Engine Coolant CHECKS

摘要

An engine's cooling system usually consists of a water-based liquid that flows around waterways inside the engine. The liquid is air-cooled by an external radiator and recirculated by a mechanical pump to help maintain the engine's temperature. The liquid coolant is a mixture of water and antifreeze, which helps to prevent it freezing in cold weather and causing internal damage. It also helps to prevent internal corrosion throughout the year and overheating in hot weather.
