YM25133-004900 Komatsu FAN BELT

This belt basically connects the engine’s crankshaft to things like the alternator, the power steering pump, and sometimes the air conditioning compressor, and of course, the fan itself. It’s a simple loop of reinforced rubber that transfers rotational power from the engine to run those accessories. Different engines might have one long belt running everything, or a few separate belts for each component. Think of it as the engine's workhorse for powering things other than the wheels. Everything that needs to run while the engine is running, and isn't directly related to moving the car, gets its power from this belt. It’s constantly spinning, so it's under a lot of stress. Honestly, it’s hugely important. If this belt breaks, you’ll immediately notice. Your battery light will come on because the alternator won't be charging it. Your power steering will get really hard, maybe impossible. Your AC will stop working. And, depending on the vehicle, the engine could overheat pretty quickly if the fan isn't running. It acts like a shield protecting those important components from failing. It’s a relatively inexpensive part compared to the damage a broken one can cause. We carry a good selection here and you can always find options at Fixparts Online if you prefer to look yourself. Replacing it before it fails is always the smart move. They do wear out over time, so it's a regular maintenance item. Next-gen performance: Fan Belt (MPN YM25133-004900) is backed by a 12-month warranty!
