This belt’s job is to connect the crankshaft to things like your water pump, alternator, and sometimes even the power steering pump. It’s got these teeth on it—that’s where the name comes from—that mesh with pulleys on those components, basically transferring the engine’s rotational force to make them work. It's not like a traditional V – belt, which relies on friction; this one has a positive grip. Think of it as a critical link in keeping everything running smoothly. The crankshaft spins as your engine runs, and this belt takes that power and distributes it. Without it, your battery won't charge (no alternator working), your engine could overheat (water pump stops), and you’ll lose power steering. It’s a pretty important component. Honestly, it’s a wear item. Rubber degrades over time, gets brittle, and eventually can snap. If it does, you’ll notice if you’re lucky because things will suddenly stop working, and you’ll probably hear some noise beforehand like a squealing sound. But if it breaks completely without warning, it can cause a lot of damage. It’s much cheaper to replace it as part of regular maintenance than to deal with the consequences of a broken one. We often recommend replacing it around 60,000 to 90,000 miles, depending on the vehicle. You can find a good selection of these at places like Fixparts Online, and they'll often have the right one for your specific make and model. It really acts like a shield preventing more serious and expensive failures. Versatile and reliable: Toothed Belt (MPN 1987949107) includes a 12-month warranty!
