Engine Coolant Level Sensor

G11718907

The engine coolant level sensor is located in the coolant expansion tank, which is located in the right side of the engine compartment.

The engine coolant level sensor reacts to the influence of a magnetic field. A float with integral magnet is located inside the tank, over the sensor tube. The sensor has contacts inside the tube, which are normally open. When the fluid level reduces, the magnetic float moves down the tube. When the magnet reaches the sensor contacts, the magnetic field closes the contacts. The sensor connects hardwired to the Central Junction Box (CJB) which receives the signals from the sensor.
