Depends on what year it is and which engine it has. If it has a pushrod engine in it, it has a timing chain instead of a belt. If it is an overhead cam engine, then it does. Keep in mind that the Malibu was originally a Chevelle model starting in 1964. The Malibu replaced the Chevelle in 1978, so there are a lot of possibilities here.
