Which Subaru models have a timing chain?
Most modern Subaru models use timing chains rather than traditional timing belts. This shift is tied to Subaru’s FA/FB engine family introduced in the early 2010s, which covers the majority of current models.
What changed in Subaru engines
Subaru historically used timing belts on many EJ-series engines, which required belt replacement at regular intervals. Beginning around 2011–2012, Subaru expanded its lineup with FA/FB boxer engines that rely on timing chains. Chains generally offer longer service life than belts, though they do have tensioners and guides that can wear over time. When evaluating a used Subaru, checking the exact engine code helps determine whether a belt or a chain is present and what maintenance to expect.
Engine families that use timing chains
The engines in Subaru’s newer lineup—FA/FB family boxer engines—are chain-driven. This includes most 2.0L and 2.5L variants, as well as the newer 2.4L turbo motors. The practical effect is that many current models no longer require belt replacements as part of regular maintenance.
- FB20/FB25 family (2.0L and 2.5L non-turbo/regular-engines)
- FA20/FA24 family (2.0L turbo and 2.4L turbo engines)
- Recent 2.4L engines (FA24) used in higher-performance and newer crossovers/coupes
Note: Some older Subarus with EJ-series engines (predating the FA/FB transition) used timing belts and required periodic belt maintenance. If you’re purchasing a used model, confirm the exact engine code and year to verify whether a chain or belt is installed.
Model-by-model overview (current lineup)
Here’s a snapshot of common, current-generation Subaru models and the engines they use that rely on timing chains. Year-to-year variations can occur, so always verify the specific vehicle’s engine code.
- Impreza (2012–present): generally equipped with FA/FB engines that use timing chains
- Forester (2014–present): FA/FB engines with timing chains
- XV Crosstrek (2013–present): FB20/FB25 family with timing chains
- Outback (2015–present): FB/FB25 engines with timing chains
- Legacy (2010s–present): FA/FB engines with timing chains
- WRX (2015–present): modern variants use FA/FB turbo engines with timing chains
- BRZ (2012–present): FA20-based, timing chain
- Ascent (2019–present): FA24-based, timing chain
Bottom line: in Subaru’s current lineup, timing chains are standard on the engines in most mainstream models, especially those built on the FA/FB family. If you’re shopping used, verify the engine code to confirm belt vs chain maintenance implications for your specific year and trim.
Summary: For buyers and owners, the practical takeaway is that most contemporary Subarus use timing chains, reducing the need for belt-replacement maintenance. Always check the exact engine code and year to confirm maintenance requirements, especially when evaluating older models that predate the FA/FB transition.
