I've not heard of or seen any diesels running electric fans on trucks
(big or small)... I don't know why? I would assume that some of the
diesel cars like the Jetta and others have electric fans, but as far
as I know none of the pick-ups or larger trucks run electric fans.
I know both flex-a-lite and perma-cool make a dual fan setup for
I wonder if you could do something similar with two spal 16' electric
fans and a wiring harness from painless... cheaper and get similar
I like the setup from perma-cool but I've never seen anyone
who has it, plus its fairly expensive........ and I'm unsure if it
performs any better than a stock fan-clutch setup? I know the
electric fans should pull more air at idle and very low engine rpm but
I wonder overall if they do a better job.
Both vendors quote some performance values in CFM (cubic feet per
minute) but I wonder if those numbers approach what a stock setup with
a fan-clutch will do. I have a 92 K1500 with a 350 and aftermarket
radiator along with a good radiator (stock) shroud, with a HD GM fan
clutch and an aftermarket flex-a-lite fan-clutch fan which seems to
work good for me. It really pulls some air through the radiator, of
course I have no way of knowing what kind of CFM numbers would apply.
I don't want to spend $500.00 plus to find out the stock cooling setup
out performs the aftermarket electric.
controls which caused melted fuse holders and drained batteries.
I don't know of anyone running a F-a-L, but I do know a couple people that
have Ford Taurus 2 speed electric fans in their pickups. They're 14 or 16"
(can't remember) and are 1400cfm. Thats a cheaper way to go for electrics,
go to your local pick-a-part to find one cheap.
