R4 Compressor With 134A

69-er on Tue March 25, 2008 5:10 PM User is offlineView users profile

Year: 1983
Make: Chevrolet
Model: Camaro
Engine Size: 305
Refrigerant Type: 134A
Country of Origin: United States

I am equipping my factory original, non-AC 83 Camaro with OEM AC components. Everything OEM has been installed on the firewall and back. All I need now is the compressor, condenser, hoses, etc. The car currently still has an old compressor from a aftermarket install I did about 20 years ago. I think it's a Seltec.

After discovering the downsides of AC systems consisting of the R4 compressor with 134A, I need to decide if I want to go completely OEM, which was my original plan, or go with a Seltec compressor. If I go with an R4, is there a way to ensure I am getting the best quality built unit?

Maybe I should try to go back to R12?

I haven't found a source of condensers yet either. It looks like the best way to go for efficiency is an aftermarket parallel tube design. Does anybody know a vendor that supplies them?

Also, are there such things as high efficiency evaporators?

Thanks!

What size are you looking for? We have some universal PF condensers. Right now you may find it difficult to find a PF condenser. One of the main vendors has back ordered all condensers until after September. This is the reason we no longer have the link on our main site. I have some other options on the way. But will wait until I have them on hand before I re-activate the link.

You will be better off buying new R4, not a reman unit. Tim sells the new units. I installed one in a K1500 I retrofit a few years ago, works beautifully.

The main factor in good cooling will be the condenser. Since you are starting with a new system, you can go with a parallel flow model. No need to go with R12 if you have a good condenser.

I have basically the same a/c system in my '80 Malibu (Camaro is covered in the same factory service manual). The OE evap does work fine with R134. I'm sure it can be upgraded, but have never had a problem with it. The big issue is the old style condenser, not the best with 134.
