An adjustable fan belt, typically made of durable rubber and designed for flexibility, is a key part of a car's engine system. Its main function is to connect various engine components, particularly the engine's crankshaft to the cooling system's fan. This connection allows the fan to draw air through the radiator, helping to regulate the engine's temperature. An overheating engine can lead to severe damage, making the role of the fan belt critical in maintaining an optimal operating temperature.

One of the critical factors in the performance of timing belts is their ability to resist temperature fluctuations and wear. Rubber naturally degrades over time, especially in high-temperature environments. Therefore, advancements are being made to produce timing belts that can maintain their integrity under prolonged exposure to heat. The use of heat-resistant compounds and advanced curing processes has greatly enhanced the lifespan of timing belts, reducing the risk of premature failure.
