Alternator and Fan Belts - Inspect/Adjust
To maximize the engine performance, inspect the belt for wear and for cracking. Replace a belt that is worn or damaged.
If a belt is too loose, vibration causes unnecessary wear on the belt and pulleys. Loose belts may slip enough to cause overheating.
To accurately check the belt tension, a suitable gauge should be used.

- Loosen bolts (1) and adjusting bolt (2). Loosen bolt (4).
- Move the alternator (3) in order to increase or decrease the belt tension.
- Tighten adjusting bolt (2). Tighten bolts (1) and tighten bolt (4). Refer to the Specifications Manual for the correct torque settings.
