Cummins ISB 6.7 360 hspwr normal engine temp range

Watching our year old MH temp last night coming home from vacation and I noticed it running at about 201 - 210 mostly at 205 degree. Now it ran going during trip out about 198 - 201 but it was cooler ...

All I am saying is that a Ram truck has no alarm and the engine often ran up to 230 without issue. Tranny once climbed over 250 outside Telluride.

Which factory are you referring? Chassis or Cummins?

Fan sounded like it always did.

I don't think that 200-205 is hot at all. My 8.3 will run about 210-220 with tranny temps staying around 200.


It wasn't the factory, my bad. It was the Cummins information line supplied by Frieghtliner. So it was Cummins.
