15194757 Volvo Construction IDLER PULLEY

This pulley doesn’t actually drive anything. It's a smooth wheel that the serpentine belt wraps around. Its main job is to guide the belt and maintain the right amount of tension on it as it goes around all the other pulleys – things like the alternator, power steering pump, and AC compressor. It essentially changes the belt’s direction of travel. Think of it as a helper. All those driven accessories need the belt to run, and the idler pulley makes sure the belt stays properly aligned and doesn't rub or fray on its way around. It keeps everything running smoothly. It’s positioned somewhere along the belt’s path, and each engine design has a specific place for it. A failing idler pulley can cause a lot of trouble. If it gets worn, the bearing inside can go bad. You’ll notice if that happens – probably with a whining or squealing noise, especially when you first start the car or when you put a load on the engine, like turning on the AC. If it fails completely, the belt can jump off the pulleys, and that can leave you stranded. It can also damage the belt and other components. It acts like a shield, protecting the rest of the belt drive system. A new one is relatively inexpensive, and you can find them easily at places like Fixparts Online, so it’s a good idea to replace it if it’s making noise or feels rough when you spin it by hand. Ignoring it can lead to much bigger, more expensive problems down the road. Get more for your money: Idler Pulley (MPN VOE15194757) is covered for 12 months!
