When to replace timing chain on 2003 Dodge Grand Caravan SE 3.3L 6 cyl?

Hi, this is Bo, an auto expert on RepairPal's Car Genius t The 3.3L engine in your 2003 Dodge Grand Caravan does have a timing chain, not a belt. Timing chains are generally more durable than belts and can last the lifetime of the engine if properly maintained. There’s no set interval for replacing the chain, but if you hear a rattling noise or notice poor performance, it might be time to have it inspected. Just keep up with regular oil changes since a well-lubricated chain is key to its longevity!
