Does the 2002 Nissan Pathfinder have a timing belt or chain?

Since 2002 Nissan Pathfinder is equipped with a timing chain instead of a timing belt. Most belts need replacing between 60,000-100,000 miles, but the Pathfinder's timing chain is designed to remain maintenance free and last the lifetime of the vehicle. By default, metal chains are more durable, don't suffer from cracking or drying out like belts do, and can improve fuel economy. Chains are also more protected, operating from inside rather than outside the engine. Occasionally they break, which can have catastrophic results for the engine. If You're finding metal shavings in the oil, experiencing mIS Fires or hearing a rattling noise while idling, make sure to have the chain examined by a mechanic. Cost of replacing the TC in the Pathfinder averages $1,000-$1,100 in parts and labor.
