My name is Felix from Frankfurt/Germany, new to this forum. Hope you are all doing well. I registered to get some help with the AC system in my car. The car is a 1989 Chevrolet Caprice Classic LS Brougham, 45k miles, stock 305 TBI. Welcome from the USA. Background info: -preowner converted the AC i...

IIRC (it has been a while), the answer is yes, as long as the threads are the same. The superheat switch is part of a fail-safe circuit for the A6 in your application. If the back of the compressor gets too hot, the SH switch senses that, closes, and grounds the hot wire to the clutch, causing the (...

So far no luck in getting any replacement for that line, so I am wondering about repair. I found a short piece of hardline with a female o-ring fitting like this: (photo removed) I would think that cutting off the old end and replacing with the above should be easy, but how best to splice this?

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...
