Anyways, I have some gauges and I'm charging the Freon level. I had the compressor off and replaced it and the dryer. I also ordered a new expansion valve but when I saw where it was (Behind the brake booster) it scared me. I pulled a 29"HG vac and it held just fine. Anyways, I started charging it. Here are my numbers:
Car not running:
Low Side-Pegged
High Side-160psi or so
Car Running at idle:
Low Side-110psi
High Side-Pegged until the compressor shuts off. I jumpered the low pressure/level switch on the dryer a moment and the compressor stays on. With out it jumpered it cuts on and off ever 10 seconds or so.
Lastly when the car turns off Low and High should equalize. Am I right??
Any ideas what's the matter here? My guess is maybe the expansion valve.

hey, are you still alive?
did your a/c system explode? let us know how much freon you put in that thing. with those pressures, you have to be pumping liquid in the compressor, so it's gonna be shot if you aren't careful. reclaim all the freon in your system, and weigh it, I be you have like 8 lbs in there. |
