Serpentine vs timing belt10/3/2023 Both belts are affected by the same scenarios: overheating, oil leak, or coolant leak.Schedule Land Rover Belt Replacement Land Rover Serpentine Belt Replacement in North Bethesda A timing belt is toothed and shorter while a serpentine belt is smoother and longer.Īlso, not all cars come with a timing belt, but all cars come with a serpentine belt. Serpentine vs timing belt is quite an easy comparison. So, if you detect a leak in the engine bay, try to fix the leaking component as early as possible. Oil leaks, coolant leaks, and severe overheating are among the common reasons for serpentine and timing belt damage. Serpentine and timing belts typically last for 60,000 – 100,000 miles. Hence, it is advisable to always check on these belts. On the other hand, when the serpentine belt breaks or loosens up, everything that’s driven by the belt would stop functioning and that’s a big risk for your car’s engine. A broken/bad timing belt would force the valves to stuck open and this could lead to the damage of the valves, pistons, and/or cylinder head. If any of them fails, your engine is at great risk. Things to Note:įor vehicles that come with these two belts, it is important that both belts are functioning well. In contrast, the serpentine belt connects more pulleys and components. The timing belt connects only the camshaft and crankshaft, which must move synchronously for a car engine to run. But, if the serpentine belt looks good, check from under to see if the timing belt is the culprit. If you opened the engine bay and the first belt you saw seemed loose or broken that’s the serpentine belt and it needs to be fixed immediately. With this knowledge, you can easily tell which belt is giving you issues. On the other hand, for you to see the timing belt, you need to look deep into the engine bay or take a look from under the vehicle. It connects and powers 4 - 5 crucial components in the engine area. The serpentine belt is what you’d immediately see when you open the engine bay. With this explanation, mere looking at the belts, you would be able to tell which is serpentine and which is the timing belt. A serpentine belt looks smooth and longer, while a timing belt has “teeth” on one side and looks smooth on the other side.Īlso, a timing belt is wider than a serpentine belt but shorter in length. The first visible difference between these two belts is their appearance. That said, below are the differences between serpentine belt and timing belt: 1. Notwithstanding, both timing belts and serpentine belts use tensioners to stay tight. Some new vehicles only come with a serpentine belt. Most cars have a serpentine belt and a timing belt the two belts must be present and work fine before the car can move. Below are the differences between the timing belt and serpentine belt. The timing belt has “teeth” all around it. If the crankshaft and camshaft don’t rotate in a synchronous order, your car won’t drive.Īlso, the timing belt is a bit rough in appearance it doesn’t appear as smooth as the serpentine belt. As the name implies, the “Timing” belt synchronizes the movement/rotation of the crankshaft with the camshaft to keep your car running. Without the timing belt rotating the crankshaft and camshaft, apparently, your car won’t drive an inch. These two “shafts” connected by the timing belt are very important if your car must drive. It connects just two components - the crankshaft and the camshaft. This belt is not easily visible it is located deeper inside the engine, or even beneath the engine. Well, serpentine belts don’t fail easily, you’d notice some signs of failure whenever it starts going bad or loosens up. In other words, a bad serpentine belt would probably stop the engine from starting since connects the alternator and power steering pump. If the serpentine belt doesn’t turn, the components it connects won’t run. The serpentine belt runs continuously – from the car cracks up until you turn it off completely. The serpentine belt connects the alternator, air conditioning compressor, power steering pump, and water pump (in some vehicles). Yes, it is an important belt, and if it breaks or loosens, your engine stands at great risk. This belt is visible immediately after you open the engine bay. It is called a “serpentine” belt because it’s smooth and looks pretty much like a black “snake” curled around different pulleys/components in the engine bay.
