Which Subaru engines use timing chains?

Subaru engines that use timing chains rather than timing belts include the 2.4-liter turbocharged Boxer engine found in models like the Ascent, Outback, and Legacy. These engines rely on a timing chain to synchronize the opening and closing of the valves, providing a more durable and long-lasting solution compared to timing belts.


Understanding Subaru's Engine Designs


Subaru is known for its unique Boxer engine design, where the cylinders are horizontally opposed rather than in a traditional inline or V configuration. This layout provides a lower center of gravity, which enhances the vehicle's handling and stability. Subaru's Boxer engines come in various displacement sizes, ranging from 2.0 liters to 2.4 liters, and some are turbocharged for increased power output.


Timing Chains vs. Timing Belts


The primary difference between timing chains and timing belts is their durability and longevity. Timing chains are made of metal links and are designed to last the lifetime of the engine, while timing belts are made of reinforced rubber and typically need to be replaced every 60,000 to 100,000 miles.


Timing chains offer several advantages over timing belts, including:



  • Longer service life, reducing the need for costly replacements

  • Improved reliability and reduced risk of unexpected failure

  • Better resistance to wear and tear, especially in high-performance engines


However, timing chains can be more complex and expensive to manufacture, which is why some automakers opt for timing belts in certain engine designs.


Subaru Engines with Timing Chains


Subaru's latest generation of Boxer engines, including the 2.4-liter turbocharged engine found in models like the Ascent, Outback, and Legacy, utilize a timing chain system. This design choice provides enhanced durability and reliability for these high-performance engines.p>

Other Subaru engines that use timing chains include:



  • 2.0-liter Boxer engine (found in the Impreza, Crosstrek, and Forester)

  • 2.5-liter Boxer engine (found in the Outback, Legacy, and Ascent)

  • 2.4-liter turbocharged Boxer engine (found in the WRX and STI models)


By using timing chains, Subaru ensures that its engines can withstand the demands of everyday driving and high-performance use, providing customers with a reliable and long-lasting powertrain.

Can a timing chain last 300000 miles?


However, the timing chain isn't necessarily a maintenance item and can last the engine's life, provided you change the oil regularly and maintain the rest of the engine. Modern engines can last 300,000 miles or more with proper maintenance, and the timing chain can go that long, too.



How do I know if my Subaru has a timing belt or chain?


A timing chain is made of metal, so it tends to last a lot longer. It is housed in the engine and lubricated with engine oil. A timing belt is typically made of reinforced rubber, which can stretch and crack with old age. It is found outside the engine and is usually quieter than a timing chain.



How long does a Subaru timing chain last?


A timing chain is bulkier and louder; however, it does not require replacement. Though a repair might be necessary in some rare occasions, most timing chains last for the entire life of the engine.



What Subaru models have a timing chain?


Here are four signs that the timing belt on your car may need to be replaced. If you have a Subaru Outback, Forester or other non-STI vehicle from the 2014 model year or newer, your car is equipped with a timing chain that doesn't need regular maintenance.



What year did Subaru switch to timing chains?


Simply, then, a 1997 to 2011 Forester will have a timing belt, while any of the fourth-gen Foresters (from 2013 or later) will have a timing chain. And for a brief period from 2011 to 2012, the Forester was fitted with either a timing belt or a timing chain depending on which engine was fitted.



Does 2025 Forester have a timing belt or chain?


2025 Subaru Forester Engine Timing Chain.



What are the symptoms of a worn out timing chain?


These signs include:

  • Rattling Sound on Starting The Engine or Idling. A common finding in a vehicle with a bad timing chain is unusual rattling noise when the engine is started or when brakes are engaged.
  • Misfiring Engine.
  • Contaminated Engine Oil.
  • Check Engine Light.
  • Inability to Start The Engine.



What car models have timing chains?


Luxury Cars

  • Mercedes-Benz: Many Mercedes models, especially those with V6 and V8 engines, use timing chains.
  • BMW: BMW models like the 3 Series and 5 Series and vehicles with inline-six engines often come with timing chains.
  • Audi: The A4 and A6, especially with V6 engines, frequently feature timing chains.



Does the Kia Rio have a timing belt or chain?


Expert answer
It has a timing chain, so shouldn't need any maintenance, other than lubrication and a regular inspection of the chain tensioners.



How long does a Kia Rio timing chain last?


Timing chains can last anywhere between 150,000 and 200,000 miles before they require repair or sustain damage. But once they do, they must be replaced without fail as they can break off entirely, therefore causing the engine to fail.
