Does Subaru have a belt or chain?
Subaru vehicles typically use a timing chain rather than a timing belt. The timing chain is a more durable and long-lasting component that is designed to last the lifetime of the engine, unlike a timing belt which may need to be replaced periodically.
Timing Chain vs. Timing Belt
The timing system in an engine is responsible for precisely coordinating the opening and closing of the intake and exhaust valves with the movement of the pistons. This is typically done using either a timing chain or a timing belt.
- Timing Chain: A timing chain is a metal chain that connects the crankshaft to the camshaft, allowing them to rotate in sync. Timing chains are generally more durable and longer-lasting than timing belts, often lasting the entire lifespan of the engine.
- Timing Belt: A timing belt is a toothed rubber belt that performs the same function as a timing chain. Timing belts typically need to be replaced every 60,000 to 100,000 miles as they can wear out over time.
Subaru has historically used timing chains in the majority of its engines, as the chain design is better suited to the company's focus on reliability and longevity.
Subaru Timing Chain Advantages
There are several key advantages to Subaru's use of timing chains:
- Longer Lifespan: Timing chains can last the entire lifetime of the engine, whereas timing belts typically need replacement every 60,000 to 100,000 miles. This reduces maintenance costs for Subaru owners.
- Improved Reliability: Timing chains are less prone to failure than timing belts, which can break unexpectedly and cause significant engine damage.
- Better Performance: Timing chains are more precise in their operation, allowing for tighter tolerances and better engine performance.
Overall, Subaru's use of timing chains in its engines is a key factor in the brand's reputation for reliability and longevity.
When did Subaru change from timing belt to chain?
FB engine (timing chain, among other changes) started in 2011 Foresters, 2012 Imprezas, and 2013 Legacy/Outbacks. All EZ 6-cylinders (3.0 and 3.6, since 2001) had timing chains.
Do Subarus have a serpentine belt?
Subaru Serpentine Belt Replacement in Centennial
This single belt is driven by the crankshaft pulley and winds its way around to each accessory. While the serpentine belt is a very sturdy component that can generally last 50,000 miles or more, it will still wear over time and start to slip.
What years did Subaru have CVT transmission problems?
Subaru Legacy: 2010-2015 Models
The Subaru Legacy shares many of its components with the Outback. Thus, it's no surprise that similar model years—2010 to 2015—have similar issues. The CVT transmission problems were also among the most prominent.
Is Subaru CVT belt or chain?
After trying to improve this process, Subaru engineers developed the Lineartronic CVT transmission. This CVT transmission, mounted longitudinally with a Subaru All-Wheel Drive, chain rather than a belt.
Does the Subaru Boxer engine have a timing belt or chain?
Today, many Subaru BOXER® engines are equipped with a timing chain that should not require any maintenance.
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 will a Subaru boxer engine last?
200,000 miles
Subaru vehicles are renowned for their exceptional longevity, often surpassing 200,000 miles or more with proper maintenance and care.
Do subarus have timing belts or chains?
Simply, then, a 1997 to 2011 Forester will have a timing belt, while any of the fourth-gen Foresters (from 2013 or later) will have a timing chain. And for a brief period from 2011 to 2012, the Forester was fitted with either a timing belt or a timing chain depending on which engine was fitted.
Do Subarus use chains?
The simple answer: no. Due to Subaru's Symmetrical All-Wheel Drive system, adding snow chains to your tires is not necessary, nor recommended. Many of Subaru's vehicle manuals explicitly state that snow chains are not recommended.
