Nightmare Repair
While we were driving from Trinidad, CA to Susanville, CA in our 2001 Dutch Star DP, we experienced some engine over heating about 2/3 of the way. On several occasions, I was able to pull over let th...

I gotta believe if you are driving a 2001 Dutchstar, you are riding on a Spartan Mountain Master chassis, probably with a Cummins ISC motor and a side mount radiator. Spartans design has the hydraulic cooling radiators mounted first, followed by the "charge air cooler", and finally the actual coolant radiator. Don't know what took Freightliner so long, but the problems with this setup can be many and varied. Most common is clogging of the radiator due to leaves, dust, and dirt accumulating in the "pores". Another possibility is that the coolant vs. water is too concentrated. Too much antifreeze vs. too little water provides less cooling capacity. Another possibility is the cooling fan drive motor not turning fast enough. This is a hydraulic motor, driven by a hydraulic pump. This is the same pump that runs the power steering system. The pumped fluid a shared between the two systems via proportioning valves. Also possible not enough fluid is driving the hydraulic fan motor.
Might help to list what Freightliner did to try to correct the problem.
If I'm wrong, and you have a freightliner chassis (I think Newmar was using both back then), the side mount cooling fan is driven by a magnetic clutch. That clutch is known to fail, which lets the fan sit still instead of spinning when the coolant is hot.
