How many kilometers should the timing chain of the Malibu be replaced?

The timing chain of the 2014 Malibu should be replaced every 150,000 to 200,000 kilometers. 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 will accelerate wear and reduce the lifespan of the timing chain. The 2014 Malibu has a length of 4869mm, width of 1854mm, height of 1472mm, and a wheelbase of 2737mm. It is equipped with a 6-speed automatic transmission. The maximum torque of the 2014 Malibu is 190 Nm, the top speed is 197 km/h, the fuel tank capacity is 70L, and the maximum horsepower is 154 hp. The front suspension is a MacPherson independent suspension, the rear suspension is a multi-link independent suspension, and the tire specification is 225/55R17.
I used to work in a repair shop and came across many Malibus. Its timing chain is generally designed to be maintenance-free for life, unlike belts that require regular replacement. The manual doesn't specify a fixed mileage interval, but experience suggests checking the chain condition around 100,000 kilometers. If the chain is worn or loose, it can produce rattling noises and even lead to engine failure, resulting in major repairs costing thousands of dollars. Don't wait for problems to arise before panicking. Regular maintenance, including having the mechanic listen for unusual noises and adjust the tension, can save a lot of trouble. The durability of the chain depends on driving habits—frequent high-speed driving or heavy loads may accelerate aging. Regular inspections can prevent unexpected breakdowns.
I've been driving my Malibu for five years and haven't specifically replaced the chain. Consulting the manual, it says the chain is mainly for inspection and not mandatory for replacement. Generally, pay attention around 100,000 kilometers to see if there's engine shaking or power loss. If the chain is normal, you don't need to waste money. But if it breaks, repairs will take time and money. I get a comprehensive vehicle inspection every 100,000 kilometers, including the chain part. Prevention is better than regret. The money saved can be used for gas on long trips, which is more cost-effective. A stable chain is crucial for daily commuting.
