At a glance, both belts look similar, but their functions could not be more different.

The timing belt, on the other hand, is a critical internal component that keeps your engine's parts synchronized. When someone asks, "Is a timing belt the same as a drive belt?", the answer is that while a timing belt technically "drives" the engine, the term "drive belt" is most commonly used to refer to the serpentine belt.
