The Water Pump in Buick Century cars circulates the coolant from the car's radiator to the engine in order to allow the fluid to absorb heat produced in the combustion chamber. A belt-driven pump and an impeller within this pump circulate the coolant within the network of passages in the cylinder head and block are an element of most models. Previous designs were based on cast iron water pumps, and now they remain in aluminum casting; several cars today have electric water pumps for better performance. Some of the signs include, leaks in the cooler, squealing noise that originates from the bearings and excessive heating of the engine. There are performance water pumps specifically made for high-performance engines, these pumps have higher coolant flow rates and lower power demands than the mainstream water pumps.
