Water pumps are common wear items not only in Duramax trucks but in all vehicles. A failing pump can cause catastrophic damage if not taken care of early. The water pump is what is responsible for keeping coolant flowing throughout your engine, keeping it cool. As your Duramax gets older, the factory component can start to deteriorate due to old age. If you do not have your coolant flushed at the recommended factory intervals, you could see the premature failure of your coolant pump. This 2001-2005 GM Duramax water pump kit w/ cover is a great way to get your pump replaced with factory-like components.

How Do I Know If My Duramax Water Pump Is Bad?
When water pumps start to fail, there are a few tell-tell signs to indicate that you need to replace your water pump as soon as possible. Luckily, most water pumps will show symptoms of failing before they completely fail. This may include a coolant leak from the weep hole, a small hole in the housing, designed to leak coolant in failure situations. You may also notice rust or deposit buildup on the internal impellor in more extreme cases. A loose pulley or a pump that is making whining noises can occur, but is less common. Lastly, if your truck is overheating, this is one of the many culprits you will need to check when diagnosing why your truck is overheating.
