12/13/2023 0 Comments Serpentine vs timing beltUsing just one belt to run all the accessories is cost-saving and efficient. This belt winds through all the pulleys of these accessories to receive and transmit power from the original power source, which typically originates in the alternator. Most modern cars typically use just one accessory or a serpentine belt. This is the reason why this belt is also called an accessory belt or fan belt. These components are called engine accessories. It is called a serpentine belt because it twists, turns, and coils around to accommodate all the pulleys that it is connected to. It should have this kind of length because it has to be connected to at least seven pulleys of different diameters. The serpentine belt is long and is made of reinforced rubber. Timing belts have horizontal grooves that are designed to fit the cogs or teeth of the crankshaft. They run vertically along the inside diameter of the belt. The grooves of the serpentine belt are V-shaped. Timing belt – how do they compare in terms of grooves? Thus, it can maintain the right synchronization between the crankshaft and the camshaft. This design prevents the pulley from slipping under the belt. The cogs of this belt should match the cogs or teeth on the pulley it is connected to. It is a cogged belt – meaning it has teeth on its inside parts. That means this belt is directly connected to the pulley of the crankshaft, which turns the camshaft. In contrast, the timing belt is a direct drive. Its role is to drive or turn or rotate all the pulleys that are connected to it. The force that it generates depends on the friction between the belt and the pulleys’ surfaces it is turning. The serpentine belt is friction drive or friction oriented. Serpentine – which one is friction and drive oriented? Serpentine Belt Serpentine Belt Is Friction Drive While the Timing Belt Is Direct Drive Your repair costs could run into hundreds of dollars to remove the broken belt and replace it with a new one. While this belt is inexpensive and easily available, the work of replacing it is challenging. If they continue turning, the pistons inside the cylinders could hit any open valve and damage the engine. Most engines are designed so that the crankshaft and camshaft will not continue turning if this belt snaps. This belt is encased in a steel casing and is very difficult to replace. Its role is to turn the crankshaft and the camshaft so that the engine valves inside the engine can open and close. On the other hand, the timing belt is directly connected to the engine through the crankshaft rod. However, without the power accessories doing their individual work, the engine might overheat, the inside of the car will get hot, and you will not be able to travel very far.įortunately, a serpentine belt is inexpensive and easy to replace. If this belt snaps, you will still be able to drive your car – but only for a short distance. These accessories include the alternator, the power steering pump, the water pump, and the air conditioner. It is connected to the power accessories that are not inherent parts of the engine. The serpentine belt is external to the car engine. Connection to the Engine Is Different Serpentine Belt Below are3 key differences between a timing belt vs. There are several differences between the serpentine belt and the timing belt. The timing belt is connected directly to the engine and is driven by the crankshaft, which turns the camshaft. It runs the power accessories attached to the engine. The serpentine belt is not connected directly to the engine. Read on to learn more about the contrast between the serpentine belt and the timing belt as well as their roles in the efficient performance of your car. The belt runs the power accessories attached to the engine, such as the alternator, power steering pump, water pump, and air conditioner. It makes the crankshaft and camshaft agree with each other and opens and closes the engine valves. The serpentine belt is located outside the engine. The timing belt is found inside the engine casing. The function of the serpentine belt is very different from the function of the timing belt. You may have heard of a timing belt, but do you know what a serpentine belt is? What is the difference between a serpentine belt vs.
