When do you replace the timing chain on the 2006 Suzuki XL 7?

The timing chain on a 2006 Suzuki XL-7 is designed to last the lifetime of the engine and typically does not require replacement unless there are signs of wear or failure. However, it's wise to inspect it during regular maintenance, especially if the vehicle has high mileage (over 100,000 miles). If you notice any symptoms like unusual noises from the engine or a check engine light related to timing issues, it may be time to have it checked or replaced. Always refer to the owner's manual for specific recommendations.
