This is a popular question because parents are concerned about the quality of their children's education. They want to make sure that the materials they purchase will be accepted by the state, public school system or colleges.

They have a timing chain instead of a timing belt though, I've never seen or heard of a timing chain breaking on a 3.3/3.8 and causing any valve damage.sprinkles08, Chrysler/Dodge/Jeep master tech.Category: Dodge.xpert: sprinkles08 replied 4 years ago.

The engine is the same 4.0 L AMC 242 Straight-6 used in the Cherokee and Grand Cherokee. A 2.5 L AMC 150 Inline-4 motor was available on entry-level models until 2003 when the 2.4 L DOHC 4-cylinder engine previously used on the Chrysler PT Cruiser replaced it.
