I've got a 1983 Class A RV with a BBC 454. It's the original engine with at least 75k miles on it and the A/C unit no longer pumps cold air. I'd like to remove the A/C unit all together because I'm not using it and it's just one more component the engine has to turn.
So what's the proper way to remove the A/C system? I'm not so much interested in knowing how to unbolt the unit from it's mount on the engine, but rather which hoses to disconnect/cap and is there anything special I should do or know to accomplish this task?
I've also read somewhere that removing the mechanical fan off the front of the engine and replacing with an electric fan will also lessen the load on the engine. Do you think this is a good idea?
I appreciate any feedback you engine guru's can provide.
