What year did Subaru use a timing chain?
As a seasoned auto service provider, I often get questions about the intricacies of vehicle maintenance, including the components that keep engines running smoothly. One common inquiry revolves around the timing chain used in Subaru vehicles. In this article, we'll explore when Subaru transitioned to timing chains and the implications for car owners.
What is a Timing Chain?
A timing chain is a crucial component in an engine that synchronizes the rotation of the crankshaft and camshaft. Unlike timing belts, which are made of rubber and require regular replacement, timing chains are typically more durable and designed to last the lifetime of the engine. However, they can still wear out and require replacement under certain conditions.
Subaru's Use of Timing Chains
Subaru began using timing chains in several of their models starting in the early 2000s. Specifically, the following models are known for utilizing timing chains:
- Subaru Legacy (2005 and newer)
- Subaru Outback (2005 and newer)
- Subaru Impreza (2008 and newer)
- Subaru Forester (2009 and newer)
Prior to this shift, many Subaru models were equipped with timing belts, which required more frequent maintenance. The transition to timing chains was part of Subaru's effort to enhance engine reliability and reduce maintenance costs for owners.
Benefits of Timing Chains
There are several advantages to having a timing chain in your Subaru:
- Durability: Timing chains are generally more robust than belts and can last much longer, often exceeding 100,000 miles.
- Less Maintenance: Unlike timing belts, which need to be replaced at regular intervals, timing chains typically do not require replacement unless there is a specific issue.
- Performance: Timing chains can provide better performance due to their ability to maintain precise timing under various engine conditions.
Conclusion
Understanding the components of your vehicle is essential for effective maintenance and longevity. If you own a Subaru model from 2005 or later, you can rest assured that your vehicle is equipped with a timing chain, which offers several benefits over traditional timing belts. Regular maintenance and timely inspections will help ensure that your engine continues to perform at its best.
Frequently Asked Questions
What year did Subaru fix the head gasket issue?
Subaru was quick to come up with an updated version of the head gaskets. Thicker and with more layers these updates MLS gaskets fixed the problems that plagued the DOHC 2.5l produced from 1995-1999 in the Subaru Legacy, Legacy Outback, Legacy GT, Impreza RS and the Subaru Forester in 1998.
What are the symptoms of a bad timing chain?
Misfiring, poor idle, and rough running could mean the chain has jumped a tooth and the timing is off. Replacement is urgent, because the chain could break at any point, and the engine could be damaged from incorrect valve timing.
How do I know if my Subaru has a timing belt or chain?
Cars with a timing belt have a plastic cover near the engine block (often to the left-hand side), which provides easy access to the belt. It needs changing at regular intervals, which is why the removable cover is necessary. In cars with a timing chain, you won't see a plastic cover.
What is the life expectancy of a Subaru CVT transmission?
There is a fair chance your Subaru CVT will last well beyond 60,000 miles as long as you stick to the factory-recommended maintenance schedule and take care not to overfill your transmission fluid.
Which Subaru does not use CVT?
Subaru BRZ
Since 2014, the Lineartronic® CVT has been standard in all automatic Subaru models and trims (except the Subaru BRZ).
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.
How long does a Subaru timing chain last?
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.
What Subaru models have a timing chain?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
What years did Subaru have CVT problems?
The models and years that were affected mainly by transmission issues are:
- Crosstrek, 2013 – 2015.
- Crosstrek Hybrid, 2014 – 2015.
- Forester (2.0 and 2.5 liter engines), 2014 – 2015.
- Impreza, 2012 – 2015.
- Legacy, 2010 – 2015.
- Legacy 3.6L V6, 2015.
- Outback, 2010 – 2015.
- Outback 3.6L V6, 2015.
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.
