Problem is finding somewhere to buy it anymore. If you have your card, you can still buy canisters of R-12 behind the counter at O'Reilly (they lock it up in the back room). Also, I've been hearing that R134a is about to go on the "tax it out of existence list" and will be replaced (this year?) with 1234EZ which I think is made by DuPont. 70 Roadrunner convt. street car 440+6, NOS, 4-spd, SS springs '96 Mustang GT convt. street car '04 4.6 SOHC, NOS, auto, lowered "Officer, that button is for short on-ramps"

It doesn't cool as well as it did with R12. The work was done nearly 15 years ago and I've been all over it numerous times. It just doesn't do the job as well. I thought about going to 134 on the Imperial but the 12 cools much better than 134 in my truck. I have no interest in messing with that. I think in Orange County it's illegal for you to even take that picture No comment..

Some also want you to change all the hoses to barrier (liner) type, since R-134a leaks from the old hoses at a higher rate than R-12. You're already going to have both ends disconnected to change the o-rings anyway... I would replace the hoses with barrier anyway. If you have any leaks, chances are it is from the old rubber hoses anyway. The second most common leak point is the compressor drive shaft. 2014 Ram 1500 Laramie, 73 Cuda Previous mopars: 62 Valiant, 65 Fury III, 68 Fury III, 72 Satellite, 74 Satellite, 89 Acclaim, 98 Caravan, 2003 Durango Only previous Non-Mopar: Schwinn Tornado
