Here's the Pre-checks, Removal, and Installation procedure. One word of warning. A spring on the idler pulley is supposed to set the tension on the belt, but do not rely just on that. The bracket can get stuck on the pivot pin. Use a small pry bar to push the pulley to tighten the belt. That will ensure the spring is doing its job. This isn't an interference engine, so a loose belt won't hurt the valves if it jumps, but before that happens, the belt can slip over the water pump pulley resulting in the engine running too hot.
