The schrader valve on the low side port of my 2008 Chrysler Town and Country failed---pulled into the garage and could hear a hissing sound. Investigated it and it was the schrader valve. Otherwise, the system has worked fine, and has no issues.
Anyway, I purchased a new schrader valve, and installed it. Vacuumed the system for 1 hour (why not?) with my harbor freight 2.5 cfm vacuum pump. System held vacuum for 20 minutes after I vacuumed it .
So, my van has dual air conditioning---front and back.
The system label says says 29 oz single or 40.5 dual (see below).
Rather than use my manifold gauges, I disconnected them, and just attached a hose to the low side, since I didn't want to mess it up. Anyway, I added 2 12oz cans of 134a, and the system started blowing cold (24 oz total). However, I'm nervous about adding more refrigerant. My gauge said after the 2 cans that the low side as at 50. I'm confused, because I was expecting to add 1 1/2 cans additional. But it is at the max on the gauge--50 psi. I don't want to put not enough R-134a in. System blows cool (it is hot outside, and I haven't taken it on a long drive yet).
Advice? Thoughts?
