Engine Size: 3.8
Refrigerant Type: 134
I have a leak out of the high side service port. There's no valve visible inside, just a black rubber plug. How is that supposed to work?
A good quality cap with a good rubber insert will seal that port- as designed to- if the port is just bubbling tad-
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
That's the easy way
I'm going to be opening the system to replace the compressor anyway, so I'l like to do it the "right" way. Is there one?
The ones with the rubber ball or plug, you'd have to replace the whole fitting. It unscrews from the tapped part welded to the line.
ac delco # 15-5438 GM# 52458184 i typically stock around 5 to 10 of these at any given time ! I replace them almost always when i have a system open that uses them !! nothing worse than finishing a job and taking the highside off (after its equalized) and having 1 of those things to leak!!
