05+ trucks come with the efans and everything not just the SS. FAL suck. period. LS1 fans are even better and at least half as much. 34" radiator will be needed for the 05's which wil also add more cooling power

 

I have heard that the 05's come with them before but I know of a lot of 06's in my area that don't have them. I am talking of the 1500 HD crew cabs and 2500HD's both with 6.0L. The 1500's must come with them then?
Why do you say the Flex's suck? Mine never failed, just don't move enough air. Would the e-fans be beter in that aspect?

 

BTW, sorry for the hijack MrMischief.

 

I run the FAL 292 - never had a problem with them - albeit I don't use their controller, I have my own wiring. See my cardomain for pics and narrative.

In 100* heat my coolant stays right at 190* (where it belongs) and the tranny sits at 165*. Even in bumper to bumper traffic, the tranny will creep up to 180*, the stays stays right at 190*

They bolt right in and give full coverage of the radiator.

 

its cool, im getting all kinds of info like i requested. i am curious tho, what size radiator comes in the non-efan i guess 99-04 pickups? i asked the other techs at our shop and even they didnt know that there were 2 different sizes.

 

My truck has the 34" stock size rad, I just went to a core that is twice as thick. My flex's do not cover the complete rad, how do yours. Same 292's I believe. Misses the top two corners and about 3" on the botom. The stock fan shroud covers every square inch and I need it all.

I think you can not say which years came with which rad size. Depends on engine and chassis. May be wrong, been wrong before...

 

34" radiator, the FAL 282's cover that sized core completely. Thats what i have, and according the ever so accurate hand gauge, it seems to flow about the same as the 05 fans on my dad's 05 Denali...

 

The 5.3s got a 27" radiator. The 6.0s got a 34" radiator.

Correct with the 282 for the 34"

 

so i guess its safe to say that my 02 4.8 has a 27" radiator?

 

Yep
