When did Subaru switch from timing belt to chain?
Subaru, the renowned Japanese automaker, has gradually transitioned its engine designs from using timing belts to timing chains over the past few decades. This shift has had significant implications for the maintenance and reliability of Subaru vehicles.
The Timing Belt Era
Historically, Subaru engines were equipped with timing belts, which are responsible for synchronizing the opening and closing of the engine's valves. Timing belts require periodic replacement, typically every 60,000 to 105,000 miles, depending on the specific model and driving conditions. Failure to replace the timing belt at the recommended interval can lead to catastrophic engine damage, as the belt may break and cause the pistons to collide with the valves.
The Shift to Timing Chains
In recent years, Subaru has been phasing out the use of timing belts in favor of timing chains. Timing chains are more durable and generally do not require scheduled replacement, as they are designed to last the lifetime of the engine. This transition has provided several benefits for Subaru owners:
- Reduced Maintenance Costs: With no need for periodic timing belt replacement, Subaru owners can save on the associated labor and parts costs.
- Improved Reliability: Timing chains are less prone to failure than timing belts, reducing the risk of catastrophic engine damage.
- Longer Engine Life: The longevity of timing chains can contribute to the overall lifespan of Subaru engines.
The transition to timing chains has been gradual, with Subaru phasing it in across its model lineup over the past decade or so. Many of Subaru's current models, such as the Outback, Ascent, and Impreza, now feature timing chain-equipped engines.
Identifying Subaru Models with Timing Chains
To determine if a specific Subaru model has a timing chain or timing belt, it's best to consult the owner's manual or contact a Subaru dealer. Some general guidelines:
- Newer Subaru models (2015 and later) are more likely to have timing chains.
- Subaru's turbocharged engines, such as those found in the WRX and STI models, often use timing chains.
- Subaru's larger displacement engines, like the 2.4-liter and 2.5-liter flat-four engines, are more likely to have timing chains.
By understanding Subaru's transition from timing belts to timing chains, Subaru owners can better plan for their vehicle's maintenance needs and enjoy the benefits of this more reliable engine design.
What year did Subaru change to timing chains?
Subaru engines used belts , except for the boxer ez. 3.6 and diesel engines until about 2011. 2012-up 4th generation Subaru used chains and on newer engines.
Which Subaru models have timing chains?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
Is a timing belt better than a timing chain?
Though it's certainly a matter of opinion that's based largely on your priorities, it's generally felt that timing chains are better than timing belts. While most timing belts are supposed to be replaced every 60,000 to 120,000 miles, many timing chains end up lasting the life of the car.
Does a 2012 Subaru have a timing belt or chain?
For example, the engine in the 2012 Subaru Outback features a timing belt. According to the manufacturer's recommended maintenance schedule, this timing belt should be regularly inspected every 30,000 miles.
What year did Subaru switch to CVT?
2014
For example, for the 2014 Forester, Subaru introduced a CVT. With the same engine as the previous generation, the new Forester gets FIVE (!) more mile per gallon. The CVT finds the most fuel efficient point in the engine power band and keeps it there.
Which Subaru models have no CVT?
Since 2014, the Lineartronic® CVT has been standard in all automatic Subaru models and trims (except the Subaru BRZ).
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 Subaru fix the head gasket issue?
2009
Subaru used in production the updated version of the head gasket which again solved nothing up until 2009 in the Legacy and Outback. 2011 in the Impreza and 2010 in the Forester. Here is where the next few years get very complicated.
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.
What year does Subaru have a bad CVT?
Several older models have experienced Subaru CVT problems – enough so that Subaru has offered factory warranty extensions on these vehicles. Affected models include: 2010-2015 Legacy. 2010-2015 Outback.
