Engine Coolant Temperature Gage

United States
Canada
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During a majority of the operation, the gage
will read 210°F (100°C) or less. If you are pulling a load
or going up hills, it is normal for the temperature to
fluctuate and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (1 25°C) mark, it indicates
that the cooling system is working beyond its capacity.

When your ignition is on, the gage shows the
temperature of the transmission fluid. The normal
