When should you change your 09 Chevy silverado timing chain?

The 2009 Chevy Silverado doesn't have a timing chain; it uses a timing belt. Timing chains are generally much more durable and don't require replacement nearly as often as belts.

The recommended replacement interval for the timing belt on a 2009 Chevy Silverado depends on the engine and your driving habits, but it's typically around 100,000 miles or 10 years, whichever comes first. Always consult your owner's manual for the specific recommendation for your vehicle's engine. Ignoring this can lead to catastrophic engine failure.
