Engine Coolant Temperature Gauge

United States
This gauge shows the engine coolant temperature.
It also provides an indicator of how hard the vehicle is
working. During a majority of the operation, the gauge
reads 100°C (210°F) or less. If the vehicle is pulling a
load or going up hills, it is normal for the temperature to
fluctuate and approach the 122°C (250°F) mark. If the
gauge reaches the 125°C (260°F) mark, it indicates that
the cooling system is working beyond its capacity.
