What year did Subaru go to timing chain?
Subaru, the renowned Japanese automaker, made a significant shift in its engine design by transitioning from a timing belt to a timing chain in the mid-2000s. This change marked a pivotal moment in the company's history, as it aimed to enhance the reliability and longevity of its vehicles.
The Timing Belt Era
Prior to the mid-2000s, Subaru engines were equipped with a timing belt, a component responsible for synchronizing the rotation of the crankshaft and camshaft. Timing belts were a common feature in many automotive engines, as they were relatively inexpensive to manufacture and easy to install. However, they had a limited lifespan and required periodic replacement, typically every 60,000 to 100,000 miles, to prevent potential engine damage.
The Shift to Timing Chain
In the mid-2000s, Subaru made the strategic decision to transition its engine design from a timing belt to a timing chain. Timing chains are more durable and longer-lasting components compared to timing belts, often lasting the entire lifetime of the engine. This change was driven by Subaru's commitment to improving the reliability and longevity of its vehicles, as well as addressing the inconvenience and potential costs associated with regular timing belt replacements.
Benefits of the Timing Chain
- Increased Reliability: Timing chains are less prone to wear and tear, reducing the risk of unexpected failures and engine damage.
- Reduced Maintenance Costs: With a timing chain, Subaru owners no longer need to budget for periodic timing belt replacements, saving them money in the long run.
- Improved Durability: Timing chains are designed to withstand the rigors of high-mileage driving, providing a more robust and long-lasting solution for Subaru's engines.
The transition to a timing chain was a strategic move by Subaru to enhance the overall quality and ownership experience of its vehicles. By prioritizing reliability and reducing maintenance requirements, Subaru aimed to build a stronger reputation for producing dependable and low-cost-of-ownership automobiles.
In summary, Subaru's shift to a timing chain in the mid-2000s was a significant milestone in the company's engineering history, reflecting its commitment to improving the longevity and reliability of its vehicles. This change has had a lasting impact on Subaru's reputation and the ownership experience of its loyal customers.
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 year did Subarus have bad head gaskets?
The Subaru Head Gasket Problem
A number of Subaru models are affected, however the most common failures include the 2.5 Liter SOHC engine used in the late 1999-2004, Forester, Impreza, Outback and Legacy. Signs and symptoms of engine head gasket failure include: Engine overheating.
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.
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.
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 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.
When did Subaru go 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.
What is the biggest problem with Subaru engines?
One of the most notorious issues plaguing Subaru vehicles is head gasket leaks, particularly in older models with the EJ series engines. These leaks can lead to coolant loss, overheating, and potential engine damage if left untreated.
What Subaru models have a timing chain?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
What year did Subaru have engine problems?
Subaru WRX and WRX STI: 2008-2014 Models
The performance-oriented Subaru WRX and WRX STI from 2008 to 2014 unfortunately did not escape their own set of difficulties. These cars were plagued with engine problems.
