My 66 Chrysler 300 has a none working AC system. And my goal is to fix it during this winter. Is it possible to make it work with the new type of freon? Where can I get a rebuild kit for the system. Thanks

You might see if you can retrieve some past threads regarding this. From what I've gathered R12 is no longer being manufactured tho there are tons left. As you know it (the single cans) is available on eBay/CL tho it is pricey. To changeover I think you need the new type "barrier" hoses, the reciever/drier needs to be changed to the new type, the valve at the firewall needs to be changed, the oil in the compressor needs to be changed to the new type, new type of O rings in the hoses/fittings then vac pump the system empty which is std procedure then add the new stuff & I think you go by weight & use less of the new type of freon. Some say it dont cool as well as R12 & others are happy with it. dont remember if a larger evaporator (next to rad) is needed (or recommended). I'd wanna check the system for leaks in the process so I dont have to mess with it again. Might be more to it than this but here's a BTT for ya. EDIT A '66 "300" would have a monstrous condensor so you're good there

I have converted quite a few cars to 134 and all I have done is changed the fittings and evacuate then charge with 134. All the hype about changing O-rings and special hoses and receiver/drier replacement is not necessary. Some of the newer kits come with improved oil in the can so it is added during the recharge.

I converted my 87 Diplomat over, with the C171 compressor. I was not real impressed with it's ability to handle the Texas heat.

Well, a charge of R12 for your car will run >$ 500 if it leaks, you get to do it again. I too have changed many system's over. Fix the leaks, new orings, Fittings,new receiver/dryer and evac and fill. Need to replace the receiver to avoid contaminants that will coorode your compressor. Astrobuf

The R-134 molecule is considerably smaller than the R-12 molecule which simply means it will leak out faster and most R-12 systems are defunct because the refrigerant leaked out. In the long run the cheaper R-134 might wind up costing as much as the R-12 for the same length of service.

Yeah I definitely dont know my way around AC systems. I'd (likely) have my maintenence man buddy do it with his R12 gauge set

We pressure tested the system to day and it's leaking from the input shaft on the compressor. So I need to rebuild the compressor, but who has parts for it? Thanks

No need to rebuild the compressor, just install a new seal. Seal kits are readily available.

No it isn't, I have a 509 license and they're easy to get online. BTW, it's also illegal to go 66 mph in a 65 zone....how many here are guilty?
OP means an EPA section 609 license and yes, very easy to get online.

Here in Md I had to take a course in 1992 to get my certfied license for R12. Course anyone can buy the 134. I have been around and working on AC systems since about 1974. To me the 134 gets almost as cold as the R12 but I agree it takes longer to get that cold. I have done many conversions like Gus has done converting an R12 system to 134 because most people dont want to pay what the R12 is and they dont want to shop Ebay for it. I did not know you could get the R12 much cheaper on Ebay as thats nice. And to think of how many cans of R12 I used to have around my garage since most of the time under warranty we could get an extra can of R12 when we worked on it and I must have had 2 cases of R12 at one time but not anymore.
