I joined last week after finding this site as a search for help on my adult daughter's '08 Grand Prix, which was leaking coolant. I'm a retired Ironworker from southeast Missouri, and my daughter and her three kids are going through a divorce, so I'm trying to make sure she stays on the road (she works long shifts as a nurse), and keep them all safe. My problem started with a shop radiator/engine flush that produced a leak and they said it was probably the timing cover, so I elected to try the pump and elbows first, and crank the timing bolts while I was at it. With the help of a lot of guys on this forum, I navigated my way through this job. It went quick and easy, until I sheared a short bolt while torqueing it to spec. Took it off a second time and backed the bolt out, then ruined the paper gasket putting it back in. Didn't catch that till I was done (again) and topping off the coolant. Third time was a charm with a new metal gasket. Now I think I have brakes to replace. Thanks for a great forum with great members who helped me out fast and without commenting on my ignorance of this engine's quirks. My daily driver is a '51 Chevy 3100 pickup, which is a whole other wrenching experience from these 3.8's. I just hope I can help somebody else on here at least once. Lee Butcher, Park Hills, Missouri
