belt that goes around alternator

There are primarily two types of belts used in modern vehicles V-belts and serpentine belts. V-belts were once the standard in older car models, characterized by their V-shaped cross-section, which allows better grip on the pulleys. However, the serpentine belt has gained prominence due to its efficiency and compact design. A serpentine belt is a single, continuous belt that can drive multiple components, which reduces weight and space in the engine compartment.

Over time, the timing belt can wear out and become damaged due to heat, oil exposure, or simply the passage of time. Most manufacturers recommend inspecting the timing belt every 60,000 to 100,000 miles and replacing it as needed. Neglecting to replace a worn timing belt can lead to catastrophic engine failure. If the belt breaks while the engine is running, it can cause valves to collide with the pistons, resulting in bent valves, broken pistons, and extensive damage that can be very costly to repair.
