A serpentine belt is another type of belt inside the engine. This belt is a V-ribbed belt that is ribbed along one side. Because of this, it bends easier and is much more flexible which allows it move and wrap around smaller accessories inside the engine.
Specifically, the ribbed side of the belt will come into contact with the grooves that are on the accessory drive pulleys and the flat side comes in contact with a tensioner roller.
The serpentine belt derives its name from its appearance and the way it is able to weave itself in and out of various accessories and pulleys with ease. A serpentine belt lasts longer than traditional drive belts and is much easier to remove and install. This belt also transmits power between the steering pump, alternator, water pump and air conditioner compressor.
A drive belt is the part inside of your engine that drives all of the accessories that are installed in the engine including the power steering pump, the alternator, the air conditioner compressor and the water pump.
The drive belt is made of extremely strong, durable rubber or rubber materials. Many newer cars may have one or two drive belts, depending on the size and function of the car. A serpentine belt can hold the engine together for several years and helps to keep important accessories of the engine system properly functioning.
However, you should ensure adequate care and attention to the belt. If you notice any sign of its failing, make sure you visit a mechanic to replace it. This will help prevent the belt from sticking in a dangerous situation.

Serpentine belts are oftentimes used to activate and power the following the parts:. A timing belt, on the other hand, is a shorter piece of looped material that's used specifically to synchronize the camshaft with the crankshaft. The timing between these two components is important for all combustion engines. When timed correctly, the pistons and valves will operate in harmony with each other. You can find the timing belt connected to the camshaft and crankshaft.
As the engine runs, these parts will open and close in harmony with each other thanks to the timing belt. The timing belt lives up to its namesake by regulating the "timing" of the camshaft and crankshaft. V belts also derive their name from the cross-section of the belt itself. In the first photo above a V belt will ride in grooves on the pulleys.
Serpentine belts don't have this same cross-section because as you can see in the 2nd photo both sides of the belt come in contact with various pulleys. It's vertical dimension is what I'll call thickness- and the serpentine belt is much thinner ie less thick than the V belt.
It's width is double or triple that of a V belt- making it more ribbon-like. It typically has 6 groves across it's width dimension and these run in complementary grooves atop the pulleys attached to the front of your motor. It's debatable but serpentine belt systems are considered superior to Vbelt driven systems. I'm sure there are plenty of cases of Vbelts dramatically outperforming serpentine belts, but in the modern car with modern engine onwards will be mfrd with serpentine belts.
