Engine overheating can be caused by any number of problems, large or small. The most obvious is a lack of water or antifreeze in your car. Without coolant, your car will (naturally) overheat. Usually if an engine is overheating it is accompanied by white smoke coming from under the hood by your cylinders, (below your spark plugs). White smoke is steam, and is usually burning antifreeze or water that has leaked into your cylinders and is being combusted along with the air and gasoline. One possible cause of this is a melted / old / worn head gasket. That was my problem :). You should let the car cool completely, so you do not burn yourself, then check the coolant level inside the engine. You MUST wait until the car's engine is cool, because the temperatures in an engine can reach over the boiling point of water, and if you open the cap to check the water levels, and the steam rushes out, you risk burning or blinding yourself. Other than that, i'd advise talking to a professional, or a engine-inclined friend for a more through inspection. Good luck!
low coolant or sticking thermostat
I would say no.
If it comes on it means the temperature of your engine is too hot. Your engine is overheating.
The enigine is running too hot...
There will be a light that comes on situated in the dashboard.
It comes from the hot wire harness from the battery through the fuse panel. It will have a fuse in the main fuse block.

Was the car actually running hot? Is there water in the oil? You could have a weak head gasket that starts to lek under driving conditions. Get it in the shop before you crack a head. If the car is running hot, does it over heat while driving or will it overheat at a stop? If it does it will driving, check your trans fluid. About half of nuisance overheating can be traced back to the trans fluid cooler in the radiator.
These cars are very bad about the water pump impeller braking. Then there would be no water flow. They will get hot pretty quick so be careful Ron Randall
It means that you engine is overheating. Check your water coolant level and oil levels. DO NOT continue to drive the car until the problem is resolved, an over hot engine will cease and after that happens you will need a new engine.

The engine is overheating - see a mechanic for a professional diagnosis .
