Meters and Gauges

Instrument Cluster Assembly:

Engine coolant temperature gauge
Engine coolant temperature gauge in instrument cluster indicates temperature of engine coolant with ignition switch in "ON" position. A sending unit in engine changes resistance with temperature.

Fuel gauge
Electrical fuel gauge system consists of an electrical panel gauge and a fuel tank sender device. Fuel gauge indicates quantity of fuel in fuel tank only when ignition is turned to "ON" position. When ignition switch is turned to "ACC" or "LOCK" positions, pointer does not point to correct fuel level.

Speedometer/Odometer/Trip meter
This instrument cluster assembly includes a speedometer, an odometer and a trip meter. Speedometer indicates speed. Odometer records total road mileage. Trip meter records trip mileage. Indicator needle is electrically driven by a precision DC motor circuit. Speed information source is a speed sensor on transmission. Odometer and trip meters consist of numbered wheels that are electrically driven by a DC stepper motor.

Tachometer
Tachometer indicates engine speed in rpm (revolutions per minute) with engine running. A wire to "TACH" connector on ignition module measures ignition pulses of module. An electronic circuit on tachometer converts these pulses to rpm data.

CAUTION: When removing or installing any electrical units, disconnect negative battery cable to prevent possible short circuits which could lead to personal injury and/or property damage.

When replacing odometer assembly, law requires odometer reading of replacement unit to be set to same mileage as prior odometer. If mileage cannot be set, law requires that replacement odometer be set at zero and a label be installed on driver's door frame to show previous odometer reading and date of replacement.
