Hello all!
I've recently replaced my water pump, and I was wondering what is normal operating temperature range on 4.0L Jeeps? I have celsius temp gauge, and most of the time it's one line below half ( it's around 85 degrees celsius~=185F. I have 195F tstat in Jeep. When I'm on 7-10% incline, temp would rise near half mark- 100C (210F).
Jeep has 32rh automatic with 33 inch tires. Before I installed those tires temp would always stay near that 185 mark - one line below half mark. Water pump, tstat, radiator - all new. Air burped out of cooling system.
Only thing that comes to my mind is
