My El Camino normally has GM top quality A/C. 38 degrees in 110+ temps on max blow. Back in the 80s, AC Delco made the R-4 compressors, and they just worked for years. Now they all come ffrom China, and 12 months is about it. So I switched to a Sanden compressor last year. That was a pain in the butt. It was down on refrigerant once again this spring. %#(*!*^^ and profanity!

I went up to a buddies place that has a sniffer. The 4 Schrader valves all had a slow leak had a small leak, and I put in new O-rings in the caps to hopefully fix that. Then I went to the high - low pressure switch that screws onto the accumulator. The sniffer was squealing like a little girl, or a stuck pig. OK, remove that switch that has a Schrader valve on the accumulator, and replace that o-ring, and tighten until I was afraid the plastic switch would break.

I hosed it all down with carb cleaner, and in a few days, I will do the sniff test again.

Seek and destroy, um make that seek and repair! I don't want to have to top it off again!
