Exactly OEM, works great. No gaskets anymore thank to GM being cheap, always replace the 3 orings and metal gasket, I didn’t and they leaked.

I installed this water pump on my LMM duramax 6000 km ago which was all heavy hauling, and it fit properly and has been working great.

Great replacement water pump. I would give it 5 stars if it came with a couple new o-rings for install. I had to dig into my old o-ring kit to install this. No big deal but for most DIY guys they’ll have to run and buy new o-rings.

It appears to be flawless casting should fit without a glitch. Since sold as a combo pump & housing already bolted together I assume the o-ring mating them together would have been installed!! Even though the specs say otherwise. Just to be safe, I'm pulling it apart!!
