AC Schrader Valves

Not sure which years have which. Mine are '00 and '02.

Correction - the rubber check ball is actually on the low side of mine. I had to replace this line yesterday myself.

If you are gonna say that, then say what year,

What year.

It's in this post:

What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I never posted pics of the water pump and AC compressor work I did on the 2007 so I can understand if y’all thought I was talking smack. Here ya go!

I'd be surprised if that would fit the low side on the 07-14's. I know it's tight as hell back there I can barely get the gauges hose connected in there. Neat tool though.

My truck (info in sig) had a check ball in the high side and a Schrader in the low side. When I replaced my AC compressor and drier in March, I replaced the high side service port with Dorman 800-955 since it uses a Schrader valve. Based on my reading online (and my personal experience), the check ball is more prone to leaking than a Schrader.
