Review on ACDelco 12669488 Original Equipment Vacuum by Brandon Addison

The product fully corresponds to the description. This was for my 2016 GMC Sierra 1500 with a 5.3 engine. Didn't make any noise, didn't break, I just did it as a preventive measure as I've heard stories on the forums about removing the engine when it explodes. I have basic hand tools and this took me about 3 hours. The vacuum pump comes with gasket and bolts, again a perfect component and I ran the truck with the new pump for several days with no problems.
