The water pump is of good quality and was a perfect fit for a lmm duramax. I would definitely recommend it. However, the upper O-ring seemed slightly large, and when installing the bypass tube, it caused the O-ring to get cut. Other than that, I have put 1,000 miles on the water pump with no issues

More money and far less quality than the GM genuine pump when laid side by side. Also the gasket to the oil cooler is paper, not oem quality, and needs to be metal/silicone. Very poorly made Chinese pump.. not that it matters, as it was damaged so badly from poor packaging during shipping that its completely unusable now. In the one picture, the GM pump is closest to the camera, acdelco on the top
