Air Conditioning belt

[Bob Moss]

I have a 1974 C3 454 vette. I bought it used. So I didn't see the engine set up from the factory. Apparently the previous owner had removed the AIR pump from this engine. Every parts store that I have visited has told me that this engine should have an AIR pump. My question is what size air conditioning belt do I need for this engine without an AIR pump? I know there is one because the car had a functioning belt when I bought it.

Re: Air Conditioning belt

i've got a 74 454 4 speed C-60 and they definitly came with AIR (smog ) pumps. Any NAPA store worth its salt should be able to measure and match a belt from their stock for your car, whether or not you use a smog pump. good luck, mike

If you have an automatic transmission your 74 may have never had an air pump. Check your emissions label and se if it reads AIR.

Thanks for getting back to me. You bring up an interesting thought.I bought this car out a divorce settlement in 1976. The folks involved couldn't reach a settlement. So their lawyers got together and sold all of their assets; including a home under construction that had a roof but no walls. Just bare 2 X 4's The guy that had it was a CPA. I doubt if he would have removed the AIR pump himself. I'll check the emissions label tonight.

If you're interested in original style belts for your '74 (not sure about the correct markings and GM numbers), I had the best luck for locating the right AC, Alt., and Water Pump to Crank belts at Doc Rebuild.
