If you are refering to the 3.1L GM engine having a problem? yes. The lower intake manifolds are notorious for leaking at the coolant jackets because of gasket degradation. There is a seller on ebay who has a aluminum reinforced gasket for sale. They leak. leak leak. Is it your current leak? I dont know, I would have to see the car for myself. Change the coolant out once a year.Usually unless you have flushed the system right when you got the car, the dexcool has eaten up the plastic intake manifold gasket. There has already been a lawsuit about this. Me personally Im going to try the aluminum reinforced gasket.
