Belts - Inspect/Adjust/Replace
Inspect the alternator belt and the fan drive belts for wear and for cracking. Replace the belts if the belts are not in good condition.
Check the belt tension according to the information in the Service Manual, "Specifications".
Slippage of loose belts can reduce the efficiency of the driven components. Vibration of loose belts can cause unnecessary wear on the following components:
- Belts
- Pulleys
- Bearings
If the belts are too tight, unnecessary stress is placed on the components. This reduces the service life of the components.
