I have a one -half ton Chevy truck with a 235 c.i. six engine.This is a 62 year truck The truck also has an add on air conditioner which requires a little help in the cooling compartment. I have the original four blade fan. Did Chevy make a blade with five or six blades? The truck does not overheat but a mechanic suggested an upgrade on the blade to help cool the AC condenser as well as the truck. Any suggestions from anyone with this problem? Thanks in advance for any ideas!
