would like too take fan off and clutch and replace with electric fans. but dont wont to spend the 500-800$ for flex alite fans found a couple at oreilys for 100-200$ does anybody know if this will work?

I installed the electric fans from Flex-a-lite on my 2nd gen and didn't see any improvement in mpg performance. The engine seemed a little more responsive on acceleration without the big vicous fan turning but you will loose some towing capacity as the electric fan is limited to 20k pounds GVW.In the end this project wasn't money well spent because my main purpose was to get the mpg gain that Flex-a-lite advertises..

I agree, you loose cooling capacity and don't gain anything.

I don't believe Flex-a-lite electric fans are recommended for HD use. I used a Flex-a-lite flex blade with no clutch on my 1/2 ton for towing... it brought the temps under control. It's been a while but think it went to a 6 blade. I didn't notice any MPG difference. With my C30, 454 gas & etc, the only thing that mattered was the AC.
