Temperature Gauge: Description and Operation
COOLANT (WATER) TEMPERATURE METER AND SENDER GAUGE
DESCRIPTION OF CIRCUIT
The coolant (water) temp. meter is located in the instrument panel and its sender gauge on the inlet manifold. This circuit is as shown.
The sender gauge shows different resistance values depending on the coolant temperature. This causes a current flowing through the temperature meter
coil to change, controlling the meter pointer. That is, when the coolant temperature rises, the sender gauge resistance is decreased with more current
flowing through the meter coil, thus allowing the meter pointer to move away from the "C" position.
