i got a couple of flex fans today and i was lookin in summit and theirs said they dont fit serpentine b/c the water pump turn in the opposite direction........does anyone run one?......i figured i could just flip it over, but i dunno

 

not sure what your talking about, can you post a pic or link up?

 

Summit offers a LOT of fans and, you can get one in reverse rotation. I think those are mainly for Fords. You should call them to find out what fits.
I've heard, not confirmed though, that flex fans are not going to move any more air, if not less, than our hard fan with the clutch. And that a properly working fan clutch will create no more drag than a flex fan.
Oh, and flex fans flatten out at higher RPMs. Probably not a big problem for our low revving trucks but, something to think about and how you drive.

 

Oh, you're talking about those light weight "Erector Set" looking fans. Don't bother. That viscious fan you're running is about as low drag as you can ask for in a hard fan as far as reducing parasitic drag. That's odd shape with 2 fin and 3 fin clusters on our fans is Mopar's design and they own the patent. Which is why they came out with the flex fans for other models.

The only way to get rid of drag on the engine is with pulleys, E-fans, and perhaps an electric water pump.

 

well, i was thinking it would help with looks too.....its blue with aluminum fins

 

wow. that's a cool word !!! i don't think i can ever top that. hmm maybe, let me think about it.

 

never knew squirrels were that smart

 

i think he's an english teacher. if not he should be.

 

Pffft ... redundant ... all drag is parasitic.

 

not the drag you wear, Bill
