Re: Old school AC system compressor burned out
Servicing a VIR assembly is not difficult. Remove it from the car. Clean it before you open it. Service kit will have the O rings and the desicant bag. A clean workspace is a good idea. You may find that the old desicant had an issue with the 134a. Clean everything. Various GM A6 compressors have ha...

Re: Installing Aftermarket AC in a Dodge Van
this guy is tenacious. I figured he would be back.
Best of luck with the BMW, and start a thread for it if you need help.

Re: 1993 Jeep Cherokee A/C Performance Issues
The original condenser was a Serpentine design that worked well. If it was replaced with an aftermarket part of a different type, it is hard to say if the condenser is up to the job. Jeep went several years where they could not make up their mind on fans. I believe your 1993 should have an engine dr...

Re: Installing Aftermarket AC in a Dodge Van
So how about some pressures? Engine RPM above 1500, evaporator fan on highest speed. Hold that for 90 seconds to stabilize and read the pressures while the engine RPM is above 1500. Dragging the hot air from the top edge of the windshield across the evaporator is not going to provide the best vent t...

Re: System on Fire Engine
I guess the question is, how is the cooling capacity with 47f air? Large volumes of 47f air can cool pretty well. I would wonder if the TXV has a poor CV match for the Evaporator size, causing the low discharge pressure, but I have a sample size of one here. No like I can compare the system to anoth...

Re: System on Fire Engine
High side numbers are looking pretty solid. It is moving some heat.
Low side is not terrible, the 14 psi and 47f discharge are a little harder to reconcile. Is this an E-One unit? Might be within their parameters.

Re: System on Fire Engine
Well, since you have recovered it, check the TXV inlet. Do you recall if the TXV had an inlet screen?
TM 31 compressor has a lot of volume, it is possible for those pressures to exist with high enough ambient.

Re: System on Fire Engine
Does not sound reasonable for just a low charge. What sort of system? CCOT or TXV?
I recall you had a truck with a half charge of refrigerant and a gallon of oil once. Any chance the same guy was there?

Re: 2003 MB E320 W210 R/D missing
"Bohica described the compressor as direct drive, always spinning and hence should be replaced because the system is open and the compressor will gulp in air. But... Turns out that this E320 uses a clutched AC. The compressor is not spinning continuously." Had YOU posted the correct model ...

Re: 2003 MB E320 W210 R/D missing
That car has the direct drive compressor. No clutch. An electrically operated control valve de-strokes the pistons wen cooling is not needed. So it has been turning since the day the R/D was cut out of the system. Hard to say what the compressor condition is at this point. There is a shear ring on a...
