Examination
1. Check the belt tension as follows:
Using the MUT-II device
Warning: Before connecting or disconnecting the MUT-II, turn off the ignition. For detailed information on measuring vibration frequency using the MUT-II, see the chapter "Checking and adjusting the tension of the generator drive belt".
Using your hand, gently press the belt between the pulleys at the location indicated by the arrow in Figure 2.5 and check that the belt oscillation frequency matches the nominal value.

Without using the MUT-II device
Using a special tool for measuring belt tension, check that the tension corresponds to the nominal value (Fig. 2.5)

By belt deflection
1. Apply a force of approximately 98 N to the center of the belt branch between the pulleys at the location indicated by the arrow in Figure 2.5 and check that the deflection matches the nominal value.
Power steering pump and air conditioning compressor drive belt tension:
- when checking:
- oscillation frequency: 114-139 Hz
- tension: 392-588 N
- deflection: 10.0-12.0 mm
- when installing a previously used belt:
- oscillation frequency: 121-133 Hz
- tension: 441-539 N
- deflection: 10.0-11.0 mm
- when installing a new belt:
- oscillation frequency: 145-166 Hz
- tension: 637-833 N
- deflection: 7.0-9.0 mm
2. If the measured belt tension and deflection values differ from the standard values, adjust as follows.
(1) Loosen tensioner pulley mounting bolt A.
(2) Turn adjusting bolt B to adjust the belt tension.
(3) Tighten tensioner pulley mounting bolt A.
Tightening torque: 25 Nm.
(4) Check the belt deflection and, if necessary, readjust the tension.
Warning: The check is carried out after turning the crankshaft one revolution clockwise.
