How long do Subaru timing belts last?
Subaru timing belts typically last about 100,000 miles (160,000 kilometers) under normal driving, with a common replacement interval of around 105,000 miles or 7 years, whichever comes first. The exact lifespan depends on the engine and driving conditions, so always check your owner’s manual for the model-specific schedule.
What determines belt life
The lifespan of a timing belt hinges on a combination of engine design, how you drive, and how well the belt system is maintained. Belt-driven Subaru engines rely on pulleys, tensioners, and water pumps that can wear over time, while some Subarus use timing chains instead of belts, which follow different maintenance patterns. Regular inspections and adherence to the vehicle’s official schedule are key to preventing failure.
Typical replacement interval for belt-driven Subarus
Here is a snapshot of the standard maintenance window for most belt-driven Subaru engines. The exact number can vary by model, but the following reflects common guidance found in many Subaru service schedules.
- 105,000 miles (about 168,000 kilometers) or 7 years, whichever comes first, as a general guideline for many belt-driven Subaru engines.
Engineers design intervals around wear of the belt material, tensioners, and the water pump, and owners should always confirm the precise interval for their specific model and year in the official owner’s manual or with a Subaru dealer.
Signs your timing belt may be nearing or at end of life
Between scheduled replacements, pay attention to symptoms that can indicate belt wear or related component failure. Prompt attention can prevent catastrophic engine damage.
- Cracked, frayed, or glazed belt appearance or obvious fraying on the belt’s edges.
- Squealing, chirping, or ticking noises from the front of the engine, often coming from the belt area or tensioner.
- Difficulty starting, misfiring, or rough idling that coincides with belt wear or knock from timing irregularities.
- Oil leaks around the belt area, which can contaminate the belt or degrade tensioner components.
- Visible coolant or water pump seepage near the belt drive if the water pump shares the belt system.
If you notice these issues, stop driving if the belt fails or you suspect a problem, and arrange a professional inspection promptly.
Costs and what to expect during a timing belt replacement
Replacement costs can vary by region, shop, and whether additional parts are replaced at the same time. Many owners opt for a timing belt service that includes the water pump and other wear-prone components, since these parts are often accessible during the job and have similar service life.
- Typical price range in the United States for a timing belt replacement with water pump and basic labor: about $600 to $1,000. Dealer prices can be higher.
- Without water pump or additional parts, or at independent shops, costs may be lower but vary by location and vehicle.
- Expect to pay more if extra items are needed, such as new tensioners, pulleys, seals, and coolant, which are commonly included in a full belt-service package.
Planning ahead and budgeting for this service is wise, as a timing belt failure can cause severe engine damage. Check with a Subaru-certified technician to get an precise quote for your exact model and condition.
Model-specific notes
Engine designs and maintenance reminders
Some Subaru engines use timing belts, while others use timing chains. Chains generally do not have a fixed mileage replacement interval, but chains and guides wear over time and may require replacement if noise, slack, or performance issues appear. Always verify the exact configuration and recommended service schedule for your model by checking the owner’s manual or contacting a Subaru dealer. If your car has a belt-driven timing system, follow the belt interval specified for your engine family and consider proactive replacement if you drive in severe conditions.
Summary
For most Subaru models with timing belts, you should plan on a belt replacement around 105,000 miles or 7 years, whichever comes first, and be mindful of signs of wear between services. Belt-driven engines require proactive maintenance, while some newer Subarus use timing chains with different service considerations. Always refer to your specific model’s owner’s manual and consult a qualified technician to confirm the correct interval and to obtain an accurate cost estimate. Regular inspections and timely replacement help prevent costly engine damage and keep your Subaru running reliably.
Do subarus have timing belt issues?
Just like rubber accessory belts under the hood, the timing belt may stretch and crack over time. And since modern Subaru engines are interference engines, that means that a broken timing belt could cause severe damage to the engine! That's why it's crucial to get the timing belt on your Subaru changed before it fails.
How do I know if my Subaru needs a new timing belt?
A failing timing belt may show a myriad of symptoms, such as noises coming from the front of the vehicle, engine misfires, and decreased engine performance. In many situations, if the timing belt breaks, the engine will no longer run, and the engine will not restart without replacing the timing belt.
What year to stay away from a Subaru Outback?
Years to avoid for the Subaru Outback include 2010–2014, which had widespread CVT, oil consumption, and oil leak issues, and 2018, which had recalls and reliability concerns. Additionally, some sources recommend avoiding the 2005–2007 models due to head gasket problems and the 2020 model, which had electrical and windshield issues.
Years to avoid
- 2010–2014: These models are frequently cited for significant transmission issues (CVT), oil consumption, and general reliability problems. The 2010 model specifically had issues with the torque converter locking up.
- 2018: This year saw recalls and owner complaints related to oil consumption, exhaust components, and electrical issues.
- 2005–2007: These models are known for head gasket failures, which can cause coolant and oil leaks.
- 2020: This model year is associated with a high number of electrical problems, including dead batteries and stalling, as well as issues with the windshield cracking from small chips.
Other potential problem years
- 2013: Frequently mentioned for oil consumption issues.
- 2015: Some reports list it with electrical and engine problems.
- 2017: Reliability issues were noted.
Can a timing belt last 150,000 miles?
Timing belts have a limited lifespan, and most manufacturers recommend replacing them between 60,000 and 100,000 miles. However, this number can vary depending on the make and model of your vehicle, driving habits, and environmental conditions.
