile the a/c was still blowing cold). Yes, that sounds like a bad compressor to me (do not run it further). I'd disconnect the compressor wire if you decide to wa...

Agree in your case, fittings and potential refrigeration oil residue.
