Your engine creates considerable heat generating the energy necessary to move your vehicle and power all its electrical systems. Exceeding the temperature range your engine was designed to operate within can have broad and long-lasting consequences on the longevity of your engine. Whether your engine runs a little hot on a consistent basis, or infrequently experiences overheating, problems with overheating generally are a result of a failure in your cooling system.
The cooling system in your engine is designed to keep your engine in its ideal operating temperature. It is there to ensure that the heat your engine generates is kept from reaching dangerous temperatures. Consisting primarily of your radiators, hoses, and coolant fluid; regular investments of a little time and energy into maintaining these components will go a long way to ensuring the longevity and consistent reliability of your vehicle.
