Does WRX have a timing belt or chain?
The short answer: modern Subaru WRX models use a timing chain, not a timing belt. Subaru has moved to chain-driven timing across its newer WRX line, including the current 2.4-liter turbo engines. Some very early WRX variants used different configurations, so verify your specific year and engine code for certainty.
Engine families and timeline
Subaru’s WRX lineage has cycled through several engine designs. In recent years, the company has standardized on chain-driven timing for its performance models, which affects maintenance needs and replacement intervals compared with timing belts.
Current generation: FA24 2.4L turbo
Beginning with the 2022 WRX, Subaru introduced the FA24 2.4-liter turbocharged flat-four. This engine is timing-chain driven, not belt-driven. Chains generally last longer than belts, but they still require periodic inspection, particularly of tensioners and guides, and regular oil changes to keep the system in good working order.
Previous generation: FA20D 2.0L turbo
Earlier WRX models (roughly 2015–2021) used the FA20D 2.0-liter turbocharged engine, which is also chain-driven. There is no timing belt replacement interval to follow for this engine, but owners should adhere to the standard maintenance schedule and be attentive to any unusual noises or timing-related symptoms as the vehicle ages.
Older WRX iterations and engine options
Earlier WRX configurations varied by year and market, and some non-standard setups may have differed in their timing mechanism. If you own or are considering a vintage WRX, confirm the exact engine code and service requirements from the owner's manual or a dealer to know whether a belt or chain applies and what replacement-related maintenance is needed.
Maintenance implications
Because WRX engines in the modern era are chain-driven, there is no routine belt replacement. However, timing chains can wear, and tensioners or guides can fail over time. Regular maintenance—especially oil changes using the recommended viscosity and quality oil—helps keep chain tensioners properly lubricated. If you hear unusual chatter on startup, run rough, or notice decreased performance, have a mechanic inspect the timing chain and related components.
What to do if you are unsure
To confirm your specific WRX’s timing arrangement, check the vehicle’s engine code and year in the owner's manual or VIN lookup. A Subaru dealer or a qualified mechanic can provide the exact configuration for your model and advise on any maintenance or potential wear-related concerns based on mileage and usage.
Summary
Across the modern WRX lineup, Subaru uses timing chains rather than belts for the engines currently in production (FA20D and FA24). This means no belt-change intervals for recent models, though chain wear and tensioner issues can still arise with age and mileage. Always verify with your model year and engine code to ensure accurate maintenance guidance.
Does a 2016 Subaru WRX have a timing belt?
Timing belts for your 2016 Subaru WRX Sti don't last forever, so it's a good idea to start checking on it after 60,000 miles, especially if you still have the factory belt, and replace it at 100,000 miles It's best to upgrade to a better belt that's made with precision-molded teeth, reinforced polymers, and heat- ...
When did the Subaru WRX switch to timing chain?
EJ engines use timing belts. FA and FB use chains. From 2015 onward the only EJ-engined Subaru was the STI. Every other model transitioned to either FA or FB between 2011 and 2015.
When to change timing belt subaru wrx?
The Subaru WRX timing belt replacement interval is typically at 105,000 miles or 105 months (about 8.75 years), whichever comes first. However, it is crucial to check your specific owner's manual for the exact interval for your model year, as the interval can vary. Other sources suggest a different interval like 96,000 miles/96 months for some newer models (2018 and newer).
Key points
- Time vs. mileage: Both mileage and age are important. A belt can deteriorate over time even with low mileage, so age is a significant factor for replacement.
- Interference engine risk: The WRX has an interference engine, meaning if the timing belt breaks, the pistons and valves can collide, causing severe and costly engine damage.
- Associated parts: It is highly recommended to replace related parts when the timing belt is replaced. This includes the water pump, idlers, and tensioner, as they are often accessed at the same time.
- Consult the manual: The owner's manual is the most authoritative source for your specific vehicle's maintenance schedule. If you can't find it, you may be able to download a digital copy from the Subaru website.
Which Subaru has a timing chain?
2010-2012 Outbacks with the 2.5 SOHC (EJ253) have a timing belt. 2013-2014 Outbacks with the 2.5 DOHC (FB25) have a timing chain. And the Outbacks with the 3.6 (EZ36) have chains as well.
