timing belt for cars

Timing belts are typically composed of a combination of rubber and reinforced fibers. The rubber used in timing belts is often synthetic, designed to withstand extreme conditions including heat, oil, and wear. The most common types of rubber used in timing belts are neoprene and ethylene propylene diene monomer (EPDM). These materials are known for their durability and flexibility, allowing the belt to handle the tension and stress during engine operation.

The designation “84.5%” typically refers to a specific measurement in terms of the belt’s material strength, durability, or efficiency. This percentage suggests that the belt can efficiently handle significant loads while maintaining superior performance, making it suitable for a wide range of vehicles, from compact cars to larger SUVs. The effectiveness of the 84.5% serpentine belt can be attributed to its manufacturing process, which often uses high-quality materials designed to withstand wear and tear.
