On my recent trip up to Maine and Canada we had many long stretches of driving in 90 and 100 degree heat while going through Arkansas, Tennessee, Kentucky and other states. I keep a little analog AC service techs type thermometer is the tiny little vent of an 85 Carrera AC vent on the drivers side. It was at 40 degrees many times. After several hours I would get cold when the sun was coming in on my wife. She had me keep the AC at COLD and I was honestly cold when it was high 90s outside. I had to divert the vents from blowing on me. We had a couple of 850 mile days. The AC was just fantastic.
When I pulled the vacuum last time I used belts & suspenders and went over total overkill. I pulled a vacuum for several hours and shut the pump off and let it sit overnight. Start the next morning and pressurize with nitrogen to 90 PSI, pull a vacuum for hours then pressurize with nitrogen. Pull a vacuum and let it sit overnight. I changed the oil on the compressor and let er rip for two hours, then charged up. No shop would ever go that far and I suspect it was overkill, but the AC is working better this time than ever before.
