Im guessing you have the Flex-a-lite electric fan set up. Are you towing a heavy load? If so "Electric fans are not recommended for primary diesel engine cooling when the combined gross vehicle weight (CGVW) exceeds 18,000 pounds (truck, trailer and load)" according to the Flex-a-lite website.

The flex-fan is not a electric one has good air flow as i can sit in stop start trafic on the bloody hot day and not a thing happens but go up a long step grade and gets hot , could the auto be doing this ???

I think that with a load on a grade your flex fan isn't moving enough air . Keep in mind pulling a grade with a load you are really making a ton of heat , engine , turbo , tranny ........ you really need to have everything working well to keep the temps down . I had a truck a few years back that was doing the same thing . I pulled the radiator , a/c condenser , and radiator out and pressure washed them all . You shoulda seen the dirt and debris come out . Anyway that fixed it . I had a stock clutch fan . I think it's a matter of just not getting enough air moved across the motor .
hey that's a good point.. that seems like a pretty dusty environment, so I'd imagine it very possible for a pretty good layer of just crud to build up on everything..
I try to backwash mine every time I think about it, and I've never had heat issues, even hauling the horses up the hill from US 23 around 270 to the Ohio State Fairgrounds.. it's not a big hill, but it's a loooooooong sumbitch.

My wife showed horses for years when she was young . She took 8th in State of Ohio in Equitation . My twin daughters just turned 9 . It will be their first year showing (not lead line) . Hopefully they will follow in mama's footsteps .
Sorry for the hijack .

When you're pulling the grades how fast are you going? 35mph or 55Kph or greater?
if so then you have more air flowing from the speed of the truck and the fan is not making a difference.
If you are going slower than roughly those speeds then the fan is needed and a flex fan deforms and does not pull as much air when spinning much faster than idle.

They are made for drag racing and not trailer pulling. Your clutch fan is much better for what you are doing. Moves a lot more air over the entire rpm range.

we go down for Equine Affaire sometimes.. when we do, we exhibit the Clydes.. so we make that trip with a 3,500 lb trailer, 3,600 lbs of horse, 20 bales of hay @ 70lbs per bale, four saddles for another 350 lbs, tack and show clothes, plus chore clothes & underwear, towels, cleaning supplies, buckets.. yeah, we're easily hauling 9,300 lbs...
