What does a water pump do?

This water pump serves as a critical component within the engine cooling system, functioning as a centrifugal-type pump to circulate coolant between the engine block, cylinder head, and radiator. By maintaining constant fluid movement, it prevents thermal buildup and ensures the engine operates within safe temperature parameters even under heavy commercial vehicle loads.
