On my DD16 Detroit. The alternator belt also drives the water pump. So the engine would get an over temperature alarm.

Coffey and Mattflat362 Thank this.

Five replies so far and no one has mentioned checking what code(s) it threw.

Water in the oil = stop.
Could be just a sensor gone south too.
Think I'd rig a jumper to bypass the sensor in the coolant surge tank first.
I drove mine until I think it had all the emissions codes when the SCR died, and still never got the red light.
Sniff around your coolant sensors. Eliminate those first.Mattflat362 and earnies2 Thank this.
