When should a Subaru timing belt be replaced?
In most Subaru models that still use a timing belt, replacement is typically recommended around 105,000 miles or about 8–10 years, whichever comes first. Some older Subaru engines called for 60,000 miles. Always confirm with your owner's manual or dealer to account for your specific model-year and engine.
This article explains how to determine whether your Subaru uses a timing belt or chain, the typical replacement intervals by model year, signs of belt wear to watch for, and steps to take when a replacement is due. Understanding these details helps prevent engine damage and keeps your vehicle reliable.
Belts versus chains in Subaru engines
Subaru has used both timing belts and timing chains across its model history. Most older EJ-series engines relied on timing belts and required periodic replacement. Many newer FA/FB-series engines use timing chains, which typically last longer but still require inspection and occasional service for tensioners and guides. The exact method depends on your engine code and year, so always verify via the owner’s manual or a trusted Subaru technician.
How to confirm your engine’s timing method
Check the engine code in the owner’s manual, under the hood, or via Subaru’s service resources for your VIN. The maintenance schedule will specify whether a belt or chain is used and when it should be serviced. If you’re unsure, ask a Subaru dealer or a qualified mechanic.
Typical replacement intervals for belt-driven Subarus
Before listing typical intervals, note that exact mileage can vary by model year and engine family. Use this as a general guide and always reference your manual.
- Older engines (EJ-series and some EZ-series) commonly had earlier belt-change recommendations, around 60,000 miles for some generations, with later revisions extending toward 90,000–105,000 miles depending on model and year.
- Most belt-driven Subarus from the mid-2000s to early-2010s specify about 105,000 miles (8–10 years) as a standard replacement interval, whichever comes first.
- Harsh operating conditions—such as frequent short trips, extreme temperatures, towing, or heavy loads—can accelerate belt wear, potentially prompting earlier inspection or replacement.
In short, the conventional guidance for belt-driven Subarus is 105,000 miles (8–10 years) for many models, with some older generations using a shorter 60,000-mile interval. Always verify your specific model’s schedule.
Signs your timing belt may need replacement
Knowing the warning signs helps you catch wear before a break, which can cause catastrophic engine damage on interference engines.
- Visible cracks, fraying, or glazing on the belt.
- Oil or coolant contamination on the belt surface, which can degrade the belt’s material.
- Unusual engine noises such as ticking, squealing, or chirping from the front of the engine area.
- Engine misfires, rough running, or loss of power that isn’t explained by another fault.
- Engine won’t start or stalls, especially if the belt has failed or slipped.
If you notice any of these signs, stop driving and have the vehicle inspected promptly by a qualified technician to prevent potential valve/ piston damage.
What to do as you approach the service interval
Planning ahead can save money and prevent breakdowns. Here are steps to take when your Subaru nears its belt-replacement window.
- Consult the owner’s manual or a dealership to confirm the exact interval for your model-year and engine code.
- Schedule service with a Subaru-certified shop or a trusted technician experienced with belt-driven engines.
- Ask about replacing related components at the same time, such as the water pump, tensioners, and idler pulleys, to reduce future labor costs.
Proactively replacing the belt along with associated components is standard practice and helps prevent unexpected breakdowns and major engine damage.
Are timing belts still relevant on newer Subarus?
Starting in many newer Subaru designs, timing chains began to replace belts in several engines (notably FA/FB-series engines). Chains typically require less frequent replacement, but chain-driven engines still have wear components such as tensioners and guides that may need service over time. Always verify whether your vehicle uses a belt or a chain, and follow the model-specific maintenance schedule.
Summary
For most Subaru models with a timing belt, plan replacement around 105,000 miles or 8–10 years, with some older generations requiring service as early as 60,000 miles. If your model uses a timing chain instead, the replacement interval is generally longer and more dependent on tensioner/guide wear. Always confirm the exact interval for your car in the owner’s manual or with a Subaru-certified technician. Regular inspections and replacing the belt (and related components) as recommended helps prevent costly engine damage and keeps your Subaru running smoothly.
What year did Subaru get rid of the timing belt?
But most prior to 2012 or 2010. Will be a belt driven engine now the belt driven engines of late were the EJ. Series that includes but not limited to the EJ18 EJ20 EJ22 and EJ25.
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.
How much does it cost to replace a timing belt in a Subaru Outback?
The cost to replace a Subaru Outback timing belt typically ranges from $650 to over $1,300, depending on the vehicle's model year, the parts used, and where the service is performed. Independent repair shops are generally less expensive ($650-$1,200), while dealerships tend to have higher costs (often above $1,100) due to using official OEM parts and specialized labor.
Factors affecting the cost
- Location: Labor rates vary significantly by region, with major metropolitan areas usually having higher costs.
- Service provider: Dealerships charge more than independent mechanics due to factors like specialized training and using official Subaru parts.
- Parts: Using OEM (Original Equipment Manufacturer) parts is more expensive, while aftermarket parts from independent shops can lower the overall price.
- Vehicle model year: Older models may have higher labor costs due to a more complex or less common engine design, while newer models may have different part costs.
- Additional parts: It is often recommended to replace other components like the water pump, tensioner, and idler pulleys at the same time, which adds to the total cost but is more cost-effective in the long run.
How to get an accurate estimate
- Call a few independent repair shops and dealerships in your area.
- Ask for a detailed quote that includes both parts and labor.
- Inquire about the specific parts that will be used (OEM vs. aftermarket) and ask if a timing belt kit with the water pump and other related components is being used.
- Ask if a timing chain engine is a factor for your specific model, as this significantly increases the cost and labor time, and it is a different system altogether.
