When should the timing belt be changed on a Ford Focus diesel?
The timing belt on most Ford Focus diesels should be replaced around 100,000 miles (160,000 km) or roughly every 6–8 years, whichever comes first. Exact intervals vary by engine variant and market, so check your owner's manual or ask a Ford dealer for your VIN.
Below is a detailed guide on identifying the correct interval for your car, what factors affect belt wear, the signs of a worn belt, and how to plan maintenance to avoid a breakdown.
Engine variants and belt systems
Most Focus diesel engines used a timing belt to drive the camshaft(s), notably the 1.6 TDCi (Duratorq DV6) and the 2.0 TDCi. While belts are common, some later models may use alternative timing-drive designs or have changes in the engineering. Always confirm the exact interval for your vehicle’s year, engine variant, and market by consulting the manual or a Ford dealer for your VIN.
Recommended replacement interval
In general, plan a belt replacement around 100,000 miles (160,000 km) or 6–8 years, whichever comes first. Some engines or regions specify different intervals, such as 90,000 miles or 125,000 miles; the definitive source is your vehicle’s service schedule in the owner’s manual or Ford’s official service information for your VIN. If you’re unsure or have unclear maintenance history, err on the side of replacing the belt within the 100k mile window to minimize risk.
Signs of wear
Watch for cracking, fraying, or glazing on the belt surface, oil or coolant contamination that can degrade the belt, or a failing tensioner and idlers. Unusual engine noises such as chirping or squealing, misfires, or a drop in power can also indicate belt issues. If you notice any of these signs, stop driving and have the belt inspected by a qualified mechanic as soon as possible to avoid catastrophic engine damage.
What to do if the belt is due or overdue
When a belt is approaching or past the recommended interval, schedule service with a qualified technician. A timing belt replacement typically includes the belt plus tensioner and idlers; many shops also replace the water pump and seals, since these parts share the same service interval and a failure can compromise the new belt. Use OEM or high-quality aftermarket parts appropriate for your engine and follow the manufacturer’s service sequence and torque specs.
Maintenance and life-extension tips
Keep cooling systems in good condition and address leaks promptly, as overheating or fluid contamination can degrade the belt. Have the belt drive system inspected at major service intervals, especially after high-mileage or harsh driving. Maintain clean fuel and proper engine oil to minimize stress that can indirectly affect belt wear.
Summary
For most Ford Focus diesel models, plan timing belt replacement around 100,000 miles (160,000 km) or about 6–8 years, with exact figures varying by engine variant and market. Always verify the interval in the owner’s manual or with a dealer for your VIN, and consider replacing supporting components like the water pump and tensioners during the job to reduce future labor costs. Regular inspections help prevent surprise belt failure and potential engine damage.
What years of Ford Focus to stay away from?
The Ford Focus years to avoid are 2012-2016, due to major issues with the automatic PowerShift transmission. Other years to avoid include 2007 and 2008 for electrical and steering problems, and 2017–2018, which had lingering transmission and other issues, although fewer than previous years.

Problematic model years
- 2007–2008: These models are associated with faulty electrical systems, door handle failures, and frequent issues with steering and suspension.
- 2012–2016: This range is considered the most problematic, primarily due to the PowerShift dual-clutch automatic transmission, which frequently failed and is expensive to repair. Problems included hesitation, jerking, and complete failure, often before 100,000 miles. Some models in this period also had issues with power steering and electrical glitches.
- 2017–2018: While improved, these years still saw some lingering transmission problems and sporadic electrical issues.
What to look for in other model years
- Manual transmission: The problematic issues mainly affected the automatic versions of the third-generation Focus (2012-2018). Models with a manual transmission from this period are generally considered more reliable.
- Earlier models (pre-2012): While not entirely trouble-free, models before 2012, especially around 2011, are often seen as more reliable than their successors due to simpler transmissions.
- Later models (post-2016): The 2018 and 2019 models are often praised for improved reliability and handling.

How much does it cost to change a timing belt on a Ford Focus?
The cost to replace a Ford Focus timing belt typically ranges from $409 to over $1,000, depending on the specific model year and the service center. Independent shops often fall in the lower end of the range, while dealerships can be more expensive. The total cost depends on labor, which is high due to the location of the belt, and the parts included in the job, with a full kit including the belt, pulleys, tensioner, and water pump being recommended.
Cost breakdown
- Price range: Expect to pay between $409 and $919 for a timing belt replacement, including parts and labor. Some estimates, especially from dealerships or for older models, can be higher, reaching $1,000 to over $1,400.
- Independent vs. dealership: An independent shop might cost between $733 and $828 for a newer model. Dealerships often charge more, potentially from $945 to $1,053 for an older model, due to using OEM parts and higher labor rates.
- Parts and labor:
- Labor: The labor is the most significant cost because the timing belt is buried deep in the engine, requiring 3-6 hours of work.
- Parts: A full timing belt kit (including the belt, idler pulleys, and tensioner) typically costs between $100 and $350. It is highly recommended to replace the water pump at the same time to avoid future, more costly repairs, as the labor for this job is minimal when the belt is already being replaced.
Factors that influence the final price
- Your car's model year: Older vehicles may have higher costs.
- The service provider: Dealerships and independent shops have different pricing structures.
- Parts quality: Using aftermarket parts can lower the price, while OEM parts are generally more expensive.
- Additional services: The cost will increase if you choose to replace other components like the water pump, though this is a recommended and cost-effective practice in the long run.
How often should a timing belt be changed on a diesel engine?
Most vehicle manufacturers recommend timing belt replacement between 60,000–160,000 km, depending on make and model.
How long does it take to change the timing belt on a Ford Focus?
10 years
Ford recommend it should be replaced at 150,000 miles or 10 years. Many of you have seen the belt disintegrate, sometimes ruining the engine, or needing replacement well before 150k miles.
