Do Subaru timing chains need to be replaced?
Subaru vehicles are known for their reliability and longevity, but like any car, they require regular maintenance to keep them running smoothly. One common question among Subaru owners is whether the timing chain in their vehicle needs to be replaced. In this article, we’ll explore the role of the timing chain, how it differs from a timing belt, and whether replacement is necessary.
What Is a Timing Chain and How Does It Work?
The timing chain is a crucial component of your engine. It synchronizes the rotation of the crankshaft and camshaft, ensuring that the engine’s valves open and close at the right times during each cylinder’s intake and exhaust strokes. This precise timing is essential for the engine to run efficiently and avoid damage.
Unlike a timing belt, which is made of rubber and reinforced with fibers, a timing chain is made of metal. This makes it more durable and less prone to wear and tear under normal operating conditions.
Do Subaru Timing Chains Require Replacement?
In most cases, Subaru timing chains are designed to last the lifetime of the vehicle. Unlike timing belts, which typically need to be replaced every 60,000 to 100,000 miles, timing chains are built to withstand the rigors of long-term use. However, there are exceptions to this general rule.
- Wear and Tear: Over time, the timing chain can stretch or wear out, especially if the vehicle has high mileage or has not been properly maintained.
- Lack of Maintenance: Neglecting regular oil changes can lead to insufficient lubrication, causing the timing chain to wear prematurely.
- Unusual Noises: If you hear rattling or ticking noises coming from the engine, it could indicate a problem with the timing chain or its tensioner.
When Should You Replace a Timing Chain?
While timing chains are generally low-maintenance, there are situations where replacement may be necessary. Here are some signs that it might be time to replace your Subaru’s timing chain:
- The engine is making unusual noises, such as rattling or ticking.
- The engine is misfiring or running poorly.
- The check engine light is on, and diagnostics point to timing chain issues.
- The vehicle has very high mileage, and the timing chain has never been inspected or replaced.
If you experience any of these symptoms, it’s important to have your vehicle inspected by a professional mechanic. Ignoring timing chain issues can lead to severe engine damage and costly repairs.
How to Extend the Life of Your Timing Chain
To ensure your Subaru’s timing chain lasts as long as possible, follow these maintenance tips:
- Stick to a regular oil change schedule using high-quality oil recommended by Subaru.
- Pay attention to any unusual engine noises and address them promptly.
- Have your vehicle inspected regularly by a trusted mechanic to catch potential issues early.
Conclusion
In summary, Subaru timing chains are designed to be durable and typically do not require replacement under normal conditions. However, factors such as high mileage, lack of maintenance, or unusual engine noises may necessitate a replacement. By following a proper maintenance routine and addressing issues promptly, you can help ensure your Subaru’s timing chain remains in good condition for the life of the vehicle.

Frequently Asked Questions
How much does it cost to replace a timing chain on a Subaru Outback?
$1127 - $1255. “Dealer” refers to service centers that specialize in one or two makes and sell those vehicles.
How to tell if a timing chain needs replacing?
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.
Do timing chains last a lifetime?
Modern vehicles often rely on timing chains instead of traditional timing belts, and for a good reason: timing chains are durable, reliable, and built to last the lifetime of the engine—at least in theory!
Do timing chains really need to be replaced?
Timing chains do wear, but are not generally replaced unless they are noisy or giving issues. If it's not rattling around or causing you issues, leave it alone!
Can a timing chain last 200,000 miles?
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.
What year did Subaru switch to timing chains?
Commonly found on most Subaru vehicles built in the 1990s and early 2000s, the EJ family of engines all feature timing belts. But, in 2010, the new FB family of engines featured an all-new design including a timing chain.
When should the Subaru timing chain be replaced?
However, these are still the sorts of durable automotive components that can last for a long time, especially for very conscientious drivers. They may only need to get new timing chains after driving for a full one hundred and twenty thousand miles.
How do I know if my timing chain is worn?
If it does it's best to replace. It the third symptom is poor. Performance a stretched timing belt or chain could eventually lead to skipping a tooth on one of the sprockets.
Which Subaru models have timing chains?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
Do all Subarus have timing chains?
Depending on what kind of engine your Subaru has, it may be equipped with either a timing belt or a timing chain. These two parts serve the same function, but require different attention. A timing belt is rubber-based, and will need to be replaced at certain maintenance intervals.
