Drive the car on a hot day and report back It got into the low 90's today (like 91°-92°) and it cooled like a champ. So far very pleased with the results. Assuming there isn't some microscopic leak that isn't showing itself yet, I think this one is licked. Thank you guys for all of your help and pa...

Why did you replace the comp? Did the previous one fail? This is important. Drive the car on a hot day and report back It didn't crater, but there were large amounts of oil and dye all over the bottom of the compressor. I could add refrigerant and it would cool, but not long. I posted the pressures...

I didn’t do anything with oil. The compressor came with the proper amount of oil already in it.

Well, shows what know...or don’t know. I thought those pressures were supposed to be higher. The compressor came with the oil pre-filled from the manufacturer. The system calls for 18oz. of refrigerant according to what JohnHere posted. I may have slightly misjudged how much I put in. I’m probably c...

Okay, system charged. The ambient temp when I started was about 81°, but has now dropped to about 78°-79°. I added maybe a little over 1.5 cans of refrigerant using provided directions in this thread. Best reading at center vent @1500 RPM was 41°/42°. Pressures don't seem right. Pressures as follows...

Yes, sounds about right, good job. Be careful when you switch your yellow hose from vac to charge that you do not introduce any air!! Be sure you bleed all your hoses of air. You are probably using cans even tho that is not the preferred way. For the first can, turn it upside down and thus rapidly ...

IMG_6383.jpg And we have liftoff... Low and high port schraeder valves replaced, fresh oil in the pump and back under vacuum. Went to 28 inHg almost immediately. I actually tapped on the gauge a couple of times and it went to 30 inHG. The plan is to let it vacuum for an hour or so, then let it sit ...

All oft he help and guidance has been greatly appreciated.

Back off to the auto parts. The schraeder valves in the service port repair kit that I purchased are much, much smaller than the one I pulled out of the service port. Hoping I can find one that fits.

Typo? I think you must have meant 28 InHg and not 20 InHg. I can't explain why the reading would increase slightly overnight. Sometimes, a system can hold vacuum indefinitely but leak under pressure, and vice-versa. So because it held vacuum overnight is no assurance that it won't leak after chargi...

The saga continues... The manifold gauges were a loaner set as well. I took the pump back to AutoZone and got a different one from Oreilly's. Same result. I started looking at the o-rings in the hoses and they were pretty gnarly. I ended up picking up a brand new set of gauges. Full disclosure, they...
