I ran across the new flex-a-lit electric fan for the 03-08 cummins, i was happy.. I use to run one on my 1500HD and loved it..

So i called flex-a-lite to order one and they asked me what yr mine was and i told them it was on 05 cummins and they told me, it wont work on your truck and i asked WHY?? They told me there only for the 03-08 cummins without electric clutch... SO correct me if i am wrong but doesn't EVERY 03-08 run an electric clutch???

SO if EVERY 03-08 has an electric clutch they why advertise "YOUR ABOUT 4 HOURS AWAY FROM BETTER PERFORMANCE"

The customer service guy i talked to did tell me this.... I dont write the advertisements i just answer questions.. That was after i told him correct me if i'm wrong but dont all 03-08's have electric clutchs..

 

Well that bits it I was looking forward to this. I seen it in the new Deisel truck mag and was thinking of ordeing it but guess not now. Got to do anything to save mpgs here @ 3.69 a gal I can't afford to go camping this year.

 

I never had luck with flex-a-lite, tried to get a "kit" for my Jeep, got the run around on a manual control switch, ended up rigging Radio Shack stuff to make it work

Diesel is $3.93/gallon in my neck of the woods

 

Its $3.89 here and rising..

I was always told diesel was cheaper to make then gas, is there any truth to that??

 

Swapping to that fan would be a major step backwards in cooling capacity!

i agree as well.they won't pull or suck as much air as the stock fan.

 

That's what I was thinking, maybe it can handle a stock truck, but what about a modded truck pushing 400+? I'll stick to the setup I have now.

 

What temps are considered hot on our trucks?

 

Scotty, when your 6" tip gets cherry red - it's time to back off on the Smarty.

 

i guess i better get lazarsmith to make me a ss hood stack so i can monitor my temps via windshield

 

Why didn't I think of that?

My hole saw or yours!

 

What is the CFM of a stock fan? Does the stock fan run all the time or free wheeling? What would be the hp advantage be?

 

always spinning, I believe. I don't know exact numbers, but I imagine its noticeable.


I wonder if turning it off would help it warm up faster in the winter?

 

The OEM fan pushes a LOT of air, but only when the electrically-operated viscous clutch engages... most of us never get to hear it turn on - it's unmistakeable, like there's suddenly a propeller under your hood.

 

i tought they all had the elec. clutch. i have them on my 02 and planned to get a kit for my 07 because i have been very happy with them. i hope that the price is the same as the 2nd gen i got them for 490 from a local guy.
