Does the 2006 Hyundai Tucson have a timing belt or chain?

The 2006 Hyundai Tucson uses a timing belt under the hood in both the 2.0L and the 2.7L engine variants. It's recommended that You change the timing belt on this vehicle every 60,000 to 80,000 miles, to account for routine wear and tear. The replacement will typically cost You around $400 -- while it sounds like a lot for preventative maintenance, the alternative is failure, sometimes catastrophic. Most folks prefer timing chains because of their estimated lifetime of 250,000 miles. However, if they fail, You're likely looking at a repair cost that can nearly 10x the timing belt's $400 estimate. While You may feel You're getting nickel and dimed at regular intervals, the alternative is gambling on failure. Stay on top of the maintenance, and You should do just fine.
