I keep hearing about guys overheating with efans...I want the extra horsepower, but I don't want to sacrifice the cooling ability....input would be greatly appreciated...:bowtie:

Shit mine are set low, Im running at 150*

Gotta have the proper sized cooling fans. Figure a truck will need at least 4000cfm of air to cool. :imo

The overheating issues you are hearing about are most likely related to improper setup i.e. - they're set to kick on at the wrong temp or wired incorrectly.

i know the windstar fans on my truck cool better than any clutch fan GM as ever put out...

 

[kdubbz]

Or have a manual switch to control the fans inside the cab, therefor you tell the fans when to cool the coolant down, just keep watching the engine temp on hot days though.

How much cfm does the clutch fan pull/push?

well I'm sold on e-fans. I like the look of Flex-a-lites, and I'm not far Nelson's, so I'll definitely throw a set of those in and have the PCM tuned to control them. That's the best way to do it, no? This is for a 6.0.

Nono, stock fan pulls around 10k :shake:

Go with OEM fans.

I don't think GM ever paired LQ4s w/ efans...:hmm:

You can use 05 OEM e-fans with a 34" radiator.

What size radiator does a 1500HD have stock? I would go measure it, but I don't have the truck yet. I ordered freight yesterday, so it should be in this weekend.

I always thought about doing the E fan is it really worth it as far as getting better gas mileage and approx how much power do you get out of one?

Doesn't even have to be GM fans...ford makes some REAL fine e-fans :read:

can get anywhere from 10-15 horse out of them, obviously only about 5 or so to the wheels. Mostly it cleans up the engine and makes it easier to control your engines temps :imo because you can tune it to run lower than a stock clutch fan

ugh...hooking f*rd fans up would probably be a pain in the bazooka. :insane:
