Model Years Affected: 1998, 1999, 2001

Engine Affected: 3.8L V6

Average Mileage: 141,687 mi (89,000 mi - 190,000 mi)


The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
