How many kilometers should the timing chain of Baojun be replaced?
2 Answers
The replacement cycle for the timing chain of Baojun is approximately 150,000 to 200,000 kilometers, depending on the actual usage of the vehicle. Maintenance of the car's timing chain: If the car uses a timing chain, compared to a timing belt, the timing chain has a longer service life and lower failure rate, but it is not maintenance-free for life. During engine operation, there will be wear between the timing chain and the sprocket, and it also has a certain service life. The timing chain is lubricated by engine oil. If the engine oil is not changed for a long time or the oil quality is poor, it can easily accelerate wear and reduce the lifespan of the timing chain. Effects of a damaged car timing chain: When the timing chain needs to be replaced, it will not break immediately but will gradually stretch, leading to chain skipping. This may cause valve interference, mainly resulting in engine instability, lack of power during acceleration, and the engine fault light turning on, among other issues.
I've been driving my Baojun car for several years, and the timing chain replacement shouldn't be based solely on a fixed mileage. Generally, the manufacturer's manual recommends replacement between 100,000 to 150,000 kilometers, but I personally changed mine at 120,000 kilometers because I heard slight abnormal engine noises during a long-distance trip and got it checked. Actually, the chain's lifespan depends on driving habits: if you frequently drive on highways or encounter urban traffic congestion, wear will be faster, requiring earlier attention. Additionally, maintenance records are crucial: regular oil changes ensure better chain lubrication and extend its service life. Never delay replacement—if the chain loosens or breaks, it could severely damage the engine, leading to much costlier repairs. I recommend Baojun owners visit a repair shop every 50,000 kilometers to check for unusual sounds—safety first.
