3 Measure the belt tension in the center span of the pulleys.
An alternate method (deflection method) can be used to
check belt tension by applying 110 N (25 lbf) force between
the pulleys on v-belts. If the deflection is more than one belt
thickness per foot of pulley center distance, the belt tension
must be adjusted.
4 For cogged belts, make sure that the belt tension gauge is
positioned so that the center tensioning leg is placed directly
over the high point (hump) of a cog. Other positioning will
result in incorrect measurement.

To make sure the cooling fan drive belt is routed correctly upon
installation, make a diagram of the cooling fan belt routing prior to
removing the belt as shown in the illustration.
