What does a water pump do?

A water pump is a critical component of the engine cooling system that continuously circulates coolant between the engine block and the radiator to prevent overheating. This belt-driven mechanical pump is engineered to withstand heavy-duty thermal loads and maintains stable coolant flow throughout the engine's operating cycle.
