How Much Does It Cost to Replace a Cambelt?
A cambelt (also known as a timing belt) is one of the most essential parts inside your car’s engine. It keeps your engine’s crankshaft and camshaft turning in sync, making sure the valves and pistons move at just the right time. If your cambelt fails, the results can be disastrous and very expensive. That’s why many drivers ask, “How much does it cost to replace a cambelt?” This blog covers everything you need to know about cambelt replacement costs, including the factors that affect the price, why regular replacement is vital, and how to save money without compromising your engine’s health.

What Is a Cambelt, and Why Is It So Important?
A cambelt is a rubber belt with teeth on the inside. Its main job is to control the timing of your engine’s valves and pistons. If the cambelt wears out, slips, or breaks, the engine parts inside can collide, causing severe damage.
Signs your cambelt may need replacing:
- Ticking or rattling noise from the engine
- The engine misfires or has trouble starting
- Oil is leaking from the front of the motor
- The engine fails to turn over
Ignoring a cambelt replacement can lead to very costly repairs, sometimes even a complete engine replacement.
When Should You Replace a Cambelt?
The frequency of cambelt replacement depends on your car’s make, model, and age. Most manufacturers recommend changing the cambelt every 40,000 to 100,000 miles or every 4 to 6 years—whichever comes first. Always refer to your owner’s manual for the proper maintenance schedule.
If you’re unsure, ask a mechanic to check the belt’s condition at your next service.
What Affects Cambelt Replacement Cost?
1. Car Make and Model:
Luxury or performance cars often have more complex engines. Cambelt replacements in vehicles such as Audi, BMW, or Mercedes tend to be more expensive than budget models like Ford or Vauxhall.
2. Labour Time:
Replacing a cambelt can take anywhere from 2 to 6 hours. Cars with easy engine access have lower labour costs. In contrast, vehicles where the belt is hard to reach require more time and expertise.
3. Location:
Garage rates vary by region. Cambelt replacement costs are often higher in urban areas than in rural areas.
4. Replacing Other Parts:
Mechanics often replace the water pump, tensioners, and pulleys simultaneously, as they wear out together and are difficult to access separately. Bundling these jobs increases the upfront cost, but saves you money in the long run.
5. Type of Garage:
Main dealer garages generally charge more for parts and labour than independent garages. Mobile mechanics often offer more competitive rates, but be sure they are reputable and reliable.
Average Cambelt Replacement Cost in the UK
For most standard vehicles:
You can expect to pay between £300 and £800 for a cambelt replacement by a reputable independent garage. For luxury or high-performance models, costs can rise to £600–£1,200, especially if additional parts or extensive labour are required.
Typical breakdown:
- Labour: £200–£400
- Cambelt kit: £50–£200
- Water pump (if changed): £50–£180
- Fluids, seals, and extras: £20–£50
Total on average: £350–£700
Dealerships may charge even more, often £500–£ 1,000 or more, for the same work.
Why Replace the Water Pump with the Camshaft?
The camshaft drives most water pumps. If one fails, it can cause the other to fail as well. It makes sense to replace both together to save on duplicate labour costs and reduce the risk of breakdowns. It’s a smart preventive step—even if it adds another £50–£180 to the price.
Risks of Skipping or Delaying Cambelt Replacement
- Complete engine failure: In interference engines, a broken camshaft allows pistons and valves to smash together.
- Expensive repairs: Valve damage, ruined cylinder heads, or even full engine replacement may result, costing thousands.
- Sudden breakdown: A Cambelt failure can leave you stranded anywhere, anytime, with no warning.
Replacing your cambelt on schedule is much cheaper than repairing an engine after a belt failure.
How to Get the Best Price on a Cambelt Replacement
1. Compare Quotes:
Always obtain quotes from several local garages, including dealerships and independents. Ensure you’re comparing like-for-like (does the quote include the water pump, tensioner, and VAT?).
2. Check What’s Included:
Is it just the cam belt, or a complete cam belt kit with tensioners and pulleys? Are new seals, fluids, and the water pump included?
3. Ask About Warranties:
Good garages will guarantee parts and labour for 12 months or more. This protects you if any parts fail after replacement.
4. Bundle Services:
If you’re due for a major service, MOT, or need the water pump checked, ask for a package deal. Working together on jobs saves on labour costs.
5. Choose Trusted Mechanics:
Don’t settle for the cheapest quote if it sacrifices quality. Cambelt replacement is complex, and a mistake can destroy your engine. Check reviews and ensure the mechanic has experience with your car’s make and model.
Dealer vs Independent Garage: Which Should You Choose?
Dealership Pros:
- Use OEM (original equipment) parts
- Dealership service history for warranty claims
- Factory-trained mechanics
Dealership Cons:
- Highest labour rates
- Less likely to negotiate
- Sometimes booked up for weeks
Independent Garage Pros:
- Competitive prices
- Can use OEM or high-quality aftermarket parts
- Flexible appointments
- Often, more personal service
Independent Garage Cons:
- Always ensure they have the right experience and tools for your vehicle
For many drivers, a reputable independent garage like Gforce Tyres offers the best balance of price, skill, and flexibility.
Cambelt vs Timing Chain: What’s the Difference?
Some engines use a timing chain instead of a cambelt. Timing chains are made of metal and are designed to last the lifetime of the car, but they can still fail and require costly repairs. Always check your owner’s manual to confirm whether your vehicle has a cam belt or a timing chain.
Signs Your Cambelt Needs Changing Soon
- High mileage or old age (near the manufacturer’s recommended interval)
- Visible cracks, wear, or missing teeth on the belt
- Unusual engine noises, especially ticking or rattling
- Difficulty starting or engine misfires
- Past due on scheduled replacement—don’t delay!
It’s best to replace early rather than risk expensive damage.
Cambelt Replacement: Step-by-Step Process
- Preparation: Remove the engine covers, drain any required fluids, and ensure all necessary parts are accessible.
- Tension Release: Remove the accessory belts and release the tension on the old cam belt.
- Belt Removal: Remove the old cambelt, being careful not to disturb the timing marks.
- Component Inspection: Check pulleys, tensioners, and the water pump for wear; replace as needed.
- Install New Belt: Fit the new belt and adjust it to the correct tension.
- Reassembly: Reinstall components, refill fluids, and check all connections.
- Test: Start the engine and confirm smooth operation, listening for any unusual noises.
This is not a DIY job for most car owners. Cambelt fitting requires special tools, timing knowledge, and great care.
Can I Replace a Cambelt Myself?
Cambelt replacement is one of the riskiest DIY jobs for a car. If you set the timing incorrectly by even one tooth, the engine may not run, or worse, it may suffer significant internal damage. Unless you have solid mechanical experience and the right tools, it’s best to leave this job to the professionals. At Gforce Tyres, our expert team can replace your cambelt safely and correctly, so you don’t have to worry.

Frequently Asked Questions
Does my car have a timing belt or a timing chain?
Check your owner’s handbook or ask a mechanic. Not all engines are the same.
Should I also replace the water pump, tensioners, and pulleys?
Yes, most experts recommend it. These parts are difficult to access once the cam belt is fitted, and if they fail, they can damage your new belt.
How long does a cambelt replacement take?
Usually 2–6 hours, depending on your vehicle.
Does the warranty cover camshaft failure?
Not if you miss scheduled changes, so always stay up to date with your car’s service plan.

Cambelt replacement isn’t cheap, but it’s much less expensive than engine repair after a failure. Expect to budget £300–£800 for most cars in the UK, higher for luxury or performance models. Always obtain several quotes, verify the complete kit replacement, and select a skilled, experienced mechanic.
Don’t gamble with your engine. Sticking to your maintenance schedule for cambelt replacement is the smart, safe, and cost-effective way to keep your car running for years to come.
