How long does a timing chain last in a Subaru Forester?
The timing chain is a critical component of your Subaru Forester's engine, ensuring that the camshaft and crankshaft are synchronized for optimal performance. Unlike timing belts, timing chains are designed to last much longer, but they are not immune to wear and tear. In this article, we’ll explore how long a timing chain typically lasts in a Subaru Forester, signs of wear, and tips for maintenance.
Typical Lifespan of a Timing Chain
In most Subaru Foresters, the timing chain is designed to last the lifetime of the vehicle, which can often exceed 200,000 miles if the car is well-maintained. Unlike timing belts, which usually require replacement every 60,000 to 100,000 miles, timing chains are made of durable metal links that are less prone to breaking or wearing out under normal conditions.
However, the actual lifespan of a timing chain can vary depending on several factors, including driving habits, maintenance routines, and the overall condition of the engine. Regular oil changes are especially important, as clean oil helps to lubricate the chain and prevent premature wear.
Signs Your Timing Chain May Need Attention
While timing chains are built to last, they can still develop issues over time. Here are some common signs that your timing chain may need inspection or replacement:
- Rattling Noise: A loose or worn timing chain can produce a rattling sound, especially during startup or idling.
- Engine Misfires: If the timing chain stretches or skips a tooth, it can throw off the engine's timing, leading to misfires.
- Check Engine Light: A faulty timing chain can trigger the check engine light, often due to timing-related error codes.
- Reduced Engine Performance: A failing timing chain can cause a noticeable drop in power and fuel efficiency.
Maintenance Tips to Extend Timing Chain Life
To ensure your Subaru Forester’s timing chain lasts as long as possible, follow these maintenance tips:
- Regular Oil Changes: Use high-quality oil and change it at the intervals recommended in your owner’s manual. Clean oil reduces friction and wear on the timing chain.
- Listen for Unusual Noises: Pay attention to any rattling or ticking sounds coming from the engine, as these could indicate timing chain issues.
- Address Engine Problems Promptly: If you notice misfires, reduced performance, or a check engine light, have your vehicle inspected by a professional mechanic.
- Follow Manufacturer Guidelines: Stick to Subaru’s recommended maintenance schedule to keep your engine in top condition.
When to Replace the Timing Chain
Although timing chains are designed to last a long time, they may eventually need replacement, especially in high-mileage vehicles. If your Subaru Forester exhibits any of the warning signs mentioned above, it’s crucial to have the timing chain inspected by a qualified mechanic. Ignoring a failing timing chain can lead to severe engine damage, which is far more costly to repair.

Frequently Asked Questions
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.
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.
Can a Subaru timing belt last 200 000 miles?
It is safer to replace the timing belt even earlier than the manufacturer recommends. In general, however, timing belts needs to be replaced from 60,000 miles up to 150,000 miles.
At what mileage should a timing chain be replaced?
between 80,000 and 100,000 miles
When Should It be Replaced? Unless your engine has a specific replacement interval, the commonly accepted mileage is between 80,000 and 100,000 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.
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.
Is it worth fixing a timing chain?
There's no reason to alter the timing chain unless it's damaged, strained, or otherwise affected. If there is a problem with the timing chain, your car will most likely have one or more issues.
When should I replace my timing chain on my Subaru Forester?
For a Subaru Forester, the recommended replacement interval is usually around 105000 miles. However, if you are a gentle driver and maintain your vehicle well, the timing belt might last longer, but it's important to keep an eye on any signs of wear or damage.
How much does it cost to replace a timing belt on a Subaru Forester?
$409 to $919
Shopping around to get a few quotes is your best bet to get the best deal, but you can expect to pay anywhere from $409 to $919 (including parts and labor).
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.
At what mileage should timing chains be replaced?
between 80,000 and 100,000 miles
When Should It be Replaced? Unless your engine has a specific replacement interval, the commonly accepted mileage is between 80,000 and 100,000 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.
