Post subject:  V2 with R134

Can I use a Chrysler V2 compressor with R134? I agree with everyone who may say that R12 is OK and there's plenty of it. But, will R134 work with the MoPar V2 compressor ?

I'd like to install A/C in my '67 Dart convertible. Should I consider using a larger condensor with the V2 / R134 ?

Yes, BUT you must make sure the compressor has a Neoprene shaft seal, or it will leak. Neoprene shaft seals are available for this compressor from NAPA.

If you are retrofitting A/C to your Dart, and are determined to use 134a, you will need to take steps to increase the efficiency of the system to make up for the loss of efficiency due to less-efficient R134A being used instead of more-efficient R12. First, select an RV2 compressor (10.5 cubic inch displacement) rather than a V2 (9.45 cubic inch displacement). Second, use a better condenser. A SuperFlow item from Vintage Air (www.vintageair.com) is an excellent bet and they don't cost a lot of money. Thirdly, consider using GHG-X7 Cooltop refrigerant, an R134a-compatible, nonflammable, fully-legal, available-to-the-do-it-yourselfer refrigerant, <A HREF="http://www.cooltop.com">www.cooltop.com</A> . Also note that all hoses and seals in the system must be R134a compatible, that is, barrier hoses, NOT the old nitrile type, and Neoprene seal rings, NOT the old nitrile type. Of course, you must make sure to use proper R134a-type oil.

Thanks, I'd just as soon stick with R12, but the politics I don't want to deal with.

I found a rebuilt RV2 in the trunk of a '62 Dodge at the Pick-N-pull, with everything needed to do the conversion, underdash unit, hoses - the entire system. But, the condensor looks like it's seen better days, so I might as well upgrade it. Other than the fact that the cast iron compressor weighs a ton, this is what I'll use on my Dart, although I guess I'll need new hoses.

Vintage Air is a local outfit here in San Antonio. I'll check with them. Thanks!

: You can use "seasoned" R12 hoses with R134.

Since your system is apart, do replace o-rings and
gaskets.

I agree about the hoses and "o"-rings, go with 134A, also use a 134a compatable
reciever/drier.
