The AC high pressure valve is leaking on my 98 catera. I was going to add some refrigerant withac gauge line (red) and when I took the cap off on high side I could hear a hissing sound and took a close look at it and realized it does not have a valve like the low side valve. The high side has a rubber cap / seal in the valve and that's where the refrigerant is leaking from.
My question now, is it possible just to replace the high side valve? I saw some ac valve on Rockauto.com but was not sure if that was the right part?
Thanks for the post guys this is a big help. Had a shop charge mine he said he replace the Schrader valve for fee, I thought he was full of Bull. but I know now
My other catera is leaking there too.Thanks
