Here's the numbers Gilly


I hitched up the gauges to the system and here's what I got. With engine at operating temps and compressor on I had 160 psi on the high side and about 20psi on the low side. After shutting off the compressor I had about 140 psi on the high side and about 40 psi on the low side. The temp outside was about 90-91F Any ideas what to look at? The suction side seems a bit low, any thoughts on this? Could I still be low on freon even if the sight glass shows very little bubbles? I was going to tap on the expansion valve but didn't find it where I thought it should be, guess it's well hid. The temps on the compressor pipe intake and outlet. Hot and luke warm.

Any suggestions on the problem area?
