Timing belts are typically made from reinforced rubber, which contributes to their durability and flexibility. However, over time, exposure to heat, oil, and other engine fluids can weaken the material, leading to cracks or wear. This is why regular inspections and adherence to the manufacturer’s recommended replacement intervals are critical.

Conclusion

When you start your vehicle, the engine begins to turn. This rotation generates power that is transmitted through the fan belt. The belt itself wraps around a series of pulleys attached to different engine accessories. As the crankshaft rotates, it causes the belt to move, which in turn drives the connected components. For instance, it powers the alternator, which is responsible for generating electricity to recharge the battery and run electrical systems when the engine is on. Additionally, the fan belt helps circulate coolant through the water pump, which plays a vital role in regulating engine temperature.
