The more it works and runs, the hotter it gets! If it doesn't cool down, the eventual overheating will cause your engine to break down and damage other components of the vehicles engine. To cool it down, the cooling system activates as soon as it's told to in order to circulate coolant, a specialized fluid to cool down the engine.
Now for the fun part ... how it works!
The cooling system is made up of MANY parts and works much like the human circulatory system!
The essential brain of the whole system is the thermostat! The thermostat is what measures the temperature of the fluid (coolant) in the engine block.
Once that fluid gets to a predetermined temperature the thermostat opens, allowing the water pump (the heart of the cooling system) to push cooled coolant to the engine block, out of the engine block through a hose, through the radiator (where it passes through little ribs that are cooled down by the forced air that goes through it when you drive) and back to the engine through another hose where it continues to circulate and cool. Once the engine gets back down to a cooled temperature, the thermostat closes and that fluid circulation from the engine to the radiator and back to the engine stops!
With the hot weather here, this is one of the systems you'll want to have checked when you have your vehicle in for summer maintenance! Just like all the other fluids in your vehicle, your coolant needs to be checked for condition as well as level. If it is old fluid, it won't do a proper job of cooling your engine and it should be changed out.
