This gage shows the engine coolant temperature.

It also provides an indicator of how hard the vehicle is working. During a majority of the operation, the gage reads 210° F (100° C) or less. If a load is being pulled or going up hills, it is normal for the temperature to fluctuate and go over the 235° F (113° C) mark. However, if the gage reaches the 260° F (125° C) mark, it indicates that the cooling system is working beyond its capacity.
