R12 recharge or R134

Year: 1965
Make: Chevy
Model: Corvette
Engine Size: 327
Refrigerant Type: R12
Country of Origin: United States

This Question is for "Mitch"

Hello I was on the C2 Corvette Forum and this Forum was recommended for advice
I have a 1965 Factory A/c Convertible Corvette and 2 day ago I replaced the Factory A/C compressor with a rebuilt A-6 It stopped working about 15 minutes after install. I replaced the complete A/C system including POV valve New oil in new compressor ne dryer
had the system flushed out and replaced with new R12 freon. Now the parts store is warranting the compressor but will not refund my cost on the R-12 Should I flush out the system and use R12(freeze) or go with R134 It can get expensive if the Compressor goes out again
Please advise

Thank you
happy holidays
Bill

We have no R134a issues with the company we use for A6 remanufactured compressors. Vettes tend to have poor air flow across the condenser. So I try and stay with R12 for that reason.

I would keep it R12 if at all possible. If you decide to go with R134a, you must flush the mineral oil out and use either a "double end capped" Pag 150, or BVA Auto 100 ester oil using the wrong oil can kill the A6, but not much else...

Mitch is in heaven, was taken there before he could experiment with POA valves and R-134a. Could try praying to him, let me know if he answers.

R-12 is staying in my Supra, even if I have to steal some from Gore.

Is this vehicle being charged with R12 or is Freeze 12 being used? The statement leaves a doubt in my mind? Also, what happened the the A6..those things are almost bullet proof.....please elaborate.

A personal opinion...stay with R12!!! Your system is designed to work with this and will perform much better with this refrigerant. Think in the long run, you will be more pleased with the outcome.

Good luck with your repair.....

I'm wondering how a Corvette can have poor airflow across the condenser but still have adequate airflow across the radiator which is behind the condenser?

Simple, the condenser & radiator are laid back at an angle. Yet the design of these components have the standard tube & fin design. So you have some air flow flowing across the cond/radiator compared to if this unit was sitting straight up and down. While the angle of the fin and cooling tubes can catch some air. It can also cause some turbulence. Also the openings on the vette are designed for a minimal amount of air flow. So adding an additional heat load you will with R134a. It's just not the best vehicle to convert in my opinion.
