Cool Duramax overheating solutions???

We bought a 2009 GMC Sierra 2500HD to pull our 15,000 pound 5th wheel. It seems to have plenty of power, but it overheats quickly when heading uphill. Suggestions for modifications to keep the engine cool??

We've experienced this ... was caused by fan clutch failure to engage the fan. When it engages the roar can be heard in the cabin. Hope this helps. We've had this happen twice in 160k+ miles.

Getting rid of heat buildup is always of interest. The fan may be part of the problem.
I found this to be a very instructive read; http://www.maxxtorque.com/2008/07/du...n-and.html?m=1

Interesting article. But the lly is 2 generations older than your lmm (which is basically an lbz with emissions). If it were my truck, I'd be looking at the cooling stack to see if it's all plugged up between the intercooler and rad. It's a pretty common thing if you google duramax cooling stack cleaning. You'll find all kinds of articles and how to threads on the duramax forums. If that checks out then I'd be looking at the fan clutch.

SK, I have a new 2018 duramax with the external hood scoop. I had only associated it with better performance. The article highlights the importance of good cool breathing too. Yes, the radiators are the prime suspects.

Have the clutch fan engagement checked and radiator cleaned.
