Does the Subaru Ascent have a timing chain?
The Subaru Ascent, a popular midsize SUV known for its spacious interior and all-wheel-drive capability, is a reliable choice for families and adventurers alike. One common question among Subaru Ascent owners and potential buyers is whether this vehicle is equipped with a timing chain or a timing belt. Understanding this distinction is crucial for maintenance planning and long-term ownership costs.
Timing Chain vs. Timing Belt: What’s the Difference?
Before diving into the specifics of the Subaru Ascent, it’s important to understand the difference between a timing chain and a timing belt. Both components serve the same purpose: they synchronize the rotation of the engine’s crankshaft and camshaft, ensuring that the engine’s valves open and close at the right times during each cylinder’s intake and exhaust strokes. However, there are key differences:
- Timing Belt: Made of rubber and reinforced with materials like fiberglass or Kevlar, timing belts are lighter and quieter but require periodic replacement, typically every 60,000 to 100,000 miles.
- Timing Chain: Made of metal, timing chains are more durable and designed to last the lifetime of the engine. They require less frequent maintenance but can be noisier and more expensive to replace if they fail.
Does the Subaru Ascent Use a Timing Chain?
The Subaru Ascent is equipped with a timing chain rather than a timing belt. This is consistent with Subaru’s engineering approach in recent years, as most of their modern engines, including the 2.4L turbocharged BOXER engine found in the Ascent, utilize timing chains. This design choice enhances durability and reduces the need for regular replacement, which can save owners money on maintenance over the life of the vehicle.
Benefits of a Timing Chain in the Subaru Ascent
There are several advantages to having a timing chain in your Subaru Ascent:
- Longevity: Timing chains are built to last the lifetime of the engine, reducing the need for costly replacements.
- Reliability: Metal chains are less prone to wear and tear compared to rubber belts, making them more reliable over time.
- Lower Maintenance Costs: While timing chains may require occasional inspection and lubrication, they do not need to be replaced at regular intervals like timing belts.
Maintenance Tips for Timing Chains
Although timing chains are durable, they still require some care to ensure optimal performance. Here are a few tips:
- Follow the manufacturer’s recommended maintenance schedule for oil changes, as clean oil is essential for lubricating the timing chain.
- Listen for unusual noises, such as rattling, which could indicate a problem with the timing chain or its tensioner.
- Have your mechanic inspect the timing chain during routine maintenance to catch any potential issues early.
Conclusion
The Subaru Ascent’s use of a timing chain is a testament to its focus on durability and long-term reliability. For owners, this means fewer maintenance concerns and greater peace of mind. By following proper maintenance practices, you can ensure that your Ascent’s timing chain continues to perform flawlessly for years to come.
Frequently Asked Questions
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.
Why is the Subaru Ascent rated so low?
Lows Sluggish acceleration, noisy engine, not as spacious as rivals. Verdict The Ascent is a respectable choice as a rugged, go-anywhere family vehicle, but it lags behind in driving feel and performance.
What are the weaknesses of the Subaru Ascent?
A list of some of the most common issues Ascent owners have to deal with.
- Denso Fuel Pump Failure. The impellers inside of Denso branded fuel pumps may have been excessively exposed to a drying agent during manufacturing.
- CAN System Parasitic Drain on the Battery.
- Cracked Windshields.
- Subaru EyeSight Problems.
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 years did Subaru have CVT problems?
Subaru owners have complained about problems with the Lineartronic CVT transmissions and Subaru extended the warranty for cars from model years 2010 to 2018.
Which Subaru models have timing chains?
All Foresters from 2011 onward (2014 for the XT) have a timing chain.
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.
Do Subaru Ascents have a timing belt or chain?
Guide for the timing chain. Your engine's timing chain can stretch over time resulting in a check engine light that comes along with excessive noise from your engine's timing cover. If the chain has broken, which is a rare occurrence, the engine will not start.
Which engines have timing chains?
Vehicles that have a timing chain instead of a cambelt include:
- Most BMWs.
- Dacia Sandero (TCe engine)
- Suzuki Swift.
- Most MINIs.
- Most Audi petrol models.
- Toyota Yaris.
- Honda Jazz.
Why did they stop using timing chains?
For some time now, vehicle manufacturers have been moving away from chains again because the friction loss with chains is too great.
