R12 to r134 conversion

enviro-safe and alternatives

as for being more flammable than r-12 and r-134a it's true. but all new cars will be using a new coolant 1234yf which is a greener solution, but much more flammable than any of the old refrigerants or the alternate refrigerants. so if you want to use durocool or freeze i would say go for it..
also whenever changing the type of coolant, drain all of the oil out of the system, replace the separator/desiccant canister, fill with the recommended oil in the amount specified. and your system should work.
the alternate coolants usually perform better than r-12 or 134a. i can't vouch for the new 1234yf. too new to require service by anyone but warranty issues...
be prepared for sticker shock if you need your 1234yf system worked on, the a/c coolant is very expensive... currently around $50/8 oz can...

I have the compressor that was in the mustang, how would I go about testing it?

if you have it off the truck or car put your fingers on the two ports where the hose block connects, turn it by hand you should be able to feel it pushing air in and out underneath your fingertips that usually indicates it's ok

Thanks for the info, it's sitting under the work bench with the rest of the growing pile of parts. Lol
I live in Las Vegas so a/c is a must have with this vehicle.

Duracool is an excellent choice. I have had it in all of my cars for over 20 years. My Bronco II blows 35 degrees at the main vent sitting still at fast idle at 90 degree outside temps. The cans dispense the same as R134 does. You use less Duracool to charge the system. They advertise lower head pressures as well.

I'll look into the duracool.
