Mitsubishi Galant Fortis Coolant Service Malaysia
The Galant Fortis 4B11 engine uses a standard long-life coolant (LLC). In Malaysia's tropical climate, coolant should be inspected every 40,000 km and replaced every 80,000–100,000 km or if discoloured. High-mileage units should have the cooling system inspected for hose condition, thermostat function, and radiator integrity at the same time. Neglected coolant becomes acidic and can cause internal corrosion to the aluminium engine block and radiator.
