A coolant pump, also known as a water pump, is a crucial component of a vehicle's cooling system. Its primary function is to circulate coolant (usually a mixture of water and antifreeze) throughout the engine to regulate its temperature. Here's how it works: Cooling System: Modern internal combustion engines generate a significant amount of heat during operation. If this heat is not properly managed, it can lead to engine damage or even failure. To prevent this, vehicles are equipped with a cooling system. Coolant: The coolant used in the cooling system is a mixture of water and antifreeze. This mixture has a higher boiling point and lower freezing point than water alone, making it effective at maintaining a stable temperature range. Circulation: The coolant pump is responsible for circulating the coolant throughout the engine and the radiator. It is typically driven by a belt connected to the engine's crankshaft or by an electric motor. Cooling Process: As the engine run
