Asked by Mar 01, 2015 at 05:10 PM about the 1998 Buick LeSabre Custom

Question type: Maintenance & Repair

Coolant has been having to be filled at
least once a month

1 Answer


It's most likely going to be the intake manifold gaskets. These engines are notorious for this. Have the upper and lower intake manifold gaskets replaced. Then have the shop change the oil twice after the repair. This will remove the coolant contamination from the crankcase and prevent a spun bearing. They'll have to inspect the upper intake for cracks as well. It's made out of plastic and prone to cracking. HTH. -Jim
