R-134A charge port fix in a pinch

[billsc30]

If you have a leaking valve core in the liquid or suction sides of your a/c system with the R134A system, A quick fix to keep from losing the refrigerant is to use a 5/16-24 x1/4 allen set screw with some teflon tape. The plastic caps are ok if the seal is still good , but more often than not the threads are either stripped or the seal is split. I did this on my truck and it worked like a charm. I just wish i wasn't thinking in terms of a refrigerator when i charged it. Now i have a coil temp of 26f and a discharge temp at the vent of 30f . I'm driving a meat locker! Just thought I'd share something that worked well for me.
