Essentially a thermometer -- tells the temperature of the engine. Overheating
can ruin you engine, not to mention boil off all your antifreeze.
Fortunately, if you shut the engine down soon after if gets too hot, no harm is done.
Boiling off the antifreeze cools the engine, so you are not likely to damage it until
your radiator boils dry. Obviously, overheating is caused by failure of the cooling system-
usually a radiator leak or failure of the water pump.
Some cars have a gauge that tells the temperature-- others have only an "idiot light"-
something that turns red if the temperature is dangerously high.
