V-belts have a distinctive trapezoidal cross-section that enables them to fit snugly into the grooves of pulleys. This design allows for efficient power transfer and minimizes the risk of slipping. Typically made from durable materials such as rubber, polyester, and fiberglass, V-belts can withstand a wide range of temperatures, loads, and stretching. The layered construction of a V-belt often includes a tensile cord to enhance its strength and resistance to wear, ensuring longevity in challenging conditions.

For the Toyota Camry, it is generally recommended to replace the timing belt every 60,000 to 100,000 miles, depending on the specific model year and engine type. Always consult your owner's manual for the manufacturer’s recommendations. Some newer models are equipped with timing chains, which usually require less maintenance and are designed to last longer than timing belts. However, if your Camry has a timing belt, adhering to the replacement schedule is crucial to avoid severe engine damage.

Engine belts are rubberized components designed to transfer power from the engine to various accessories. The serpentine belt, for instance, drives multiple peripherals—such as the alternator, air conditioning compressor, power steering pump, and sometimes even the water pump. The timing belt, on the other hand, synchronizes the crankshaft and camshaft, ensuring that the engine's valves open and close at the proper times during each cylinder's intake and exhaust strokes.
