Fuel burning inside your engine creates combustion chamber temperatures that can reach 1000°F or more. For an engine to perform properly, the operating temperature must be controlled within a tight range. The cooling system regulates the engine temperature for maximum fuel economy, power, and component life as well as minimal emissions. Failure to maintain the cooling system often results in overheating which will eventually will cause a breakdown. The lifeblood of the cooling system is the coolant, it is a mixture of nitrates, water, and several other molecules mixed together. The normal operating temperature of a vehicle is higher than the boiling point of water which is why antifreeze is important. The nitrates and other molecules increase the boiling point of the mixture, which allows the antifreeze to maintain its liquid state. Proper maintenance of this system can help you to avoid getting stuck on the side of the road with an overheated engine.
