Do Subaru timing chains need to be replaced?
The short answer is that Subaru timing chains generally do not need to be replaced as part of regular maintenance, unlike timing belts which require periodic replacement. However, there are some important considerations regarding Subaru timing chains that owners should be aware of.
Understanding Subaru Timing Chains
Subaru engines use timing chains rather than timing belts to synchronize the opening and closing of the engine's valves with the movement of the pistons. Timing chains are designed to last the lifetime of the engine, unlike timing belts which need replacement every 60,000 to 100,000 miles. Subaru timing chains are typically very durable and reliable, with many owners reporting no issues even after 200,000 miles or more of use.
When Subaru Timing Chains May Need Replacement
While Subaru timing chains are long-lasting, there are a few situations where they may need to be replaced:
- Excessive Wear or Stretching: Over many years of use, the timing chain can experience some wear and stretching, which can eventually cause it to slip and fall out of proper timing. This is more likely to occur in high-mileage engines.
- Timing Chain Tensioner Failure: The timing chain tensioner is responsible for maintaining the proper tension on the chain. If the tensioner fails, the chain can become loose and cause timing issues.
- Engine Damage: Significant engine damage, such as from a collision or severe overheating, can also potentially damage the timing chain and require replacement.
In these cases, a Subaru timing chain replacement may be necessary to restore proper engine operation and prevent further damage.
Recommended Maintenance
While Subaru timing chains generally do not require scheduled replacement, it is still important to have the timing chain system inspected periodically as part of regular maintenance. This allows any potential issues to be identified and addressed before they lead to more serious problems. Subaru recommends having the timing chain system inspected every 60,000 miles or so.
In summary, Subaru timing chains are designed to last the lifetime of the engine and typically do not need to be replaced as part of regular maintenance. However, owners should be aware of potential issues that may require timing chain replacement, and have the system inspected regularly as part of their Subaru's preventative maintenance routine.
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!
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.
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.
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!
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.
Which Subaru models have timing chains?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
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 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.
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.
