This is called the Temperature light or gauge
There will be a light that comes on situated in the dashboard.
It is normal to boil when you turn the car off. When the coolant stops flowing, the coolant in the hot engine boils and pushes steam out of the engine. The recovery tank collects the excess and allows it to go back in when the engine cools.

The engine coolant temperature sensor is probably at fault.
The coolant expands and rises when it is hot so it goes up, the coolant comes down when the car is cold.
Lack of coolant, faulty thermostat, radiator fan not working...
When your car smells like the engine is hot, is the engine hot? If it smells hot and the engine is not hot, then you have coolant escaping onto a hot surface. You may have bad radiator hoses, a leaky radiator, a blown gasket, or some other problem. You need to find the leak.
Off and cooled down. Putting cold coolant into a hot block can crack it. And it can damage the radiator, as well as spitting the coolant back at you.
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.
A fan in a car usually starts running as soon as your car engine gets hot enough for it to be of any benefit. This depends on weather, oil level, coolant level and quality and engine speed. Generally, a car in a hot climate with poor oil and coolant and a high running speed gets hotter quicker.
Your car can only create cold air if the engine is running to make the coolant work correctly. If your car is idle, your engine is still hot but your engine isn't running so the air you are receiving is actually air heated by the engine.
In a Chevy Lumina, low coolant means that the car needs more anti-freeze/coolant added. This is needed to keep the engine from getting too hot
