Frequently Asked Questions
When should a timing belt be replaced?
Most manufacturers recommend replacement every 40,000–100,000 miles or every 4–5 years, whichever comes first. Check your vehicle's service schedule — a snapped timing belt can destroy an interference engine, costing thousands.
What happens if my timing belt snaps?
In an interference engine (most modern cars), a snapped belt allows pistons to hit the valves, causing catastrophic internal damage. Repair costs can exceed £2,000–£4,000, far more than preventative belt replacement.
Should I replace the water pump with the timing belt?
Yes — it's strongly recommended. The water pump is accessed during the timing belt job, so the additional labour cost is minimal. A failing water pump can contaminate or damage the new belt.
