The Merchant Automotive 10549 Water Pump (With Housing) is a high-quality replacement for the worn water pump your 2001-2005 GM 6.6L Duramax LB7/LLY. Water pumps are common wear items not only in diesel trucks, but in all vehicles. A failing water pump can cause catastrophic damage if not taken care of early.

Signs The Water Pump In Your Duramax Is Bad
There are a few tell-tell signs to indicate that you need to replace your water pump as soon as possible. Fortunately, 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 can also be the culprit and you will want to check when diagnosing why your truck.

Note:
The harmonic balancer balancer bolt will need to be removed to replace your water pump.
The factory bolt is a torque-to-yield fastener (TTY) for one time use and must be replaced.
