If your water pump fails, it's a disaster! A water pump is in charge of making sure your engine stays cool by keeping the coolant flowing. As your Duramax ages, the factory water pump breaks down from old age. If you don't flush your coolant when the factory says to, your water pump could give out too soon. This kit for 2006-2016 GM Duramax water pumps (including cover and seals!) is the perfect way to replace your old one with factory-like parts.

How Do I Know If My Duramax Water Pump Is Bad?

When a water pump starts 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 water pump designed to leak coolant in failure situations. You may also notice rust or deposit buildup on the water pump in more extreme cases. A loose water pump pulley or a water pump that is making whining noises can occur, but is less common. Lastly, if your truck is overheating, your water pump is one of the many culprits you will need to check when diagnosing why your truck is overheating.
