Regulates Engine Temperature
Absorbs heat from the engine.
Transfers that heat to the radiator, where it's released into the air.
Prevents Overheating
Stops the engine from getting too hot during operation.
Crucial in hot climates or under heavy engine loads.
Prevents Freezing
Keeps coolant from freezing in cold temperatures (thanks to antifreeze content).
Prevents engine block cracking in freezing weather.
Prevents Corrosion
Contains corrosion inhibitors to protect the radiator, water pump, and engine block from rust and scale buildup.
Lubricates Water Pump and Seals
Reduces wear on internal components in the cooling system.
