2500cfm is weak for the size, and that one is probably too wide for our radiators. I'm going to try and squeeze dual 12" fans onto a custom shroud, not sure if I'll be able to get them in or not. I think Rangerbob had the measurements in his e-fan thread, and I'm pretty sure our radiator was 23" wide in between the end tanks.

If that one would fit on the radiator it'd probably work great. I'd measure before ordering it though.

When I did the shroud for my SPAL installation, the height (between top and bottom tanks) was 18" and width was approximately 24" between the OEM shroud top hanger hooks.

I wrote about this a while ago, so I'll keep it brief here.

I personally called Flex-a-lite and asked them what they suggest for my truck. They said to refrain from anything under 3200CFM.

The exact fan they suggested was: http://www.performancecenter.com/pr...+Fans&sf4=Universal+Electric+Fans&universal=0

A friend of mine with a Colly here in Ontario, has the exact fan, and he's happier than a pig in shit.

If you are interested, I can get those fans for like $20 off the price you see on PerformanceCenter. And their shipping is only like $11 or somehting, cheap.

Will these fans help or fix the rises in temps that I seem to be having out here??

What I mean by this is; I'm running 20's that are 9" wide. When driving on normal flat ground or slightly hilly everything is fine even with the A/C on. But as soon as I start to climb any type of hill that's slightly higher grade the temp goes up with the A/C on OR not. Now "normal temp" on "my" truck is just a hair under the half way mark. By the time i get to some of the hills out here it could get as high as damn near 3/4's. IMO I think it's getting to high. It used to do this with the stockers, the extreme 18's and now even worse with the 20's. Now I do understand bigger wheels more weight etc. etc. so it will go up a little. It's just that it went up even stock.
