I want to put elec fans in and get rid of the noisey power robber clutch fan! What do i need and where do start? I'm going to get a tune put on it so i thought i should do this so the program could tune the fans on!

 

I have the Flex a lite 282's and they work really well,It comes with a controller in case you cannot get it tuned

 

Search is where you start my friend, search. This has been posted to death. If you have a specific question, then ask and we'll rehash it again.

EDIT: Here's a how to that I used for mine. http://james.jaguar.net/agreif/fans/fanstech.htm

 

good link!!!!!!!!!!!

 

I did search, did not know about 2004 denali fans! But thanks for going out of your way to tell me to search, wouldn't of ever thought of that!

 

Thank-You!

 

Can i put factory 05 fans on and is there a wire port there on my 04?

 

Factory 05 truck fans will not fit "unless" you have a 34" radiator. This radiator is a direct replacement for the smaller one.

What do you mean about a "wire port"??
There is an empty slot in the pcm connector to control the fans if that is what you mean.
It is pin 42 on the blue harness.

 

when you're using the search, keep the topic of search simple. Instead of searching for "2004 denali fans," search for electric fans, e-fans, e fan, or what they're commonly called as "LS1 fans."

I'm sure that your next question will be for how to hook them up, and reading about a harness. So do a search for "harness."

You can either search by the title in the thread, or the entire thread. Hope this helps.

 

Hey, no problem! Nice to know there's one more smartass on the forums.

Seriously, there's nothing to it, and nothing is different from GMC to Chevy. The only thing that makes a real difference is running large vs small radiator. The LS1 fans are a good choice for either (they cool my LQ9 SS just fine in 100 degree heat with AC blasting). I got my LS1 fans for $60 shipped with a broken tab on them (didn't need it anyway since it was a lower mounting tab that you don't need putting them into a truck), so it can even be cheap to upgrade. I think I spent another 20 bucks putting together the wiring harness including connectors and pins.
