Is there a timing belt or chain in the 2009 Chevrolet Impala?

Question

Accepted Answer

The 2009 Chevy Impala comes with a timing chain, which is different from a timing belt. Timing belts typically need to be replaced every 60,000-100,000 miles, but the Impala's timing chain is made to last the whole lifespan of the vehicle without needing maintenance. Unlike belts, metal chains are more durable, do not crack or dry out, and can even help improve fuel efficiency. Chains are better protected as they operate from inside the engine rather than outside. However, if a chain breaks, it can cause serious damage to the engine. If you notice metal shavings in the oil, experience misfiring, or hear rattling sounds while idling, it's important to have the chain inspected by a mechanic.
