    1. ADJUST FAN AND GENERATOR V BELT
      1. Insert the adjusting bar between the engine RH mount bracket and generator. Push the bar towards the vehicle front to adjust the V-ribbed belt tension. NOTICE: Do not insert the bar between the oil control valve and generator. It could damage the oil control valve

    First tighten bolt A, then tighten bolt B on the vane pump (Power steering pump). Torque: Bolt A 19 Nm (189 kgf-cm, 14 ft. lbs.) Bolt B 54 Nm (550 kgf-cm, 40 ft. lbs.)
    1. ADJUST VANE PUMP V BELT
    1. INSPECT DRIVE BELT DEFLECTION AND TENSION
    2. INSTALL ENGINE UNDER COVER RH Torque: Bolt 5.0 Nm (51 kgf-cm, 44 in. lbs.) Nut 5.0 Nm (51 kgf-cm, 44 in. lbs.)
      1. Using the bar, adjust the V-ribbed belt tension.
      2. First tighten bolt B. then tighten bolt A. Torque: 44 Nm (449 kgf-cm, 33 ft. lbs.)

 

The refrence to an adjusting bar is a special tool. If you adjust the tension to be able to turn the belt halfway at its longest point the tension will be correct. Is the belt squeals on startup it is too loose, if you cannot turn the belt 90 degrees it is too tight
