Me Too

Model Year Affected: 2001

There was a problem with porous cylinder head castings that allowed oil to leak into the coolant. The low oil pressure light would come on intermittently due to low oil level and excessive oil could be found in the coolant reservoir. A new cylinder head would be needed.
