(2) pulleys.
10 Check belt deflection between the upper idler pulley and the alternator pulley using one of the following
methods.
A If Kent Moore Belt Tension Gauge is not available, belt deflection can be checked by applying moderate
downward pressure on belt. Proper deflection is approximately 1/4 in. (6 mm). Belt should not be replaced
without using this tool.
