I have a 2007 Hyundai Sonata with a 2.4l 4 cyl. engine. I know that the timing belt is not a chain. What I don’t know is if the engine is a zero clearance engine or when the timing should be changed. I have looked in the service manual and I cannot find anything that indicates when (or if) the belt should be changed. Does anyone have any ideas?
By zero clearance I assume you mean interference.
If you have nothing in the owner’s manual scheduled maintainance pertaining to scheduled changing of the timing belt, you can safely assume that you have a chain. I’ve noticed that manufacturers seem to be going back to chains. I was pleasantly surprised when I bought my Scion tC, a Camry engine, that Toyota had gone back to chains.
If you’d like to feel more comfortable, call the Hyndae service department and ask them.
If it’s a belt it WILL need to be changed. Most cars these days recommend a timing belt change every 100k miles. If it is a belt there should be a entry in the maintenance schedule of the owners manual. If it’s NOT there then call the dealer.

Yep, as of 2006 Hyundai joined the crowd & went back to using a timing chain. Thank goodness.
Congratulations! Your engine has a timing chain, and you have one less thing to worry about.
