Mslipac,

Sounds about right. Engines are supposed to run hot. I read that the Navy did a test and found the optimum running temperature was about 300*F for Diesel engines. Of course this was for large Marine Diesels.

I think the temperature cars run at is related to the boiling point of water. As long as they don't boil over, they are not too hot. Notice where the red area is on your temp gage.
