Timing belt replacement cost

By Fakhri · Last reviewed

Quick answer

Replacing a timing belt usually costs about $250 to $1,250 in the US, or about £300 to £800 in the UK, with most UK jobs averaging a little over £400. It is mostly labor. The belt has to be changed at the interval in your owner's manual, because on many engines a snapped belt wrecks the engine.

Timing belt or timing chain?

The timing belt (called a cambelt in the UK) keeps the crankshaft and camshafts turning in step, so the valves open at exactly the right moment. Some engines use a metal timing chain instead.

  • Belt. Made of reinforced rubber. It wears with age and mileage and must be replaced at a set interval. It can break without warning.
  • Chain. Lasts much longer and normally has no replacement interval unless there is a problem. Regular oil changes help prevent wear and stretching. A worn chain often rattles before it fails: get that checked promptly.

If your car has a chain, you do not need this job as routine maintenance.

How often to replace a timing belt

There is no single interval: it depends on the engine, so follow your owner's manual or service schedule. Most manufacturers say somewhere between 60,000–105,000 miles100,000–170,000 km, and some as early as 40,000 miles65,000 km. There is usually an age limit too, often 5 to 10 years, whichever comes first. A car that does few miles still needs its belt changed on time, because rubber ages.

Why skipping it can cost you the engine

On an interference engine, the valves and pistons share the same space at different moments. If the belt snaps, they collide. Bent valves and damaged pistons can turn a few-hundred-dollar service into a major rebuild or a replacement engine. On a non-interference engine, a snapped belt usually just stops the engine. Interference designs are common because they help power and fuel economy; your garage can tell you which type you have.

If the belt fails while you are driving, you lose engine power and power assistance for steering and brakes. Steer to the side of the road, stop safely and do not try to restart the engine.

What pushes the price up or down

  • Your car. In AutoPadre's examples, a 2004 Ford Focus was about $246 and a 2008 Audi A4 about $1,085. In UK FixMyCar data, a Kia averaged about £385 and a BMW about £540 for belt and water pump.
  • Engine layout. Labor is most of the bill, and some engines take far longer to strip down than others.
  • What else is replaced. The tensioner and the water pump are often changed at the same time, which adds parts cost but saves labor later.
  • Where you go. Dealers charge more per hour than independent garages.

How to avoid overpaying

  1. Check your service history. If it was done recently, you may not need it yet. Keep the invoice when you do: buyers ask for it.
  2. Do the water pump at the same time if the belt drives it. Replacing the pump on its own later means paying most of the labor again.
  3. Ask what the kit includes: belt, tensioner, idlers, water pump, coolant.
  4. Get two or three quotes for your exact car and engine.

Questions drivers ask

Does my car have a timing belt or a timing chain?

Your owner's manual or service schedule will say: if it lists a timing belt or cambelt replacement interval, you have a belt. A chain is metal, runs in engine oil and usually has no set replacement interval. A garage can also tell you from the registration or VIN.

What happens if a timing belt snaps?

The engine stops immediately. On a non-interference engine it usually just stalls and needs a new belt. On an interference engine, the pistons and valves can hit each other, bending valves or damaging pistons. That can mean a major rebuild or a replacement engine.

Should I replace the water pump at the same time?

Usually, yes, if the belt drives the pump. The pump sits behind the belt, so most of the labor is already paid for. In the US that typically adds about $100 to $200 for the pump and tensioner.

Are there warning signs before a timing belt breaks?

Often there are none. That is why you replace it by mileage or age, whichever comes first, rather than waiting for symptoms.

I bought a used car with no record of the belt being changed. What now?

If the car is at or near its interval, or you cannot prove it was done, treat it as due and have it replaced. It is far cheaper than an engine.
