Function and Role

• Coolant Circulation: Driven by the engine's timing belt or accessory drive system, this pump forces coolant to continuously flow through the engine block, cylinder head, and radiator to maintain optimal operating temperatures.

• Maintenance Note: Water pumps on these multi-valve micro-engines are typically replaced during timing belt service intervals to prevent bearing failure, coolant leaks, or subsequent engine overheating.
