R-12 AC question

[sixt9rsx33]

Regarding a nice survivor car that has an R12 AC system that is not working properly. Do you bite the bullet and convert to a R134 system? Or suffer in the heat, don't drive the car much in the Summer. Concerned about removing the originality.

Fix the AC n drive it!

Yes, I agree. R12 is superior and is still somewhat available

I am a fan of originality, especially of survivors of course.

Cheers,
Anthony

Anthony,Didn’t you list some R12 for sale recently?

Use Duracool. No conversion or flushing necessary. I used it for years.

R12 is readily available on Facebook marketplace by the can or cylinder. Most guys are asking $40-$50 per 12-14oz cans, so its not cheap. You will need about 60oz for the average '60s based system. If your system has not run for some time I would recommend flushing the system and pulling a vacuum to be sure it is not leaking. Replacing the dryer is also a good idea. All in all, just standard maintenance to the system. Converting your system to run 134a is much more involved and costly. Nothing cools like good old R12 in an original system.

Good idea to replace the front seal in the A6 compressor also, notorious leak.

One of mine, replaced the seal and dryer, evac/recharge with R12 3 years ago, blows ice cold.

Where did you get the front seal from?

Can't beat R12 for freezing yourself out of the car

Thanks for the call out Richard, yes, I have some NOS R12 cans available and listed in the parts for sale section - couple of cases on hand at the moment.

Cheers everyone!
