A/C Valve Problem
|
Sign In
|
|
Year: 1992
Make: Chevrolet
Model: Cavalier
Engine Size: 2.2L
While refilling my car with freon, the R-134 valve crossthreaded onto the R-12 valve. Now the R-12 valve is constantly leaking freon back out. What parts do I need to replace and fix this problem? Thanks in advance for any help.

The nature of an A/C system is such that untrained people shouldn't attempt to service them. My best advice at this point is to take the car to a reputable shop. Perhaps the service port can be saved, otherwise it will need to have the part with the port replaced.

Be fast - get the 134a fitting off! There is a shrader valve in the original that may need a slight tightening. You can get a new fitting for 134a one by one. Some are too close and hit the original shrader (like a tire valve) and need a special tool to back them off of the adaptor. You probably didn't wreck the car's threads as those adaptors are not as strong.
At any rate get if off there! It's now junk. They come with thread lock, so it could give you a hard time. Grease the next one to stop that. Good luck,

I'm not into Government Regulations for the most part. But stuff for A/C is sold everwhere with little warnings or that the trade is a TRADE unto itself and takes a lot of know how/training. We can help with stuff here but this is a huge topic - usually best left to the pros. Careful out there folks. When in doubt - don't!!
I'll go out on a limb here and say I have a web site for A/C, that is strong with selling e-books, but also has a forum for tough A/C problems, now just visited by pros but all are welcome... Requires sign up, I moderate there to keep it a family friendly place.
HTTP://TomGreenleaf.AutoACsystems.com Come visit if you feel like it. It does NOT compete or replace this site in any way. Click on the "Cool Zone" if you want to check out it's forum. By all means come back here, where folks can deal with a wide spectrum of car questions, Best,
