When Is It Needed?
Timing belt replacement intervals vary by manufacturer, typically every 40,000–100,000 miles or 4–5 years. Check your service book — this is one repair where the manufacturer's schedule should be followed precisely. Some engines use timing chains instead, which generally last the life of the engine.
Labour Time
A timing belt replacement is a major job, typically taking 3–5 hours depending on the engine. Transverse-mounted engines (front-wheel drive) are usually quicker. Some V6 and V8 engines can take 6–8 hours due to limited access.
Warning Signs
- •You've reached or exceeded the manufacturer's recommended replacement interval
- •Ticking or clicking noise from the engine at idle
- •Engine misfires or runs rough
- •Oil leaking from the front of the engine near the timing cover
- •The engine occasionally won't start or cranks longer than usual
What's Involved in the Repair?
- 1
The engine is brought to top dead centre (TDC) and timing marks are aligned
- 2
The front of the engine is partially disassembled — removing covers, pulleys, and the auxiliary belt
- 3
The old timing belt and tensioner are removed
- 4
The new belt, tensioner, and idler pulleys are fitted and tension set to specification
- 5
The water pump is often replaced at the same time as it sits behind the timing belt
- 6
Everything is reassembled and the engine timing is verified
Expert Tip
Always replace the water pump, tensioner, and idler pulleys at the same time — the extra parts cost is minimal compared to the labour savings. A failing tensioner can destroy a brand new belt.
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.
