If your water pump is starting to fail, you may notice coolant leaks, or even hear a whining noise coming from the engine. If you think your water pump is starting to fail, replace it as soon as you can.

The water pump in your car is driven by the accessory belt, and if left alone for too long a broken water pump could cause a lot of damage to your engine. It is also a good idea to replace your accessory belt while replacing your water pump, as well as gaskets and pulleys.
