Coolant Level Sensor ( If Equipped ) Aftermarket add-on.
3406E, C-10, C-12, C-15 Monitoring system,standard programmable features of which
comes on engine. Coolant temperature, Oil pressure, fuel temperature. Intake manifold
air temperature and fuel pressure.
The engine coolant temperature is measured by electronic sensor on water outlet housing.
The signal to temperature sensor is used to modify, engine fueling and engine timing. This
information is used to improve engine cold start and white smoke cleanup. This is a 5 volt
sensor is used with ECM indicating Cold Mode Operation.
Coolant Level Sensor. The coolant level sensor is purchased by OEM and installed by OEM.

Point want to bring out Coolant level sensor on above engines serves no value other than top
Tank is low on fluid and is not programed other wise. With Members that own Cummins engines there
Only engine coolant protection is the coolant level sensor, and it is programed to Derate engine
rpm to 1100 rpm. Cat coolant level sensor had 2 wire sensor and a 4 wire sensor. This is a
simple problems that can bring problems for lack of understanding.Dave Atherton Retired Cat
