Refrigerant Type: 134A
Hey guys, after adding a little 134 on this car I noticed that when I removed my QD from the high line gas was coming out. Didn't seem at 200-250psi but it was clearly coming out. Does a cap w/a O-ring seal this thing?
yes
-------------------------
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......
Theres no Schrader valve in the high side port?
Only the cap w/washer is the only seal?
anybody? Hard to believe theres no Schrader valve in a high side port

On GM cars with 'replaceable" high side ports, the shrader valve is replaced with a "teflon" ball, but it seals as a shrader valve would. I usually change them with an ac service because of having them stick open. This pic is from a Ford, but should look the same inside
To change the "shrader valve" you would change the whole port..
