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...

JohnHere, Thank you for your reply.. Just got back from my trip and will be working more on this shortly. Would love to have a simple "old Fashioned" way to do it and have a couple questions on what you wrote. Will ask those once I can phrase them clearly. First I have to re-evacuate my s...

I don't remember anymore, but did you replace the pressure sensor on the evaporator tube? It should have a Schrader valve behind it, eliminating the need to recover the system beforehand.

So the only way I can flush the evaporator (behind the dash) is flushing through the lines that are connected to the condensor and compressor. I just disconnect those and cycle through the lines, evaporator and expansion valve. If I remove the expansion valve it would allow the flush material to ge...

The A/C system does not have the correct amount of refrigerant in it. Just an ounce or two either way in such a small-capacity system will cause problems. At this point, we don't know precisely how much refrigerant the system contains...and the amount MUST be precise.
