Timing Belt Replacement Due
Critical — Stop driving
What It Means
The timing belt replacement interval has been reached. This is a critical maintenance item — if the timing belt breaks while driving, the engine will suffer catastrophic damage (pistons hitting valves) on interference engines. Most vehicles require timing belt replacement every 60,000-105,000 miles.
Common Causes
- Scheduled maintenance interval reached (check owner's manual for your vehicle's interval)
- Timing belt tensioner failing (noise from belt area)
Can I Still Drive?
No — schedule replacement immediately. If you hear a slapping or rattling noise from the timing cover area, the belt tensioner is failing and the belt could snap at any moment. Tow to a shop if noise is present. Replace the water pump at the same time (driven by the timing belt on most engines).
