Mitsubishi Galant Fortis Head Gasket Malaysia
Head gasket failure on the Galant Fortis 4B11 is not common if the cooling system has been maintained, but it becomes a risk on high-mileage units that have suffered overheating events. Signs include white smoke from the exhaust, milky engine oil, coolant consumption without visible leaks, and bubbling in the coolant reservoir. A head gasket repair is a significant undertaking — on a high-mileage, low-value vehicle, owners should weigh repair cost against vehicle value carefully before proceeding.
