Coolant Level Sensor: Description and Operation

DESCRIPTION
A coolant level sensor is mounted on the recovery reservoir and is used to illuminate the CHECK COOLANT indicator located in the cluster. When the ignition is turned to RUN position, the indicator will prove out momentarily and turn off after the engine is started, indicating adequate coolant fill. The CHECK COOLANT indicator will turn on when the coolant level drops below the FULL COLD mark located on the side of the recovery reservoir. When indicating a low coolant condition, the indicator will illuminate and remain on until the coolant is filled to the FULL HOT mark and vehicle ignition is turned off and then cycled back on.
