TIBAO Water Pump for 1RZ, 2RZ, and 4Y.

The water pump for 1RZ, 2RZ, and 4Y engines is a belt-driven component responsible for circulating coolant to regulate engine temperature. Made of aluminum or cast iron, it ensures efficient cooling by maintaining proper coolant flow through the radiator and engine block. A failing pump can cause overheating, coolant leaks, and unusual noises, leading to potential engine damage. Regular inspection and timely replacement with a quality OEM or aftermarket pump are essential for maintaining engine performance and longevity.
