Recharged the A/C yesterday using my Harbor Freight compressed-air-powered vacuum pump and A/C Manifold Gauge set.

I still had several bottles of ES-12a left over from the last time I charged my silver RX-7's A/C (that must have been like 4 years ago) and I had good results with that stuff so I used it again.

The first thing I did was pull a vacuum on the system to check for leaks. I let it sit for over half an hour and found it held just fine (no leaks!) and then released the vacuum (since you're not supposed to charge with a vacuum when using ES-12a).

I used about a can & 1/2 (and they are 6oz cans) to charge the system. At idle, this gave me about 45psi on the low side and 175 on the high side. The high side seems a little low, but that's expected when using this stuff, as I understand.

Anyway it blows nice and cold now. Haven't done a temp test yet - just glad it's blowing cold air with FL summer heat coming...
