What does a water pump do?

The water pump is a vital component of the engine cooling system, responsible for circulating coolant between the engine block, cylinder head, and radiator. By maintaining constant fluid movement, this part prevents engine overheating and ensures stable operating temperatures for heavy commercial vehicle engines.
