Chevy Suburban Engine Water Pumps

Along with the mechanical energy needed for motion, the powerful engine of your Chevy Suburban generates a lot of heat. Its cooling system is specifically designed to avoid overheating and keep the operating temperature within a certain range in which the engine performs best. To achieve it, the coolant has to circulate all the time while the motor is running, and a centrifugal pump is responsible for the forced fluid circulation. Driven by the crankshaft via pulleys, the pump has an impeller that changes its velocity depending on current RPM thus providing quicker or slower circulation.

Also, a belt-driven pump has a shaft that connects the impeller and pulley, and this shaft is supported by the bearings protected from an aggressive coolant through special seals. Whereas the impeller and pump housing are made of strong corrosion-resistant alloys, the pump's longevity greatly depends on the condition of these seals and bearings. In most models, there is a so-called control hole between these components; when you see the leakage from this hole, it means the sealing is bad, and coolant is likely to get to the bearings. Due to that, they may fail soon, and you don't have much time to replace the pump and avoid more serious damage. Check out our collection of Chevy Suburban water pumps for a quality replacement.
