Serpentine Belt: what it does & when to replace it
The serpentine belt is a single belt that drives accessories like the alternator, water pump, power-steering pump, and A/C compressor. A worn belt causes squealing (especially on cold starts), and a snapped belt can cause overheating and loss of charging and power steering at once. Inspect for cracks, glazing, or fraying; most belts last 80,000–160,000 km. Replacement is a moderate DIY job — the trickiest part is releasing the spring-loaded tensioner and routing the belt correctly, so photograph the routing diagram first.
DIY difficulty: Moderate DIY (note the belt routing first). Always confirm the correct part for your exact build by VIN before buying.
