I purchased a couple of new caps at NAPA today. I'm guessing they should be installed until they are snug, and then tighten just a bit more. But maybe someone can let me know how much force is needed when installing the caps in order to avoid refrigerant escaping. The caps are usually plastic, so d...

Thanks, Tim. I thought that might be the reason.

And the three remaining photos.

Cusser, Here are two out of the five photos that failed to post with my earlier comments. Might have been too many at once. Three more to go

Cusser, I believe that auto manufacturers make their caps with proprietary threads and size differences inside because I've had the same problem as you with replacements not threading on. Why they do that is anyone's guess. One would think that the caps would be standard across the industry with onl...

how do I know if the system is working properly? You don't...not without the proper tools and know-how. As Tim mentioned, those Recharge Kits with a single color-coded gauge, available at the Big Box Stores and some auto parts suppliers, can't tell you much of anything without seeing specific press...

1. Regarding the Nylog Blue, I'm assuming the old Nylog Blue should be removed and reapplied each time the AC is serviced. If so, is there product to remove the old Nylog Blue? You could just wipe it off each time a connection is opened (hopefully, you won't be doing that very often :mrgreen: ) and...

If you recover the refrigerant or have the shop do it, and then seal the open ends of the lines that you remove from the condenser, and the condenser itself, driving the car as you describe won't ruin the compressor. The compressor won't engage anyway with no refrigerant in the system. Pulling the f...

I don't see any obvious reasons why your setup wouldn't work. Charge the system to the factory specifications and see how it performs.

The original specs for your Jeep are 24 ounces net weight of R-134a, and 5.75 fluid ounces of PAG-46, unless the Sanden compressor requires more oil than that.

If the caps aren't cracked or broken and the inner seals are intact, chances are you can continue to use them. I had a 1994 Toyota Camry Wagon, bought new, that up until a year ago had the original caps that never leaked. Take a look at the inner seals using a magnifying glass and a strong light. If...
