What is a Serpentine Belt?

A serpentine belt is a critical component in your Toyota’s engine that plays a key role in powering essential systems.

  • Essential for functionality: Without it, key systems in your vehicle would not operate.

Maintaining your serpentine belt is crucial to avoid unexpected breakdowns and costly repairs, underscoring the importance of understanding its lifespan.
