Mitsubishi Galant Fortis 100,000 km Service Malaysia
The 100,000 km service is a major milestone for the Galant Fortis. Key items to address: spark plug replacement (iridium, 4 pcs), timing chain and VVT actuator inspection, CVT fluid change (if not done within the last 20,000 km), full brake system inspection, suspension and bushing check, coolant replacement, and throttle body cleaning. Many units on Malaysian roads are now at 150,000–200,000 km — if the car has no service history, performing a comprehensive catch-up service is the right starting point before addressing any specific faults.
