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. The water pump is responsible for keeping
coolant flowing throughout your engine, keeping it cool. As your Chevy/GMC

age. If you do not have your coolant flushed at the recommended factory
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.

Great Value & Eco-Friendly!
Color: Brown, Size: 9inch
I love these paper plates! They’re sturdy, affordable, and perfect for everyday use. I actually have them on an auto subscription every two weeks because we use them so often. I also love that they’re biodegradable, which makes them an even better choice for our family. Definitely a great value for the price!

Great quality. 6” plate. 4.5” eating surface
Color: Brown, Size: 6inch, Color: Brown, Size: 6inch
Love the quality. No waxy feeling, ,but has a slight seal on a cardboard plate so food does not make plate soggy. I give a 4 star because, the actual surface that is usable for food is 4.5”. This can be a nice thing as the edge holds food / snack on plate.. Reasonably priced for 100 small plates. Would I buy again maybe.
