Do not confuse - the serpentine belt is different from the synchronous belt. Serpentine belts and synchronous belts have very different functions in your vehicle.
The timing belt is located inside the engine to keep the crankshaft and camshaft synchronized. This can ensure that the intake and exhaust valves and pistons of the engine are opened and closed in time, so that the engine can run smoothly.
The serpentine belt keeps the engine accessories running smoothly and efficiently. It connects the engine crankshaft outside the engine to all engine accessories.
When you look at the grooves, you can easily distinguish between the two. The timing belt has horizontal "teeth" designed to mount the gears of the crankshaft and camshaft. The serpentine belt has a plurality of V-shaped grooves that extend vertically along the belt. These belts usually need to be replaced at the same time,
When should the serpentine belt be replaced?
The serpentine belt is durable. Ideally, your vehicle's serpentine belt should be capable of running 60000-100000 miles.
As part of the regular maintenance of the vehicle (even if it looks ok), it is important to replace this belt to avoid it breaking on the road.
