2. Brand Reputation Well-established automotive brands often command higher prices due to their reputation for quality and reliability. Manufacturers such as Gates, Dayco, and Continental have built trust over decades, and their products typically reflect advanced engineering and testing processes. While opting for a lesser-known brand might save money upfront, it could result in quicker wear and the need for additional replacements, ultimately costing more in the long run.

The mechanism for varying the pulley diameter can take many forms, including adjustable sheaves or conical pulleys. By changing the effective diameter of the pulleys, the system can alter the speed ratio between the input and output. As the diameter of the driving pulley decreases, the speed of the driven pulley increases, and vice versa. This principle allows for smooth transitions in speed and ensures that the system can operate efficiently under varying loads.

Despite their durability, PK belts can wear out, fray, or crack over time due to heat, tension, and environmental factors. A worn belt can lead to slippage, which may cause inadequate power transfer to the alternator and other accessories, leading to electrical failures or battery drain. Consequently, it is vital to inspect the PK belt regularly and replace it when signs of wear become evident, typically every 60,000 to 100,000 miles, depending on the vehicle and driving conditions.
