Timing chain change interval | 200,000 km (recommended) Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur. |
