When Does a 2008 jeep Cherokee 2.8 diesel have a timing belt or chain?

The 2008 Jeep Cherokee with a 2.8-liter diesel engine is equipped with a timing chain rather than a timing belt. Timing chains are generally designed to last the life of the engine and typically require less frequent replacement than timing belts. However, it's always a good idea to consult the owner's manual or a professional mechanic for specific maintenance recommendations.
