AC Charging technique

[Tuesdak]

What was the pressure measured from? Gauge or ECM data readout?

If you mean the high pressure 400+ it came from my MM3

Up to 435psi is within spec.

Mine never dumped Refrigerant, even severely overcharged.
Sanden compressor, not the Hallal.

Hey Ozy

When the pressure starts rising it rises fast. It went over 450 today at an ambient temperature around 95F. Standard Operating procedure from hear on out is watch the pressure for the 1st 5 minutes.

Yeah, I was just wondering about the buzz for the AC pressure that came up lately.
I use my truck for 11 years straight now and never gave a thought to the AC, it just does it's job and that's it.
From -40F to 125F it has seen all and it always delivered, no matter what.
Only thing that was needed was a refill last year, first time since I bought it.

you must be living right.

Maybe enough other problems to watch for, can't afford another one to watch out for.
