Electric fans
 

What are the pros and cons with putting electric fans on my truck?

Pros: EVERYTHING
Cons: Initial cost and time to put it in.

Looking to put some in myself. Check out BBD, they have a product that claims (and probably is) better than Flex-a-Lite, and is much less money.

I've heard that there not good for towing or for trucks that idle alot. any truth behind that?

Depends on the CFM they put out. If your looking to gain mileage, not really gonna help when towing anyway.

I have heard that before. But what can pull more? 2 - 16" fans or one 22-24"? A 24V cummins uses about 15% of its cooling abilities when unloaded. Practically nothing. 6000CFM will do just fine.

So there better for trucks that idle alot?

IMO, they are better for everything.

Derale Performance Dual Electric Fans

i've been looking for a cheaper alternative to the flexalite.

Brice will take care of you,as he does everyone else. You may need a few of the fan controllers as well, if you want it to come on with A/C as well as temperature. Still, less than Flex

I had mine flex-a-lites on my truck for 2 years and are great.MPG have increase,spool time for the turbo:scare2:what spool time.If you idle alot you can set up a switch that you can have the fans on all the time of you can have it set up to have it shut off.Just did a trip 2 weeks ago to blowing rock,NC for dyno day and hand cal 22 MPG on the highway.
