7 oz is all that would go in. It was 85 degrees out, so system pressure would be 90 or so wouldn't it? Should try to run at least a little.

Wire setup for checking continuity of the coil was pretty sketchy.

2005 Saturn Vue. System was empty when it arrived. It had signs of dye around the high and low connections. No bubbles at connections when I applied nitrogen to the system. Can't find dye anywhere. micron gauge starts to rise when the vacuum pump is turned off. Added dye and 1/4 oz of oil. Vacuumed ...

Thanks for helping me understand that!

The system moves a lot of air and at 47 vent temp, it does a good job of keeping us cool.

Connections for the gauges are on the compressor. I would call it a long run of hose from there to the evaporator. It’s a cab over and the evaporator is mounted to the roof on the inside of the cab.

I wasn’t able too find a leak.

It is an E1.

Didn’t find any debris at the expansion block. Vacuumed for 10 minutes and it went down to 560 microns. Valved off the pump and it continued down to 530. It stayed at 530 for 10 minutes with no rise. Turned the pump back on and ran it for an hour total and it went to 510. Charged it with 5.5 lbs of ...

I’ll work on it again Sunday. The evap case is already off so we can look for dye. It won’t be much work to check the inlet.

There is a chance, I’m the only one that has worked on it since it was bought in 2003. I’ve done quite a bit off work to it. The most recent was when it had similar symptoms in June of 2018. Changed the expansion valve and dryer. It’s worked until just recently. Has dye in it. No obvious leaks noted ...

This is a truck at work. System reported to not be cooling. Recovered the refrigerant. It had 1.5 lbs. System capacity on the drivers door says 5.5 lbs. low pressure was 2 high side was 200 with the high idle in. Does this point to a leak with a restriction in the system or would those numbers be ...
