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 40,000 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.
The 100,000 km service (commonly called the '100k service') is a major milestone for any car. By this point, a number of wear items reach the end of their designed lifespan simultaneously. Getting the service right saves you from multiple failures in the following 50,000 km.
What the 100k service should include
- Engine oil & filter — fresh full synthetic with correct spec for your engine
- Spark plugs — iridium or platinum plugs are due by 80,000–100,000 km
- Air filter (engine and cabin) — both typically due at this interval
- Coolant flush — glycol breaks down over 2–3 years, causing internal corrosion
- Brake fluid — hygroscopic fluid absorbs moisture, lowering boil point
- Transmission fluid (if auto) — ATF degrades and causes shift quality issues
- Drive belts inspection — timing belt replacement if due (critical!)
- Tyre rotation and alignment check
Estimated cost at 4M Car Care
A full 100k service (excluding transmission fluid if the car is under 60,000 km ATF change) typically runs RM 600–1,500 depending on your car's engine oil specification and whether spark plugs are due. European cars cost more due to oil spec and part prices.
We provide a detailed inspection report with your 100k service — any upcoming issues are flagged so you can budget and plan rather than face unexpected breakdowns.
