Timing Belts and Chains

How do change the drive belt on 2003 Subaru Outback LL Bean with a 3.0 H6 engine?

By drive belt; I assume you mean a timing belt. On a 3.0 H-6, there is a timing chain in place of the belt (Very durable). It is housed behind cast aluminum timing chain covers on the front of the engine. On an engine with a timing belt, I would do the change myself; but I recommend that a timing chain be replaced by a Subaru dealer simply for the fact that the tension, alignment, and timing can be hard to set yourself with a chain.
