YM25137-003400 Komatsu V-BELT

This belt’s job is pretty straightforward – it transfers power from the engine’s crankshaft to various components like the alternator, power steering pump, the air conditioning compressor, and sometimes even the water pump. It’s a simple system relying on friction, basically a rubber loop connecting everything. Think of it as the engine’s messenger. The engine makes the power, and the V – belt delivers it where it needs to go to keep everything running smoothly. It wraps around pulleys on each of those components, and as the engine spins, the belt turns those pulleys, powering those systems. It’s a key part of the “serpentine” system in a lot of newer cars, but even older vehicles use variations of this. A failing V – belt can cause a whole lot of trouble. Because it’s powering things like your charging system (the alternator), if it breaks while you're driving, your battery won't recharge and you'll eventually lose power. It also means your power steering gets hard, your AC stops working, and in some cases, your engine can overheat if the water pump isn't turning. It acts like a shield, preventing those systems from just stopping. You’ll notice if it’s going bad – you might hear a squealing sound, especially when you first start the car or when you put a load on those systems like turning the steering wheel. Sometimes you'll also see cracks or glazing on the belt itself. You can find replacements pretty easily, and a site like Fixparts Online has a good selection. It's a relatively inexpensive part, but getting it replaced before it fails can save you a lot of headaches and potentially expensive repairs down the road. Highly recommended: V-Belt (MPN YM25137-003400) comes with a 12-month warranty!
