TIBAO Water Pump for Toyota Sienna 1MZ-FE, 2MZ-FE, and 3MZ-FE.

The water pump for Toyota Sienna models with 1MZ-FE, 2MZ-FE, and 3MZ-FE engines is essential for maintaining proper cooling by circulating coolant through the engine. Typically made of aluminum, it is driven by either the timing belt (1MZ, 2MZ) or the serpentine belt (3MZ). A failing pump can cause overheating, coolant leaks, and engine damage, so timely replacement is crucial.
