Plymouth Voyager Head Gasket May Fail Prematurely
Plymouth Voyager Problem
Engine Affected: 2.4L 4 Cylinder
Visitor, 1998 Plymouth Voyager, 2.4L 4 Cylinder
Not fixed yet. Anti freeze in transmission fluid. Replaced radiator, flushed transmission, then told its the head gasket. Should I try to use a product to plug leak or replace?
