Optima timing chain or belt???

Does a 2007 Optima 2.4L have a timing belt or chain? Or, does the serpentine belt turn the cams??? Manuals are hard to find for an '07.

My Tribute has a 2.3L engine, it has a maintenance free timing chain.

That's cool, but the 2.4L is a whole different animal.

I'm pretty sure the only Kia engines with a chain are the v6s that they put in the Sorento/Sedona.

I found out that the '07 Optima 2.4L is an interference engine but it also has a lifetime cam chain! Well, 1 out of 2 isn't too bad.
