Pancho Posted January 14, 2021 Share Posted January 14, 2021 Hello everyone, I have a 2009 Mack Granite 10.8 L 660 CID L6 Mack MP7, and the shutoff valve that goes right on top of the coolant filter is leaking. I've been told that there is an o-ring in there and that all you have to do is "pull it out". Has anyone ever changed it out before, or does anyone have any helpful videos to show how it is done. Thank you. Quote Link to comment https://www.bigmacktrucks.com/topic/65533-first-time-working-on-a-2009-mack-granite/ Share on other sites More sharing options...
