How often should a serpentine belt be replaced?
Serpentine belts generally last 60,000 to 100,000 miles, though newer belts can go longer. Have it inspected at each service and replace it if you see cracks, fraying, or glazing.
What happens if my serpentine belt breaks while driving?
If the belt breaks, you lose power steering, the alternator stops charging, and the water pump may quit, which can quickly overheat the engine. The car will become hard to control and should be pulled over and towed right away.
Can I replace a serpentine belt myself?
Many drivers with basic tools can do it, since the job mostly involves releasing the tensioner and routing the new belt. Just be sure to follow the correct belt-routing diagram, which is often printed under the hood.
How do I know my serpentine belt is worn?
Look for cracks, missing chunks, fraying edges, or a shiny glazed surface, and listen for squealing on startup. A worn belt should be replaced before it snaps and leaves you stranded.
Is a serpentine belt the same as a timing belt?
No, the serpentine belt runs external accessories like the alternator and AC, while the timing belt is inside the engine and syncs the crankshaft and camshaft. They are different parts with different replacement intervals and costs.
