I see acouple of posts on different forums re electric fans on Duramax. Has anybody actually had them on a Duramax to give first hand experience? I tried some twin electric fans on a 93 stepside with a 502 injected motor and they were a disaster. The amount of shrouding they had wouldn't allow enough airflow. Has anything changed?

McRat runs them on casper last i recall. I dont think they are enough for a everyday work/tow truck though? Other than that i dont knoe anyone who runs them, most folks stay away from them due to the lly's known overheating issues!!

Bullbar

It was originally what we call a Bullbar over here for hitting Kangaroos and Cattle on the road. It came with bars up around the headlights etc but I think spoils the look and the top bars were just above the headlights and at night the light reflected back so I trimmed them down. Dont think I have a pic of it before I cut it. I'll try and upload a couple if I can - It will be a little dirty though. Cant upload pictures. I'll pm them

Flex a lite offers an electric fan option and it looks pretty good. It will remove a huge drain from teh motor, and help pull air when ever you need it to. Nic Damico (DP challenge winner) runs them. I want to say it pulls 6200 cfm, but I hae to pull out my price list to check.

The first models have bad electric controllers that will melt your wiring.

They recently fixed it, and we got the improved wiring and it's working well.

It is not recommended for heavy towing, and I'm not sure there is claimed good HP gain.

Trying to revive an old thread, wondering if there are any more opinions on this now that its over 2 years later.

Considering going with a dual monster flex a lite. I like the idea of an electric fan so that my current one doesn't drain my engine of that juicy HP.

electric fans

I learned the hard way that electric fans do not pull enough air thru the radiator at high speeds and causes overheating. It's your motor but I would never put electric fans on mine

Well, I guess that's all I needed. I was hoping there was at least one person on here with personal experience. I guess I'll have to explore other options.

Do you have any experience with just a fan replacement? Or should I just leave well enough alone?

i put a flexalite on one of my 03' fleet duramaxs and worked like a champ until trying to tow a 20' trailer loaded with 4wheelers through nebraska in the middle of june and it overheated. so i took the fans off and then later it was still runnin hot so i flushed the cooling system and that tixed that i didnt put the fans back on yet but they seemed to worked really good. plus they sound cool when they are still runnin after you shut your truck off.
