Well, I had today off so I washed
China for the first time since right before Sunny's GTG last year!
I also evacuated the system of R134a since it was a tad low after about 3 years and wasn't cooling below 70 degrees or so. I bought some Envirosafe last year just for this car, so this evening I decided to go ahead with it. Since Envirosafe doesn't turn acidic from moisture it is a fairly easy process.
I vented the R134a, replaced the inner Schrader valve, installed a new R134a port on the low side. With a syringe I squirted in about 4ozs of Pag-150 into the low port, then turned the compressor about 20 times.
Installed the AC gauges from Autozone, hooked up the vac pump from Autozone, and pulled a vac for an hour. I guess I didn't need to, but I just couldn't hardly stand "not" doing it.
Then I pumped in 2 cans of Envirosafe. Temp was about 95 degrees in the garage. Low side at a high idle was about 26 and high side was about 260.
Went driving around this evening and got vent temps down to 41 degrees.
We'll see how it does during the heat of the day.......
