Quick answer: A timing belt replacement typically costs $500–$1,000 for a 4-cylinder engine and $700–$1,500+ for a V6, usually including a new water pump, tensioner and idler pulleys. Most manufacturers recommend replacement every 60,000–105,000 miles or 7–10 years, whichever comes first.
Timing belt replacement cost breakdown
Estimates updated October 2026, independent shop prices with labor at $100–$200 per hour.
| Engine type | Labor hours | Belt kit with water pump | Typical total (independent) | Dealer |
|---|---|---|---|---|
| 4-cylinder (e.g. Honda Civic/Accord, Hyundai, older Toyota) | 3 – 5 | $150 – $350 | $500 – $1,000 | $800 – $1,400 |
| V6, transverse (e.g. Honda Odyssey/Pilot, Acura, Toyota 1MZ) | 4 – 7 | $250 – $500 | $700 – $1,500 | $1,100 – $2,000 |
| Interference engines with extra parts (cam seals, hydraulic tensioner) | 5 – 8 | $300 – $600 | $900 – $1,800 | $1,300 – $2,300 |
Why replace the water pump at the same time?
On many engines the timing belt drives the water pump, so the pump is behind the same covers. Replacing it during the belt job adds only $50–$200 in parts and little labor. If the old pump fails later, you’d pay most of the labor again. The same logic applies to the tensioner, idler pulleys and camshaft/crankshaft seals.
When to replace a timing belt
- Follow the interval in your owner’s manual: commonly 60,000, 90,000 or 105,000 miles.
- Also replace it by age (often 7–10 years) even if mileage is low; rubber ages.
- Replace it sooner if it’s oil-soaked from a leak or shows cracks.
- Buying a used car? If there’s no proof of a belt change at the right mileage, budget for it.
What happens if the timing belt breaks
On an interference engine, the valves and pistons can collide when the belt breaks, causing major damage: $2,000–$5,000+ or a replacement engine. On a non-interference engine, the car simply stops and you’ll need a tow and a new belt. Either way, it usually happens without warning.
Timing belt vs timing chain
Many newer engines use a timing chain, designed to last the life of the engine with no scheduled replacement (for example, the Toyota Camry engines covered in Toyota Camry Water Pump Replacement Cost). Check your owner’s manual or ask a shop which one your engine has.
Signs of a worn timing belt
- Ticking noise from the engine front.
- Engine misfires or rough running (the belt may have jumped a tooth).
- Oil leaking from the front of the engine.
- Visible cracks or missing teeth (if you can see the belt).
How to save money
- Use an independent shop that knows your brand.
- Buy a complete kit from a reputable brand (Aisin, Gates, Continental) rather than cheap belt-only kits.
- Do other front-of-engine work (drive belts, seals) at the same visit.
