Re: Boosting AC coldness and air flow

Assuming your fan clutch is in good operating condition, is it a standard unit, or heavy duty? Best fan seems to be a factory style 7-blade. These come on factory A/C trucks, and a HD fan clutch is recommended with them. If all that is up to par, it wouldn't hurt to add a pusher fan or two, but you will likely need to upgrade your alternator & wiring to handle the extra electrical load. I would not switch to electric fan(s) and eliminate your factory system, though some have done it with good results.

If you're not sure what type fan clutch you have, look at the faceplate. Standard has a smooth steel faceplate with fins around the outer edge, and heavy duty has a finned aluminum faceplate.
