Engine Coolant Temperature Gage

It can be used to see when your engine has
warmed up and to make sure your cooling system
is operating properly. If the gage pointer moves
into the shaded area, the engine coolant is too hot
and the engine coolant temperature warning
light will come on. See Engine Overheating on
page 369 for more information.
This gage shows the
