Engine overheating

We have a 1999 2500 4wd Dodge diesel with 65,000 miles. This month pulling a 5th wheel, (8000 lbs) total, and at an altitude of 9000 feet, it overheated; twice we had to stop to let the engine cool, the overfill bottle was full and spilling. I am perplexed, not one of the people I know has ever had the experience of an diesel overheating; does anyone have any ideas? The truck never overheats under normal driving conditions. Please help.

Re:Engine overheating

Change your thermostat and all should be well. My dads went south on him and it only overheated in OD while pulling his gooseneck. thermo was half colapsed. I beleive it is designed that it will not stick or fail in the closed posistion.

Also, check your fan clutch.

Re:Engine overheating

What BBD said, there was a batch of bad thermostats, I had one on my '99, I cannot make it heat now at all. Used to overheat on any good hill in the summer.
