The temperature gauge shows the coolant temperature and warns if the engine is overheating. Overheating can be extremely bad for a car. Many head gaskets have been blown or cracked by overheating issues. These are not cheap repairs, therefore, be vigilant and watch the temperature gauge.

It is very important to monitor the temperature gauge to be sure that your engine is not overheating. If you notice that the gauge is reading much hotter than it usually is and the outside temperature is not unusually hot, have the cooling system checked as soon as possible.

Note: If the temperature gauge moves all the way to hot, or if the temperature warning light comes on, the engine is overheating! Safely pull off the road and turn the engine off and let it cool. An overheating engine can quickly cause serious engine damage!
