The cambelt (timing belt) keeps the engine's pistons and valves in sync. If it snaps, the valves smash into the pistons and destroy the engine — typical scrap repair cost £2,500+. UK manufacturers specify replacement every 60,000–100,000 miles or 5–10 years, whichever comes first. Replacement cost: £350–£900 depending on engine.
The cambelt is the single most expensive part of car maintenance to skip. Here's why, and how to know when yours is due.
How do I know if my cambelt has been changed? — Service book stamp, or a sticker under the bonnet near the belt cover with the change mileage. If neither, assume it hasn't been done.
What happens if I just drive past the interval? — You're gambling. Some belts last 30,000 miles past interval, some snap on the day. There's no warning — it just goes.
