What does a water pump do?

This water pump serves as a critical component within the engine cooling system, ensuring the continuous circulation of coolant between the engine block and the radiator. By maintaining consistent flow, it helps the engine reach and hold its ideal operating temperature, which is vital for preventing overheating during long-haul transport or high-load operations.
