Is there a timing belt or chain in the 2002 Nissan Pathfinder?

Since 2002, the Nissan Pathfinder has featured a timing chain rather than a timing belt. Timing belts typically require replacement every 60,000-100,000 miles, but the Pathfinder's timing chain is built to last the lifetime of the vehicle without requiring maintenance. Unlike belts, metal chains are more durable and do not suffer from issues like cracking or drying out. They can also potentially enhance fuel efficiency. Chains are better shielded since they operate internally within the engine. However, if a chain breaks, it can cause severe damage to the engine. Keep an eye out for signs like metal shavings in the oil, misfires, or a rattling noise at idle, as these may indicate issues with the chain. Replacing the timing chain in the Pathfinder typically costs between $1,000-$1,100 for parts and labor.
