Section 13-09: Gauges, Warning Devices, Miscellaneous—Electronic | 1993 Mustang Workshop Manual |
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.
