Re: 1966 Oldsmobile A/C

What is puzzling to me is that the hose from the expansion valve going into the evaporator is just mildly cool. But from the middle of the POA downstream, it has frost forming around it, as if the POA was acting as an expansion valve. I supposed it could be clogged internally in some way, but it see...

And why is the POA set to 30 psi?

.

R152A as a R12 alternative. I was under the impression that 30 PSI was the correct pressure for R12.

Thanks.

Re: 1966 Oldsmobile A/C

Hello,
By rebuild, I should have said disassembly, cleaning and resealing. Nothing inside looked worn out.
Thanks.

Re: 1966 Oldsmobile A/C

It does seem very low to me too. But if the system called for 48oz of R12, it is already filled to 60% of that in R152A. I don't want to overcharge it.

Thanks.

1966 Oldsmobile A/C

Hello, I've been working to revive the A/C in my '66 Toronado. I rebuilt the A6 compressor, had the hoses remade, replaced all o-rings, dryer, flushed the system, added 10 oz of PAG oil150 and 30oz of R152a (manual called for 4 lbs of R12, so 60% of that). I had tested the POA with compressed air an...

That would be ideal, but I am concerned about long term availability of R12.
Thanks.

1966 Oldsmobile A/C

Hello, I'm in the process of reviving the A/C in my 1966 Toronado. I rebuilt the A6 compressor, I'm having all hoses rebuilt and will be flushing the evaporator and condenser. What gas do you recommend? R134A, R152A? Propane/Isobutane? I have never dealt with a system with a POA. I plan on rigging m...

Re: 1963 Jeep A/C

I did get a chance to measure some temperatures. With the fan on HIGH and windows down in a 88F day, 55F vent temperature. After the cab has cooled down and the fan is on LOW, 40F or lower (remember, this system only uses inside air). I'm quite happy with this performance.
Thank you.

Idle. I will try to get more data early next week. It's supposed to get hot then.
Thank you.

Re: 1963 Jeep A/C

40 PSI low, 285 PSI high. I don't have a thermometer handy, but I would guess low 50s/high 40s. Remember this unit does not take air from the outside.
Thanks.
