Timing Belt: The F8 is generally a non-interference engine (valves don't hit pistons if the belt breaks), but the belt should be replaced every 60,000 to 100,000 km to avoid breakdown.
Valve Clearance: For models without hydraulic lifters, adjust every 60,000–80,000 km.
Cooling System: Flush and replace coolant every 2 years to prevent overheating, which can lead to head gasket failure. Key Torque Specifications If you want a free but less verified
