When should the timing chain be replaced on a Subaru Forester?
The timing chain on a Subaru Forester should typically be replaced between 60,000 to 100,000 miles, depending on driving conditions and maintenance history. Replacing the timing chain at the recommended interval helps ensure the engine continues to operate smoothly and efficiently.
What is the Timing Chain and Why is it Important?
The timing chain is a critical component in the Subaru Forester's engine that synchronizes the opening and closing of the intake and exhaust valves with the movement of the pistons. This precise timing is essential for the engine to operate properly and deliver optimal performance, fuel efficiency, and emissions. Over time, the timing chain can stretch, wear out, or even break, which can lead to serious engine damage if not addressed.
Signs the Timing Chain Needs Replacement
There are several signs that may indicate the timing chain in a Subaru Forester needs to be replaced, including:
- Rattling or ticking noise from the engine - This can be a sign of a worn or loose timing chain.
- Decreased engine performance - A faulty timing chain can cause the engine to run rough, lose power, or experience misfiring.
- Check engine light illumination - The engine control module may detect issues with the timing chain and trigger the check engine light.
- Oil leaks near the timing chain cover - Worn seals around the timing chain can cause oil leaks.
If you notice any of these symptoms, it's important to have your Subaru Forester inspected by a qualified mechanic as soon as possible to prevent further damage to the engine.
Timing Chain Replacement Procedure
Replacing the timing chain on a Subaru Forester is a complex and labor-intensive process that typically requires the removal of the engine's front cover, camshafts, and other components. This job is best left to experienced Subaru technicians who have the proper tools and expertise to ensure the new timing chain is installed correctly and the engine is properly timed.
By being proactive and replacing the timing chain at the recommended interval, Subaru Forester owners can help ensure their vehicle continues to deliver reliable and efficient performance for many miles to come.
Does a Subaru Forester have a timing chain or belt?
Newer models use timing belts made of polyurethane and Kevlar for long life and durability.
How do I know if my timing chain needs replacing?
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.
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.
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.
How do I know when my 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.
What year did Subaru change 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.
Which Subaru Forester has a timing chain?
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.

How long does a timing chain last in a Subaru Forester?
A timing belt is rubber-based, and will need to be replaced at certain maintenance intervals. 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.
At what mileage should a timing chain be replaced?
Timing chains are designed to last a long time, typically between 100000 to 200000 miles (or about 160000 to 320000 kilometers). Unlike timing belts, which require regular replacement, timing chains generally do not have a specific replacement interval.
