What does a water pump do?

This water pump functions as a vital component of the engine cooling system, ensuring the continuous circulation of coolant between the engine block, cylinder head, and radiator. By maintaining steady fluid movement, it prevents thermal buildup and protects engine components from excessive heat during heavy-duty operations.
