Alton Brobst If you’re in the market for a Subaru or own one, you may be wondering what year Subaru switched to timing chains. The timing chain is a vital component of the engine that helps keep everything running smoothly. In this article, we’ll explore the history of Subaru’s use of timing chains and answer the question of when they made the switch.
Key Takeaways
- Subaru switched to timing chains in 2013 with the introduction of the FB engine.
- Timing chains are generally more durable and longer-lasting than timing belts.
- Regular maintenance is still required for timing chains to ensure proper operation.
Subaru’s History With Timing Components
Subaru has a long history of using timing belts in their engines. Timing belts are made of rubber and can wear out over time, which can lead to engine damage if they break. Subaru’s older engines were equipped with timing belts, which required replacement every 60,000 to 100,000 miles.
However, in recent years, Subaru has started to switch to timing chains. Timing chains are made of metal and are generally more durable than timing belts. They don’t require the same regular replacement as timing belts do.
When Did Subaru Switch to Timing Chains?
Subaru made the switch to timing chains in 2013 with the introduction of the FB engine. The FB engine was first used in the 2013 Forester and has since been used in other Subaru models, including the Impreza, Legacy, and Outback.
The FB engine is a newer engine design that includes a timing chain instead of a timing belt. This change was made to improve the durability and longevity of the engine. The timing chain in the FB engine is designed to last the life of the engine, so it doesn’t require regular replacement like timing belts do.
It’s worth noting that just because an engine has a timing chain doesn’t mean it’s maintenance-free. Regular maintenance is still required to ensure the timing chain is functioning properly. If the timing chain stretches or wears out, it can still cause engine damage.
Advantages of Timing Chains
There are several advantages to using a timing chain in an engine. Here are a few of the most significant benefits:
- Durability: Timing chains are made of metal and are generally more durable than timing belts. They are less likely to break or wear out over time.
- Longer lifespan: Timing chains are designed to last the life of the engine, so they don’t require regular replacement like timing belts do.
- Less maintenance: Because timing chains don’t require regular replacement, they require less maintenance overall.
- Better performance: Timing chains are generally more precise than timing belts, which can lead to better engine performance.
Frequently Asked Questions
How often do timing chains need to be replaced?
Timing chains are generally designed to last the life of the engine and don’t require regular replacement like timing belts do. However, regular maintenance is still required to ensure the timing chain is functioning properly.
What happens if a timing chain breaks?
If a timing chain breaks, it can cause significant damage to the engine. The valves and pistons in the engine can collide, causing bent valves, damaged cylinder heads, and other problems.
Do all Subaru engines have timing chains?
No, not all Subaru engines have timing chains. Older Subaru engines were equipped with timing belts, which required replacement every 60,000 to 100,000 miles.
Is a timing chain better than a timing belt?
Timing chains are generally considered to be better than timing belts. They are more durable and longer-lasting, which means they don’t require regular replacement like timing belts do.
Conclusion
Subaru made the switch to timing chains in 2013 with the introduction of the FB engine. Timing chains are generally more durable and longer-lasting than timing belts, which is why they are becoming more common in modern engines. If you’re in the market for a Subaru or own one, it’s worth noting whether it has a timing chain or a timing belt and understanding the maintenance requirements to keep it running smoothly. Regular maintenance is still required for timing chains to ensure proper operation.
