What is the ideal operating temp for a OM617?
The mechanical cooling fan decided that it didn't want to be on the truck.
I'm not sure how it broke off but it was just laying on the cross member of the truck the other day, all 4 bolts sheered off.
So I decided to install an electrical fan.
The flex lite fan I installed pulls 3100 CFM.
I drove into work this morning and low RPM's the temp was a straight 180*F maybe even a little lower.
At high RPM's the engine would go to +- 195*F.
I think that is a bit to hot but any thoughts....

Thanks.
