Since you've had to replace the intake manifold gaskets (I hope you did upper and lower if it's a 3.8L) I suspect that the previous owner used some kind of stop leak "goop" to stop the manifold from leaking. I'd suggest using a good quality cooling system cleaner such as Prestone Super Flush or GM part number 10-5037 (19286424). BUT be prepared for something to spring a leak. Depending on how much stop leak "goop" is in there a radiator replacement may also be needed to solve the problem. HTH. -Jim


Thank You Very Much! It comes to find out the whole problem was the reserve radiator overflow was no good along with pressure cap Only about 800 Later! But thanks anyways appreciate!

possibly a faulty water pump, or could also be a plugged radiator. Make sure the cooling fans are coming on. Grand ams are notorious for intake and Headgasket leaks
