Just installed my newly rebuilt engine in my 2000 D2. Got about 250 miles on it now of trouble free operation with no codes. However, the coolant temps are irregular. I installed all new hoses and a new low temp thermostat from lucky 8 when I installed the motor. With my scan gauge II digital readout, the truck warms up to 188-193 degrees and will stay in that range while driving. Once I stop, or idle at slow speeds the temp rises, almost to 210 before I realized it today. The temp gauge reads in the normal range almost dead center. Is this normal? I think I might have a bad viscous clutch, but not sure.
Also, I have followed disco mikes procedure to bleed the system multiple times, hoping it was trapped air. Each time I never released air, only coolant as it should be.:dunno:
