Another thought. Replace the water pump with the newly designed for more water flow. Here’s an example of the difference. OEM Cummins is the only one making the new version.the old one is the all metal. 

I took your advice and installed the updated water pump. We'll see if that helps. Thanks!

Thanks for the advice. I will eliminate as advised until the problem is resolved.l

Euphoria2me, Welcome to the FMCA Forums!

When you say its overheating, do you mean it boils over or just the temp gauge runs high? 

If just the gauge it could be inaccurate, ours climbs into the red often and when I look at the digital readout it never goes over 190 degrees.

How old is the radiator cap and what PSI is it?

Have you tried to downshift to raise the RPM's and see if that corrects the concern? 

Thank you for the welcome. Temp gauge shows 225+ and alarm goes off. As I indicated, the radiator cap was changed. Higher RPM's helps but does not solve the problem. I'm showing signs of excessive heat on engine door insulation.

My 2005 Monaco Diplomat overheats only going up hill. Had the radiator and CAC removed and cleaned in Denver, changed the filter, radiator cap and checked for exhaust leaks but she still overheats going up-hill, not on flat terrain. She has a 400 ISL Cummins with 62000 miles. I'm running out of options. Any technical suggestions based on actual experience with this problem would be greatly appreciated.

I have a similar problem with my 2005 Monaco Diplomat with a 400 ISL Cummins and 62000 miles. Had the radiator and CAC removed and cleaned in Denver, changed the filter, checked for exhaust leaks and she still overheats going up-hill, not on flat terrain. I'm running out of options. Any suggestions?
