Observing and responding to the warning signs of a failing water pump can help prevent costly damage to the engine. High-pitched squealing and whining from the bearings wearing out are among the first signals that your pump is starting to deteriorate. It may even sound like the whine of a serpentine belt, and could actually be both the water pump and the belt if pump failure has started affecting other components.

If your water pump is indeed giving out, there will most likely also be visual signs. Be sure to check for coolant leaks on or under the engine as well as corrosion or rust on the pump itself. A coolant leak can be recognized by its bright color (typically variations of blue, green, pink, yellow, or orange) and sweet aroma, which help distinguish it from other types of fluids you may encounter, like water or a transmission leak.

Catching and replacing a failing water pump as early as possible can prevent you from needing more costly repairs. If a deteriorating pump is left alone, it could force you into premature coolant replacement, gasket repairs, and more extensive work that will undoubtedly cost more than the pump. Regularly checking your car’s coolant level and the pump’s belt tightness will help ward off pump failure and keep your car free of that pesky whining, so you can jam out in peace.
