- Driving Conditions: Vehicles used in harsh or demanding conditions, such as towing heavy loads or frequent high-speed driving, may require more frequent timing belt replacement.
- Maintenance History: If the timing belt has been well-maintained and inspected regularly, the replacement interval may be extended slightly.
