Does Subaru have chain or belt?

Subaru uses both timing belts and timing chains. The answer depends on the engine and generation: older Subarus largely used belts, while many newer engines use chains. If you’re unsure about a specific model, check the engine code and the owner's manual or ask a dealer for confirmation.

Belts in Subaru’s older engines

The following list highlights the engines traditionally driven by a timing belt. Variations can occur by market and year, so verify for your exact vehicle.

• EJ-series engines (produced primarily in the 1990s through the late 2000s), including EJ20, EJ22, and EJ25, which used timing belts

For owners of older Subarus with a belt-driven timing system, plan for periodic belt replacement and accompanying water-pump service to avoid catastrophic engine damage if the belt fails.

Chains in Subaru’s newer engines

In recent generations, Subaru has shifted toward timing chains on most of its mainstream engines. Chains generally require less frequent maintenance beyond routine oil changes, though wear and tensioner issues can still arise over time.

• FA family engines (2.0L), used in models such as newer WRX and related platforms; timing chain-driven


• FB family engines (2.0L/2.5L variants), used in models like Forester, Impreza, and Outback; timing chain-driven


• EZ36 engine (3.6L H6), used in some Outback and larger Subaru models; timing chain-driven

For owners of newer Subarus, the timing chain is designed for longer service life, but chain-related issues—such as tensioner wear or guidance wear—can occur if maintenance is neglected. Always consult the service schedule for your exact engine code.

Maintenance considerations and practical guidance

Understanding whether your Subaru uses a belt or a chain has real maintenance implications. Belt-driven engines require a scheduled belt replacement, typically around 100,000 miles (or as specified by the manufacturer), and are often replaced together with the water pump due to accessibility and preventative maintenance. Chain-driven engines usually do not have a fixed replacement interval, but chains and associated components (tensioners, guides) can wear over time and may require inspection or replacement after high mileage or unusual noise.

Specific guidance depends on the model year and engine code. If you’re buying used, request the service history, confirm the engine family, and verify when the belt or chain was last inspected or replaced. If buying new, follow the current owner’s manual and dealer recommendations for maintenance intervals.

What this means for Subaru owners

In summary, Subaru’s approach has evolved: belts were common on older EJ-era engines, while modern FA/FB/EZ engines use timing chains. This shift generally reduces preventive maintenance needs, but it does not eliminate the importance of regular inspections and following the manufacturer’s service schedule. If you’re unsure about your specific model, a quick VIN-based check with a dealer or a trusted mechanic will confirm which system drives your timing.

Summary

Subaru employs both timing belts and timing chains, depending on the engine and generation. Belt-driven timelines are associated with older EJ-series engines, while newer FA/FB/EZ designs use chains. Always verify with the exact engine code and owner’s manual, and follow the recommended maintenance schedule to protect the engine.

Do subarus use chains?

Should I use snow chains on my Subaru? The simple answer: no. Due to Subaru's Symmetrical All-Wheel Drive system, adding snow chains to your tires is not necessary, nor recommended.

Does Subaru use a timing belt or chain?

Subaru uses both timing belts and chains, depending on the model and year. Newer models, especially those from 2013 or later, generally use a durable timing chain that doesn't require replacement. Older models, however, often have a rubber timing belt that needs to be replaced at specified intervals (typically around every 100,000 miles) to prevent severe engine damage. To be sure, always check your owner's manual for your specific vehicle. 
Timing chain (newer models)

• Function: A permanent metal chain that connects the engine's moving parts. 
• Maintenance: Does not require regular replacement; it is designed to last the life of the engine. 
• Models: Most Subaru models from around 2013 and newer have a timing chain. This includes most 4-cylinder engines (FB and FA series) and 6-cylinder engines (EZ series). 

Timing belt (older models)

• Function: A rubber belt that keeps engine components in time. 
• Maintenance: A wear item that needs to be replaced at manufacturer-recommended intervals to avoid failure. 
• Models: Found in older Subaru models, such as those with EJ series engines. 
• Failure risk: Since many modern Subaru engines are interference engines, if the belt breaks, it can cause catastrophic damage to the engine. 

How to check your Subaru

• Consult your owner's manual: This is the most reliable way to determine which type of system your vehicle has and its maintenance schedule. 
• Look for visual cues (for some models): On certain models, the location of the oil filter can be an indicator. If it's near the oil cap, you likely have a timing chain. 
• Know your model year: Generally, if your Subaru is from 2013 or newer, it has a chain. If it is older, it may have a belt. 

Does the 2025 Subaru Forester have a timing belt or chain?

The 2025 Subaru Forester uses a timing chain, not a timing belt. Subaru models have used timing chains since 2013, and they are generally more durable than belts.

• What it is: The timing chain is a metal chain that connects the engine's crankshaft and camshafts to ensure they are synchronized. 
• Maintenance: Timing chains are designed to last the lifetime of the engine and typically do not require regular replacement, unlike a timing belt which needs periodic replacement. 
• Signs of a problem: If the timing chain is stretching or failing, it can cause issues like a check engine light, excessive engine noise, or a no-start condition if the chain breaks.

What year does Subaru have a timing chain?

The six-cylinder or H6 engines if you got a 3 L or 3.6 L Outback or a Tribeca you have a timing chain. Now not to be confusing. But the EG33. The 3.3 L H6 found in this Subaru. SVX.
