How much does a timing belt replacement cost?

Car ownership is funny. You buy it brand-new, but over time, you'll have to replace some parts sooner or later to keep it running smoothly and to keep you safe. Your timing belt is no exception. It might be an oversized rubber band, but the average timing belt replacement cost is between £290+ to £730+.

Timing belts, also known as cambelts, are an integral part of an internal combustion engine, and failing to replace them regularly can significantly damage your car. Replacing a timing belt is labour-intensive and time-consuming, so it's a job best left to professional mechanics.

Timing belt replacement costs for different vehicles

Timing belt replacement costs in the UK will vary depending on the make and model of your car. Here's a table showing how much it costs to replace timing belts for various vehicles:

Differentiating timing belts and timing chains

They serve the same purpose but are made from different materials. Timing belts are made of rubber, while timing chains are made of metal. Your vehicle will only have one or the other, but not both. Timing belts and timing chains control and synchronise the rotation of your engines' crankshaft and camshaft, making your engine valves open and close at the right time. 

Like every piece of machinery, your timing belt or chain isn't immune to wear and tear. Failing to replace this might cause it to break or snap, eventually resulting in serious engine damage. Being forced to replace your car or overhauling your engine would set you back way more than it would cost you to replace your timing belt.

How long will a timing belt or cambelt last, and when should you replace it?

It depends on your vehicle manufacturer, so it's best to always refer to your owner's manual. On average, a timing belt will last 40,000 to 100,000 miles or about 7 to 10 years. 

Your timing belt should be changed within the mentioned odometer reading or timeframe. Ideally, whichever comes first. If your car uses a timing chain, it could last as long as the vehicle itself as long as you change your oil and filter regularly. 

Are there warning signs before a timing belt breaks?

Driving habits and road or weather conditions can accelerate the wear and tear on your timing belt. This might result in you needing a timing belt replacement service sooner rather than later. Here are a few signs to look out for:

1. The engine is shaking and idling roughly.

2. You can hear a rattling noise, and the engine sounds choppy.

3. The engine bay smells like burning rubber.

4. You feel the engine working harder than usual.

5. Your car won't start.

Though these indicate a faulty timing belt, it could also be a different issue altogether. Once you encounter any of them, take your car to a nearby mechanic to run a car diagnostic test and find the root of the problem.

What factors affect the cost of timing belt replacement?

Price of parts

The estimates listed above reflect timing belt service fees, excluding parts. The price of parts will directly impact the cost of replacing a timing belt. 

Emergency services

Generally, an emergency or urgent appointment will cost more than a regular one. For emergency services and mobile mechanics, the distance and time it takes for your mechanic to reach your destination, plus the hourly rate for mobile mechanical services, is factored into the costs. Weekend and holiday rates can drive up cambelt replacement costs.

Additional issues or replacement parts

Your expenses will increase if your mechanic finds additional damage or unexpected issues caused by a faulty or damaged timing belt. Timing belts almost always need replacement due to high mileage. By the time you need to replace it, other nearby components must also be changed. Most mechanics will recommend replacing your water pump alongside your timing belt. Be sure to factor the timing belt and water pump replacement costs into your budget.
