I'm gonna convert my belts to a serpentine system from late 80's early 90's camaro V8. I'm sure that the alternator will be plenty powerful. But how about the A/C compressor, are they up to the task of cooling an elky if converted to 134? What is the compressor nomenclature R6, B18, C32 Bingo!?? :-D

I'm not any type of expert on A/C but I've read that matching the condenser and evaporator is actually the trick to getting an A/C system to work well. I think the compressor for the El Camino and the Monty or Chevelles are the same and the same as the ones for the Camaro. A Camaro has more interior room than an ELky so if the Evaporator and condenser are from the same vehicle, according to the article I saw, then it should cool fine.

I have converted several of my cars to R134, including my 1979 El Camino with no problems. There is a slight drop in the outlet temp but it is not significant. I've done the conversion by flushing out the system very carefully and replacing the receiver/drier etc. and I have also done a quickie by just replacing the ports and freon with a fast flush and didn't notice any difference, although I would recommend complete job for any vehicle you really care for. The GM R4 has a good reputation although it's big and ugly. The little Sandens are efficient and easy to package.

I converted to 134 about 4 years ago. No major changes were made, although I did install new rubber hoses because the originals were in poor condition. Has performed well for all this time.
Thanx for the insight. I just got a complete serpentine system from an 89 F-bird. I'll take a little while to clean it up & powder coat. Then give it a shot. I'm gonna make another post about POA Valve substitute, if anyone with an early POA system has experience please tell me about it.
