Coolants and Antifreeze. What is a coolant?


What is a coolant?
Acoolant (also called an antifreeze) is a special fluid that runs through your engine to keep it within its correct operating temperature range. It is made from either ethylene glycol or propylene and is usually green, blue or even pink in colour.

How does a coolant work?
Your car’s engine produces a lot of heat when it is running and must be cooled continuously to avoid engine damage. The cooling system in your car works by sending the coolant through passages in the engine block and heads. As the coolant flows through these passages, it picks up heat from the engine. The heated fluid then makes its way through a rubber hose to the radiator in the front of the car. As it flows through the thin tubes in the radiator, the hot liquid is cooled by the air stream entering the engine compartment from the grill in front of the car.Once the fluid is cooled, it returns to the engine to absorb more heat.The water pump has the job of keeping the fluid moving through this system of plumbing and hidden passages.

Why Coolant is Important
Without a coolant, the heat produced through constant internal combustion would destroy the engine very quickly. Water alone is not enough to keep the system cool, for the high temperatures inside the motor would eventually boil it off. In time, the water in the system would evaporate entirely. Likewise, in very cold weather, the water would freeze when the car sat idle, rendering the cooling system useless.
