How does antifreeze work in a car engine?

Although water is able to hold some of an engine’s heat, most engines require a mixture of water and chemicals, more commonly known as antifreeze. This product is a crucial component of the cooling system, as it helps the car operate in a variety of temperatures, from the frigid cold to the scorching heat.

What happens to car cooling system in hot weather?

Cooling systems rely on coolant/antifreeze to keep all parts of the engine cool. On a hot day, this liquid runs around the engine at a higher temperature, causing some parts of the engine to overheat and fail.

How does the coolant in an engine work?

As the temperature outside changes from hot to cold coolant is pumped throughout the engine block to maintain an even operating temperature. Antifreeze does more than just regulate temperature, however. Maintaining proper fluid levels also helps to prevent corrosion. How Does Engine Coolant Work?

How can you tell if your car has coolant or antifreeze?

If you notice a dip in recorded MPG, check your coolant level and watch the temperature gauge for signs of overheating. A sweet smell – Coolant/antifreeze has a distinct, sweet odour. If it leaks out of the cooling system, you may be able to smell it in the cabin, particularly if the engine is hot.

How does the coolant work on a car?

The cooling system on modern cars is fairly straightforward. A network of passages carry liquid antifreeze/coolant around the hotter parts of the engine. The coolant is forced around the passages by a water pump. A thermostat prevents the coolant from flowing until the motor gets warm enough.
