3. Align a straight edge over the drive belt and across the
pulleys as shown in
Figure 106
4. Press the belt down at the midway point between the
fan pulley and the alternator pulley as shown in
106.
Note: The range of belt deflection between the
straight edge and the belt should be 7 to 9 mm (0.28 to
0.35 inches), under a load of 10 kg (22 lb).
5. If the tension of the belt is above or below the specified
range, adjust the drive belt tension; refer to
