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 gets older, the factory water pump can start to deteriorate due to old age. If you do not have your coolant flushed at the recommended factory intervals, you could see premature failure of your water pump.

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 wrestle or chewing toy for your pet.
Color: brown1
My 4 legged "little boy" loves to play, even at 10 years old but is getting a tad "over the hill" for chasing a ball. This toy has brought him (and me) many hours of fun as it can be played with in the house without chance breaking something (it is soft) and was fairly well thought out - being made with the "squeeker" in one end, and a couple of ropes sewn in to provide a "tug of war" when he is really feeling frisky. I've had it around 6 months and it has only incurred minor damage and really just normal wear and tear considering what it has gone thru. A great toy for the price that your pet may play with by itself, or one you can use to wrestle with it so you can be part of the action. When this one is finally torn apart, I will be buying another one (if the dog out lasts it), or I will bury my pet with this one if it out lasts him. It's that special.

Dog toy for heavy chewers
Color: brown1
This is pretty durable. My puppy chews up most stuffed toys. This one is still mostly intact. It’s missing one ear and the tail but the way it was sewn it’s still very usable. It’s one of his favorite toys
