Re: Ac low pressure reading

My wife lost A/C in the Kenworth she was driving for work (water truck at a big construction project) and I replaced a couple of bad O-rings, pulled a vacuum and re-charged it for her with the little cans to get her back working in A/C. It can be a pain with those little cans but it is doable. I did...

Re: 03 Chevy Suburban Fresh Charge and still not cold

Usually the magnet just doesn't have enough strength to pull the clutch in but if you give it a little nudge it'll suck it in the rest of the way and...

Help identifying an odd fitting

Can someone help me identify this fitting? It’s on a 93 Saturn that came from the factory with R12 but it appears someone did a conversion. My low side coupler snaps into place easily and when I first saw the threads on the outside of this I though maybe they hadn’t converted the high side fitting f...
