Instructions for Replacing Auxiliary Belt

Model: Toyota Avensis MK 1, T220 - Years 1997-2003
Part: V-belt

The auxiliary belt, which also drives the alternator, is tensioned by the adjustment system located under the alternator. To replace the belt, you need to loosen the upper mounting bolt of the alternator, then loosen the lower bolt that acts as a tensioner, allowing the alternator to move up and down to loosen and tighten the belt. Once the tensioner is loosened, you can remove the old belt and fit the new one (ensure compatibility by comparing the number of grooves and length), tension it using the appropriate adjuster, and then tighten the upper bolt of the alternator.
