Engine Coolant Temperature Gauge

Metric

English
This gauge measures the temperature of the vehicle's engine. If the indicator needle moves to the hot side of the gauge toward the colored line, the engine is too hot. If the vehicle has been operated under normal driving conditions, pull off the road, stop the vehicle, and turn off the engine as soon as possible.
