Does the 2009 Hyundai Elantra have a timing belt or chain?

The 2009 Hyundai Elantra's 2.0L 4Cylinder engine uses a timing belt, which the manufacturer recommends changing every 90,000 miles. This is due to routine wear and tear, which You're going to want to get out ahead of -- catastrophic failure while You're driving can potentially lead to the destruction of the car (and even loss of life). Contrast this with a timing chain, which is good for an estimated 250,000 to 300,000 miles. The bad thing about chains, though, is that when they fail, they're much more expensive to replace. It might seem like You got the short end of the stick with a belt, but as long as You keep up with its regular maintenance, You shouldn't have any problems.
