Frequently Asked Questions
- How do I replace the serpentine belt on a Ford Fiesta?
- Release tension on the automatic tensioner with a breaker bar, slide the old belt off, route the new belt per the diagram (usually on a sticker under the hood), and release the tensioner onto the new belt. The job takes 15-30 minutes.
- How do I know if my Ford Fiesta serpentine belt needs replacing?
- Signs include squealing at startup, visible cracks or fraying on the belt, loss of power steering or A/C, and the battery light coming on. Most belts should be replaced every 60,000-100,000 miles.
- What happens if the serpentine belt breaks on my Ford Fiesta?
- If the serpentine belt breaks, you lose power steering, alternator charging, A/C, and (on some engines) the water pump. Pull over immediately — driving without the water pump will cause overheating and engine damage.
- Where is the belt routing diagram on a Ford Fiesta?
- Most Ford Fiesta models have a belt routing diagram on a sticker under the hood, near the radiator support or on the inner fender. If it's missing, check the service manual or see the diagrams below.
