Red stop engine light?

Fluid levels. engine oil, coolant, alternator/water pump/AC belts.

 

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

 

Any other lights, CEL , DEF or emissions Derate.?

Is there any low coolant warning, even though its full...... level sensor or float?

 

...just make sure gas pedal is all the way to the floor !

 

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

 

Thats kinda given. Hes asking for common places to look without hooking up. Which in most cases is like sharpening a knife in the dark. A waste of time and painful.

 

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.
