![]() ![]() The timing belt drives the camshafts of the engine and thus, the valves. If you are due for a serpentine or timing belt replacement, we would love to assist you!

The serpentine belt drives The accessories such as the alternator, a/c compressor ect. ![]() not visible from outside.Īs you can see, both the serpentine and timing belts are important and essential to your vehicle but they are very different in appearance and purpose. The belt has horizontal teeth on the inside surface designed to fit the crankshaft and camshaft properly and it is located on the inside of the engine – i.e. It is made up of materials like neoprene, molded polyurethane or welded urethane. Has multiple V-shaped grooves that run vertically along the belt and it has a snake-like coil structure on the outside of the engine, which gives it the name Serpentine. The engine can also overheat, or you may notice physical damage to the belt. It can also cause a loss of power steering, create a lack of air conditioning or lead to a squealing noise. It is thin, black, long, ribbed and made out of rubber. The serpentine belt is not connected directly to the engine. If the serpentine belt is bad or snaps off, you may see several warning lights on the dashboard, or the car may fail to run. It allows your vehicle’s engine to operate by connecting your engine’s crankshaft to the camshaft and plays a vital role in controlling the pistons and valves in your vehicle. They are simply constructed of metal links rather than a solid and looped piece of material.It powers the alternator, power steering pump, air conditioning compressor and the water pump (in some vehicles). Timing chains serve the same purpose of synchronizing the camshaft with the crankshaft. Some vehicles have a timing chain instead of a timing belt. While all vehicles have one or more serpentine belts, they may or may not have a timing belt. With their fiberglass-reinforced construction, timing belts are inherently stronger than serpentine belts. ![]() Timing belts are still made of rubber as well, but they are reinforced with fiberglass. Serpentine belts are typically made of a rubber or a polymer-based material. Serpentine belts are designed to activate motor-driven parts and systems, whereas timing belts are used to synchronize the camshaft with the crankshaft.Īnother difference between serpentine belts and timing belts involves the material from which they are made. It is more precise than a serpentine belt in that it turns the camshaft in sync with the crankshaft, allowing the valves to open and close at the right time. It is used in older engines and is less efficient than the serpentine belt. Serpentine belt parts cost around 60 to 80, and labor costs about 50 to 70. However, the timing belt is a two-piece belt made up of teeth. Most of the time, the cost to replace the serpentine and timing belts depends on the make and model of the car. If the serpentine belt or timing belt is worn or damaged, it is best to replace it instead of trying to fix it. Differences Between Serpentine Belts and Timing BeltsĪs previously mentioned, serpentine belts and timing belts are used for different purposes. Serpentine Belt Vs Timing Belt Repair Cost. The timing belt lives up to its namesake by regulating the "timing" of the camshaft and crankshaft. As the engine runs, these parts will open and close in harmony with each other thanks to the timing belt. You can find the timing belt connected to the camshaft and crankshaft. When timed correctly, the pistons and valves will operate in harmony with each other. The timing between these two components is important for all combustion engines. Serpentine belts are oftentimes used to activate and power the following the parts:Ī timing belt, on the other hand, is a shorter piece of looped material that's used specifically to synchronize the camshaft with the crankshaft. This spinning action will then activate the parts and systems to which they are connected. While your vehicle's engine, the serpentine belts will spin. They serve completely different purposes that What Is a Serpentine Belt?Ī serpentine belt is a long and looped piece of material - they are typically made of a rubber or a similar polymer-based material - that's used to activate motor-driven parts or systems in a vehicle. While they both consist of looped pieces of material, serpentine belts and timing belts aren't the same. Most vehicles have a timing belt as well as one or more serpentine belts. When looking inside your vehicle's engine bay, you may discover several belts. ![]()
