intervals, you could see premature failure of your water pump. This

pump replaced with factory-like components.

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.
