Your Infiniti water pump's design was based on laws of fluid dynamics. Remember your high school physics class? Those same concepts can be applied to help understand your water pump and diagnose its problems. The Infiniti water pump is designed as a rotary dynamic pump. The design, also known as a centrifugal pump, depends on the impeller to force the coolant fluid to rotate. Under that force, the fluid moves around under its own momentum. While the fluid is spinning around, the power of the pump's centrifugal force sends the water out of the pump, while the fluid is continuously drawn from the center. The fluid is then pushed through the Infiniti engine: the fluid returns from the radiator and hits the pump vanes. Then, the pump vanes move the water outside of the pump to the engine. In the engine, the fluid flows to the engine block, cylinder head, radiator and ending up back at the pump. Without that fluid circulation created by your properly running Infiniti water pump, your car will overheat and wreak damage to the entire engine system. At that point, you will face hundreds, if not thousands, in engine repair expenses. So save yourself some major engine repair bills by ensuring you have enough coolant and water in your system, and checking your hoses regularly for leaks. You will lengthen the lifespan of your Infiniti water pump, and keep your engine running smoothly.
