In addition to the timing belt itself, other components of the timing system—including the tensioner and idler pulleys—should also be inspected regularly. These parts play a key role in maintaining the proper tension of the timing belt. If they wear out or fail, it can cause the timing belt to slip or misalign, leading to similar issues as a belt failure. Therefore, replacing these components simultaneously with the timing belt can save time and money in the long run.

Moreover, the fan belt drives the alternator, a critical component for generating electricity in the vehicle. The alternator charges the battery and powers electrical systems such as lights, radio, and automotive accessories. A failing fan belt can cause the alternator to underperform or completely stop working, leading to electrical failures and, eventually, a drained battery. Consequently, drivers should be vigilant about the condition of their fan belts to avoid being stranded due to electrical issues.
