I finally get to work on my truck and do some upgrades here and there. The first one is headers and e-fans. While I'm in there doing some work I thought I might up grade other things too. Is there a good upgrade for a radiator?

My truck is a RCSB '04 gmc sierra completely stock right now.

 

The only reason to upgrade the radiator is if the e-fans you get require it. For example, the 05+ truck efans only fit on a 34" core radiator while yours is a 28" core.

 

Glad I asked, I guess I'll have to upgrade the radiator then. I have the 05+ efans. I got a great deal on them (20 bucks) so I'll need to get a new radiator.

 

Yea thats a steal for those fans..

 

if you need help with a harness lemme know..

ebay has new 34 inch core radiators for $100 shipped
WORKS great!

 

Yeah I read that efan harness 101 and it might aswell be in Swahili. I'm more of a "hit it with a hammer and see if it works" type person. I'm the Jeremy Clarkson of the truck world.

 

I never under stood why people upgrade these. The stocker works fine. That is a deal on the fans though

 

Ah come on... its laid out there for you one wire at a time..
Everybody overthinks the small stuff.

 

My truck had a hard time last summer in the Texas heat here in DFW so I figured I'd try upgrading stuff.

I'll give the wiring a try but if i burn it down I'll post some picks.
