What are the differences between R134A and R12 units. I am totally in the dark on this. I put this in the lounge because it is not Bonneville related. My parents just bought a 95 G20 van and it said something about 134A under the hood. Any help would be appreciated.
r 134 prices are about to rise...i heard that Dupont isn't making it anymore...for waht reason i don't know..but it'* already doubled down here...both us and Autozone are going up..it'* expected to be 15 bucks by april!!
