Re: Walmart out of r134a refrigerant in Kentucky

I don't think Walmart is getting out of the refrigerant business of selling the small cans. But with R-1234yf currently selling for about six times that of R-134a (per pound), it looks like the market for the newer refrigerant is going to be much smaller among DIY-ers. To buy any refrigerant in bulk...

Re: Compressor Won’t Shut Off, Freezing Evaporator

After the daily ambient temperatures rise in your area to 80°F and above, keep an eye on it after running it for a while. If you notice reduced air flow together with poor cooling, the evaporator has iced-up again due to a refrigerant leak someplace. Given the vehicle's age and mileage, the leak cou...

Re: line size

The smaller the hose ID, the greater the velocity and pressure. So it might or might not work if you go with a #8 hose instead of the called-for #6 hose. Worse comes to worst, you'll have to plumb it over if it doesn't work. Another possibility that comes to mind is to use a #6 hose all the way from...

Re: line size

Unless I'm misunderstanding, I think you're mixing terminology a bit. Do you mean a #10 from the evaporator to the accumulator, and a #8 from the accumulator to to the compressor (on the LP side)? Also, the #6 from the condenser to the R/D, and then from the R/D to the evaporator (on the HP side), s...

Re: Compressor Won’t Shut Off, Freezing Evaporator

Refrigerant loss probably is responsible for the evaporator freezing-up and blocking airflow on your 18-year-old Jeep. Before doing anything else, have a professional A/C shop charge the correct amount of refrigerant into the system, as suggested earlier, by recovering and noting what's in there now...

Re: Seltec TM-21 Shaft Seal

A couple of options come to mind. Consult with Tim at ACKITS.com, this Forum's sponsor, who's very knowledgeable about such questions. Or, consider replacing the compressor assembly, especially if it has a lot of miles on it. ACKITS.com can help with a new compressor at the best price. What make, mo...

Re: Is it possible to fix this a,c pipe

Yes, £800 (approximately $1,000 USD) is expensive. But your pictured lines with the chewed-up Springlock connection have twists and turns, and an apparent crimp besides, making a fix unlikely. You'll be better off having the shop handle it from start to finish. They will install new lines and whatev...

Re: C2 Corvette parts search

I didn't realize at first that your '66 Corvette has an STV, similar to the one I had years ago on a new '62 Impala/283/Powerglide with factory A/C. The STV was hidden under the right-front fender in the engine bay and operated manually via a cable controlled by a horizontal slider on the lower-cent...

Re: C2 Corvette parts search

Are you going to keep it R-12, or do you intend to convert it to R-134a? if the latter, you'll need to re-calibrate your original POA (STV) valve to the "newer" refrigerant. If your original POA valve is intact and rebuildable, why replace it? Several professional rebuilders with an Intern...

Re: Newbie, installing "custom" system

The ATCO fittings at 7.95 mm OD seem about right. The ones that measure as small as 7.6 mm appear to be out of spec to me.
