Re: 2003 head issue

12-30-16 I still don't have any coolant loss the truck is running quiet heat still works the oil pressure gauge is still very responsive to the throttle. those ac delco coolant tablets 100% stopped my coolant loss into the oil. I was adding coolant frequently and haven't added a drop since my last post I emailed gm about the casteck heads and they played dumb.
