Yes , it must have a timing CHAIN ( the Gates website does not list a timing belt for the 2004 Nissan Xterra 2.4 liter )
The 2008 Nissan Xterra is equipped with a timing chain rather than a timing belt. Timing chains are typically more durable and require less frequent maintenance compared to timing belts. This design choice contributes to the overall reliability of the engine in the Xterra.
if it is the v6 it has a belt not chain that needs replacing every 105000 miles
Does a 2007 Nissan Sentra have a timing belt or timing chain?
...The 2005 model is the 1st of the gen-2's and therefore has a chain in the v6, previous models; considered gen-1's and had a belt...
Yes, the Nissan Xterra is classified as an interference engine. This means that if the timing belt or chain fails, the valves and pistons can collide, potentially causing significant engine damage. It's important for owners to maintain the timing components to prevent such failures. Regular inspections and timely replacements of the timing belt or chain are recommended.
