Re: AC Stopped Cooling
By hot air do you mean ambient air? If so, the system could be low on refrigerant due to slight leakage over the years from the compressor shaft seal. Low refrigerant would be the first thing to check because that's the most common problem. Don't be tempted to try "topping it up." Have the...

Re: Should I try control valve or just replace compressor
Interesting dilemma. It sounds like the compressor manufacturer is telling us that it could use either viscosity. Because your car calls for 9 fluid ounces of PAG-150, I suggest draining the PAG-46 and going with the PAG-150, plus one ounce more than supplied in the included bottle.

Re: '66 Oldsmobile problems
It could be the compressor. Is it the original?
What refrigerant did it have when it lost its entire charge?

Re: R134a mixed with pag and poe
Would I be wrong to guess that maybe 5ml of oil was sucked out or would it be more in your honest opinion? Hard to say. It probably was a mixture of refrigerant, oil, and dye that you saw in the sight glass. In any event, 3 seconds worth has to be a very small amount. Only 5 ml of oil lost from the...

Re: Fan does not bring down high head pressure
If I recall correctly, I believe this car has a variable-displacement compressor with an electronic control valve and is direct drive (no clutch). It's possible that the control valve failed and is causing the pressure irregularities and poor performance. Consider changing the control valve first be...

Re: R134a mixed with pag and poe
Hi all, new to this forum. Just have a quick question. I had R134a stored in my recovery tank that’s previously been in systems using pag46 oils. I was recovering ac out of my 2014 Honda Accord Hybrid which uses nd-11 Poe oil, which I realized after recovering all the refrigerant into my tank conta...

Re: R134a mixed with pag and poe
Did you use an automotive RRR machine to recover the refrigerant? The reason I ask is because RRR machines typically collect any recovered oil in a separate graduated container so that the technician can add back into the system the same amount that came out. The recovered oil normally doesn't mix w...

Re: Fan does not bring down high head pressure
Both of the pressures are too high. I'm surprised you get any cooling with a low side of 40-45 PSI. A reading of ~45 PSI means an evaporator temperature of ~50°F and center vent temperatures even higher than that--hardly adequate for comfort on a hot day. Try misting the condenser with a garden hose...
