The timing belt Timing belt replacement is one of the most critical parts of your car. If it breaks while driving, it can lead to serious engine damage with repair costs of up to €8,000. Yet, timing belt replacement is often postponed, with all the consequences. This comprehensive guide explains when to replace your timing belt, the intervals for each car brand, and how to prevent costly damage.
What is a Timing Belt and What Does It Do?
The timing belt (also called a toothed belt or timing belt) is a toothed rubber belt that connects the engine's crankshaft to the camshaft(s). This belt ensures that the valves open and close at the correct time, synchronized with the movement of the pistons. Perfect timing is essential for a smoothly functioning engine.
Many modern engines have a so-called "interference engine". Have your timing belt replaced in time at a certified garage. This means the valves and pistons occupy the same space, but at different times. If the timing belt breaks, this timing is lost, and valves and pistons can collide, resulting in catastrophic engine damage.
Timing Belt Replacement: Intervals by Brand
Each car manufacturer has its own guidelines for timing belt replacement. These intervals are based on mileage and the belt's age. It's important to consider both factors – a timing belt can also wear out due to age, even if you drive few kilometers.
| Car brand | Replacement interval (km) | Replacement interval (years) |
|---|---|---|
| Volkswagen | 120.000 – 180.000 | 5 – 7 years |
| Toyota | 100.000 – 150.000 | 5 – 10 years |
| BMW | Often chain, no belt* | – |
| Peugeot | 120.000 – 180.000 | 6 – 10 years |
| Renault | 120.000 – 180.000 | 6 years |
| Ford | 160.000 – 240.000 | 8 – 10 years |
| Opel | 150.000 – 180.000 | 10 years |
| Audi | 120.000 – 180.000 | 5 – 7 years |
| Mercedes-Benz | Often chain, no belt* | – |
| Lemon | 120.000 – 160.000 | 6 – 10 years |
NB: These intervals are guidelines. Always check the service manual for your specific model for the exact replacement intervals. Some engines have a timing chain instead of a belt – this should generally last the life of the engine.
Warning Signs: How Do You Know Your Timing Belt Is Worn?
The problem with timing belts is that they often break without warning. However, there are some signs that can indicate wear:
1. Tapping noise from the engine compartment
A ticking or clicking sound from the engine compartment could indicate a loose timing belt or worn tensioner pulley. This sound often becomes louder when starting the engine or at high revs.
2. Engine Runs Irregularly
If the timing belt starts to slip, it can lead to incorrect valve timing. This manifests as rough engine running, rough idling, or loss of power.
3. Visual Wear
A visual inspection (to be carried out only by a professional) may reveal the following signs of wear:
- Cracks in the belt
- Shiny or glazed-looking belt surface
- Missing teeth
- Oil leak on the belt
- Stretched belt
4. Smoke development from the exhaust
Excessive smoke, especially when starting, could indicate a timing problem caused by a loose or slipping timing belt.
Consequences of a Broken Timing Belt
When a timing belt breaks while driving, the consequences are often catastrophic, especially with interference engines:
- Valve damage: Valves bend or break when struck by pistons
- Piston damage: Pistons can be damaged in the impact
- Cylinder head damage: The cylinder head may crack or deform
- Camshaft damage: The camshaft may be damaged
- Total engine damage: In severe cases, engine replacement is necessary
Repair costs for belt breakage: €3,000 to €8,000, depending on the severity of the damage and the engine type. This contrasts sharply with the preventative replacement cost of €450 to €750.
Timing Belt Replacement Costs
The cost of replacing a timing belt varies depending on the car make, model, and engine type. Below is an overview of the average costs in 2025:
| Component/Service | Price |
|---|---|
| Timing belt (material) | €80 – €200 |
| Tension roller and guide roller | €40 – €120 |
| Water pump (optional but recommended) | €60 – €150 |
| Labor costs (3-6 hours) | €250 – €450 |
| Totally complete | €450 – €750 |
Why also replace the water pump? In many cars, the water pump is driven by the timing belt. Because the labor time is the same (the belt has to be removed anyway), it's wise to replace the water pump at the same time. This prevents you from having to pay the same labor costs again a few years later.
What Is Replaced During a Timing Belt Service?
Professional timing belt maintenance involves more than just the belt itself. At FAAY Auto Groep, we replace the following as standard:
- Timing belt: The main belt that provides the timing
- Tensioner: Maintain proper tension on the belt
- Guide roller(s): Guide the belt along the correct route
- Water pump: Optional but highly recommended
- Auxiliary belts: If necessary and/or accessible
- Coolant: When replacing the water pump
All parts are replaced according to manufacturer guidelines, and we use only OEM or equivalent quality parts.
Timing Belt vs. Timing Chain: What's the Difference?
Not all cars have a timing belt. Some engines are equipped with a timing chain:
Timing belt
- Made of rubber with reinforcement
- Quieter in use
- Needs to be replaced periodically
- Cheaper to purchase
- Lighter weight
Timing chain
- Made of metal
- Could be noisier
- In principle it will last a motorcycle's lifetime
- More expensive to purchase
- Heavier weight
- Requires lubrication via engine oil
NB: Although timing chains last longer, they are not completely maintenance-free. Tensioners and guides can still wear out and may need replacing.
How to Prevent Timing Belt Problems?
- Maintain the maintenance schedule: Replace the belt according to the manufacturer's recommendations, both for mileage and age.
- Regular inspection: Have the timing belt visually inspected at every major service.
- Prevent oil leaks: Oil on the timing belt accelerates wear significantly.
- Quality parts: Always use OEM or high-quality aftermarket parts.
- Professional installation: Have the timing belt replaced only by certified mechanics.
- Replace complete set: Always replace the belt together with tensioners and guides.

Frequently Asked Questions About Timing Belt Replacement
How do I know if my car has a timing belt or chain?
This is stated in your car's maintenance booklet. You can also look up the VIN code with the manufacturer or contact FAAY Auto Groep for a free check. If your maintenance booklet lists a replacement interval for the "timing belt" or "toothed belt," your car has a belt.
Can I still drive if the timing belt is worn?
If you suspect the timing belt is worn (e.g., if the service interval is exceeded), the risk of engine damage is very high. We recommend stopping use of the car and having it towed to a garage. The potential damage from a broken belt (€3,000-€8,000) is much higher than the towing costs.
How long does it take to replace a timing belt?
Depending on the model and the belt's accessibility, the job typically takes 3 to 6 hours. For some models with engines that have many components or where the engine must be (partially) removed, it may take longer. We always provide you with a realistic estimated time in advance.
Do I also need to replace the water pump during a timing belt service?
This is highly recommended. In most cars, the water pump is driven by the timing belt. Because the labor time to access the water pump is the same (the belt has to be removed anyway), you'll save significantly on labor costs by replacing both components at the same time. Water pumps often have a similar lifespan to timing belts.
What happens if I exceed the replacement interval?
The risk of belt failure increases exponentially after the recommended replacement interval. Rubber deteriorates with age and exposure to temperature fluctuations, oil, and chemicals. A belt can appear "good" but suddenly break. With interference engines (most modern engines), this leads to engine damage costing between €3,000 and €8,000. It's a gamble that's definitely not worth the €500 savings.
