Temperature Gauge: Description and Operation
Description
DESCRIPTION
An engine coolant temperature gauge is standard equipment on all instrument clusters. This gauge is located on the right side of the instrument cluster,
just right and below the tachometer. The gauge consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 90
degree gauge scale on the cluster overlay that reads left-to-right from C (or Cold) to H (or Hot). An International Control and Display Symbol icon for
Engine Coolant Temperature is located on the cluster overlay, directly above the hub of the gauge needle.
The engine coolant temperature gauge graphics are white and gray against a black field except for a single red graduation at the high end of the gauge
scale, making them clearly visible within the instrument cluster in daylight. When illuminated from behind by the panel lamps dimmer controlled cluster
illumination lighting with the exterior lamps turned ON, the white and gray text and graphics still appear white or gray and the red graphics still appear
red. The red gauge needle has internal optical illumination. Gauge illumination is provided by Light Emitting Diode (LED) units soldered onto the
instrument cluster electronic circuit board.
The engine coolant temperature gauge is serviced as a unit with the instrument cluster.
