Your Duramax isn't going to last long with a failed water pump, so why delay replacing it? Eastern Industries provides a low-cost OE style replacement solution for your 2006-2016 6.6L. Providing the pump side and not the housing side, you have a cost friendly way to get your GM back on the road sooner. All the o-rings and gaskets are included, so you can get your truck right back to work. With an aluminum case and polymer impeller, you get the same OE style part, without the bits you don't need so you can yourself a little extra cash.
