Once the tensioner and alternator have been securely mounted, the supplied belt can be attached. The belt is most easily installed by first wrapping it around the crank, water pump, and tensioner pulley as shown in Figure 4a.

To install the belt onto the alternator, put a breaker bar with a 19mm (or 3/4”) socket on the bolt attaching the pulley to the autotensioner (see Figure 4a). In some cases, an open ended 19mm (or 3/4”) wrench may be preferred over a breaker bar. To rotate the pulley down, apply force to the breaker bar or wrench in a counter-clockwise direction.

With the pulley pivoted down, place the belt onto the alternator pulley. If the tensioner is adjusted such that belt is particularly tight, it may be necessary to install the belt onto the waterpump last, rather than the alternator.
