English
This gauge shows the engine
coolant temperature.
It also provides an indicator of how
hard your vehicle is working. During
a majority of the operation, the
gauge will read 100°C (210°F) or
less. If you are 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.
