Does a new timing belt have a break-in period?

[MacKylie]

New timing belts do have a break-in period, as all components require some initial wear-in. Automakers explicitly specify that the timing drive system should be replaced every 60,000 kilometers. Damage to timing drive system components can cause vehicle breakdowns while driving, and in severe cases, may lead to engine damage. Replacement should not exceed 80,000 kilometers or 3 years to prevent belt aging and breakage. Different vehicle manufacturers have varying maintenance cycles, so the specific replacement interval should follow the automaker's recommendations. Proper engine operation relies on precise timing coordination between components, such as valve opening/closing timing and spark plug ignition timing, which is ensured by the engine's timing system.
