[Kai]

The timing chain on the Roewe 350 is recommended to be replaced every 150,000 kilometers. Below are the relevant details: 1. Function of the timing belt: The main function of the engine timing belt is to drive the engine's valve train, ensuring that the intake and exhaust valves open and close at the appropriate times to allow the engine cylinders to properly intake and exhaust air. 2. Common issue with the Roewe 350 timing chain: The common issue with the SAIC Roewe 350 timing chain is "unexplained elongation," which is a frequent problem with this model and typically appears after about four years of use. Many users have reported this issue, with most experiencing it after four years or 45,000 kilometers. The engine in this vehicle has inherent defects, and the timing chain is a significant design flaw. 3. Symptoms of the timing chain issue: Symptoms include difficulty starting the engine when cold and a "rumbling" noise from the engine when accelerating. Generally, timing chains are maintenance-free components, but this common issue usually manifests after four years of use, often outside the warranty period.
