Two problems related to coolant leaking have been reported for the 1998 Oldsmobile Silhouette. The most recently reported issues are listed below.
My 1998 olds minivan started to over heat while my wife was transporting our children and foster children. When this happens she must pull over to let the engine cool creating a safety hazard. The Oldsmobile dealer says the intake gasket is leaking coolant and the repair cost is over $600. I have learned this is manufacturing defect that gm has had many complaints on.
