What is a cooling system?
The cooling system helps regulate the amount of heat in the engine. For example, a typical 4- cylinder vehicle cruising along the highway at around 50 miles per hour, will produce 4000 controlled explosions per minute inside the engine as the spark plugs ignite the fuel in each cylinder to propel the vehicle down the road. These explosions produce an enormous amount of heat and, if not controlled, will destroy an engine in a matter of minutes. Controlling these high-temperatures is the job of the cooling system.
The second job of the cooling system is to maintain the engine at a constant temperature whether the outside air temperature is 110 degrees Fahrenheit or 10 below zero. If the engine temperature is too low, fuel economy will suffer, and emissions will rise. If the temperature is too hot for too long, the engine will self- destruct.
Almost all automobiles use liquid coolant to cool the engine. The cooling system circulates liquid coolant through the engine absorbing heat, then out to the radiator to be cooled by the air stream coming through the front grill of the vehicle.
The number one job of the cooling system is to keep your engine cool. Our number one job is to keep you on the road.
