Does a 2015 Subaru have a timing chain?
Yes, the 2015 Subaru models typically have a timing chain rather than a timing belt. Timing chains are more durable and longer-lasting components compared to timing belts, which need to be replaced periodically as part of regular maintenance.
Timing Chain vs. Timing Belt in Subaru Vehicles
Subaru engines, including those found in the 2015 model year, utilize a timing chain to synchronize the opening and closing of the engine's valves with the rotation of the crankshaft. Timing chains are metal components that are designed to last the lifetime of the engine, whereas timing belts are made of rubber and need to be replaced every 60,000 to 100,000 miles, depending on the manufacturer's recommendations.
The use of a timing chain in Subaru vehicles provides several advantages over a timing belt:
- Durability: Timing chains are more resistant to wear and tear compared to timing belts, which can stretch, crack, or break over time.
- Longevity: Timing chains typically last the entire lifespan of the engine, eliminating the need for periodic replacement.
- Reliability: The failure of a timing belt can cause significant engine damage, but a timing chain is less likely to fail unexpectedly.
While timing chains are generally more expensive to manufacture, the long-term cost savings and improved reliability make them a preferred choice for Subaru's engine designs.
Subaru Engines with Timing Chains
The majority of Subaru's engine offerings, including the popular Boxer engines found in models like the Outback, Ascent, and Impreza, utilize a timing chain system. This includes the following Subaru engines from the 2015 model year:
- 2.5L Boxer 4-cylinder engine
- 3.6L Boxer 6-cylinder engine
- 2.4L Turbo Boxer 4-cylinder engine
By using a timing chain in these engines, Subaru has been able to provide drivers with a more durable and reliable powertrain that requires less maintenance over the life of the vehicle.
