There are three types of drive belts:

A serpentine belt is located under the hood of a car, and it “snakes” its way between various pulleys and accessories. This type of drive belt is usually found in cars produced after 1990. It also tends to last longer than other types of drive belts, is simple to install and remove, and transmits power between a car’s air conditioner compressor, water pump, alternator, and steering pump.

A V-belt runs off a crank and pulley and typically travels between one or two engine accessories. Older cars often have several V-belts used for power steering, air conditioning, and other operating essentials. V-belts can be more difficult to change than serpentine belts. Additionally, if V-belts become loose, they can cause your alternator to malfunction and lead your engine to overheat.

A timing belt links your car engine’s crankshaft to its camshaft; the crankshaft helps the engine’s pistons rotate, while the camshaft helps open and close engine valves. It can be tough to see the timing belt due to the fact that it is likely hidden underneath a timing cover. However, the timing belt should not be ignored; otherwise, if the timing belt wears down and malfunctions, it may result in a costly, time-intensive engine rebuild.
