internal timing belt

Additionally, the alternator belt aids in powering other essential components of the vehicle. For instance, the power steering pump makes steering easier by allowing fluid to flow seamlessly through the system. The air conditioning compressor relies on this belt to circulate refrigerant, providing a comfortable cabin temperature, especially during the summer months. The water pump, which is crucial for regulating the engine's temperature, also depends on the alternator belt to function correctly.

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.
