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

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 cordless frother
Color: Black
This milk frother has been a great addition to my daily coffee routine. It comes with multiple useful accessories, which make it versatile for different drinks and easy to clean afterward. The motor is impressively powerful, producing rich, creamy foam in seconds. Exactly what you’d expect from a quality electric frother, which typically delivers fast, consistent results with minimal effort.
I also really appreciate the convenient charging base, which keeps everything organized and ready to go without dealing with loose cords. What stood out most, though, was the customer service. I had a minor issue with the buttons, and they quickly sent a replacement with no hassle. Overall, a reliable, well-designed product backed by excellent support.

Best frother for many reasons
Color: Black
I spent a long time searching for the right frother because of how much I would be using it. I make coffees, teas and protein shakes daily. I needed something more high powered than normal. Ive had others that just dont get the job done and/or dont last. (the 3 others I tried were all free gifts with a purchase of coffees or teas online. So now that i was paying for one, i wanted something better with all the good features)
Its has 3 attachments for every possible use (if u dont know what the hook one is for, its great for protein drinks or any heavier powders u need to mix) but honestly all 3 attachments work for heavier powders due to the stronger motor. U can use it for cooking as well. The stand charger is super convenient and space saving. Multiple power/level settings. Definitely a quality item but with a bargain price. The cherry on top is the customer service. They're great! responsive and very helpful. Im definitely happy with this purchase and will now be looking into see what other products they have to offer. 🙂

Excellent customer service and good product.
Color: Black
Really like this frother a lot, with the attachments. Great price and works well. That being said, it suddenly stopped working after a few months, to my dismay. However, upon reaching out to the company, they replaced it very quickly. So I do recommend it!

Great frother, dumb charger
Color: Black
Works well. I got this to replace my battery powered milk frother from IKEA. I use it to make a protein shake every day. I just take a 16oz glass, fill it halfway with milk, add a scoop of protein powder, and mix it with the frother, using a combo of low and medium power, but realistically, low is all you need for that purpose. Been using it everyday for the past almost month since I got it, haven't had to recharge it and it's still working great.
The only reason I'm giving 4 stars instead of 5 is because the charger is micro USB. Not using USB-C in 2025 is honestly just insulting. Change that and you have a 5-star product.
