This engine has 2 belts that must be replaced at 105,000 miles. Camshaft & Balance Shaft belts. The water pump is also driven by the cam belt and should be replaced at the same time as the belts, as this will save you labor costs later on considering the pump will need replacing before the belts need replacing at 210,000 miles.

Note: if you plan on doing this repair yourself you'll need to research how to properly align the oil pump pulley.
