Does the Nissan Sentra have a timing belt or chain?

Any Nissan Sentra that is made in the last thirty years or so is going to come with a timing chain. I don't think Nissan has put a timing belt in the Sentra since the last 1980's. Since You are likely to have a chain that means that You're not going to have to deal with the maintenance that You would have with a timing belt. It's common for it to last for as long as Your engine does as opposed to belts that dry out and break at a certain point. While the chain is a bit more expensive to manufacture and repair, it has the benefit of being a long lasting part that shouldn't wear down on You for many years. -
