Does a 05 jaguar xj 3ltr have a cambelt?

The 2005 Jaguar XJ with a 3.0-liter engine is equipped with a timing chain, not a cambelt (timing belt). Timing chains generally require less frequent replacement than timing belts, as they are designed to last the lifetime of the engine under normal driving conditions. However, it's still important to follow the manufacturer's maintenance recommendations for overall engine health.
