What year did Subaru go to timing chain?
Subaru, a brand known for its reliable and durable vehicles, has made significant advancements in engine technology over the years. One of the most notable changes was the transition from timing belts to timing chains in many of their models. This article explores when Subaru made this switch and what it means for vehicle owners.
The Transition from Timing Belts to Timing Chains
Subaru began transitioning from timing belts to timing chains in 2011. This change was introduced with the new generation of engines, specifically the FB series engines, which replaced the older EJ series engines. Timing chains are now a standard feature in most Subaru models equipped with these newer engines.
Why Did Subaru Make the Switch?
The decision to move from timing belts to timing chains was driven by several factors:
- Durability: Timing chains are generally more durable than timing belts and can last the lifetime of the engine with proper maintenance.
- Reduced Maintenance Costs: Unlike timing belts, which require periodic replacement (usually every 60,000 to 100,000 miles), timing chains do not need regular replacement, saving owners time and money.
- Improved Engine Performance: Timing chains provide more precise timing, which can enhance engine performance and efficiency.
Which Subaru Models Have Timing Chains?
Subaru models equipped with the FB series engines, such as the Subaru Forester, Outback, and Impreza from 2011 onward, feature timing chains. However, older models with EJ series engines still use timing belts. If you're unsure about your vehicle's engine type, consult your owner's manual or contact a trusted mechanic.
What Does This Mean for Subaru Owners?
For Subaru owners, the switch to timing chains means fewer maintenance concerns and potentially lower long-term costs. However, it's still essential to maintain your vehicle properly, as timing chains can wear out or fail if the engine is not well-maintained. Regular oil changes and inspections are crucial to ensure the longevity of the timing chain and the engine as a whole.

Frequently Asked Questions
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 is the biggest problem with Subaru engines?
One of the most notorious issues plaguing Subaru vehicles is head gasket leaks, particularly in older models with the EJ series engines. These leaks can lead to coolant loss, overheating, and potential engine damage if left untreated.
What Subaru models have a timing chain?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
When did Subaru go to timing chains?
2011
2011 was the first year for the newest version of the 2.5L normally aspirated engine. Years previous to 2011 the 2.5L, as did all Subaru flat four engines, used a timing belt. Beginning in 2011 the 2.5L uses a timing chain.
Do Subaru timing chains need to be replaced?
They may only need to get new timing chains after driving for a full one hundred and twenty thousand miles. It should take years for most drivers to get to that point. Customers who recently purchased used Subaru vehicles should usually get the automotive timing chains checked.
What are the symptoms of a bad timing chain?
Misfiring, poor idle, and rough running could mean the chain has jumped a tooth and the timing is off. Replacement is urgent, because the chain could break at any point, and the engine could be damaged from incorrect valve timing.
What year did Subarus have bad head gaskets?
The Subaru Head Gasket Problem
A number of Subaru models are affected, however the most common failures include the 2.5 Liter SOHC engine used in the late 1999-2004, Forester, Impreza, Outback and Legacy. Signs and symptoms of engine head gasket failure include: Engine overheating.
What years did Subaru have CVT problems?
The models and years that were affected mainly by transmission issues are:
- Crosstrek, 2013 – 2015.
- Crosstrek Hybrid, 2014 – 2015.
- Forester (2.0 and 2.5 liter engines), 2014 – 2015.
- Impreza, 2012 – 2015.
- Legacy, 2010 – 2015.
- Legacy 3.6L V6, 2015.
- Outback, 2010 – 2015.
- Outback 3.6L V6, 2015.
What year did Subaru have engine problems?
Subaru WRX and WRX STI: 2008-2014 Models
The performance-oriented Subaru WRX and WRX STI from 2008 to 2014 unfortunately did not escape their own set of difficulties. These cars were plagued with engine problems.
How do I know if my Subaru has a timing belt or chain?
Cars with a timing belt have a plastic cover near the engine block (often to the left-hand side), which provides easy access to the belt. It needs changing at regular intervals, which is why the removable cover is necessary. In cars with a timing chain, you won't see a plastic cover.
