How long do Subaru timing chains last?

Subaru Timing Chains Lifespan
Subaru timing chains are designed to last the entire lifetime of the engine. Unlike timing belts, which require periodic replacement, timing chains, being made of sturdy metal, generally do not need to be replaced unless they break [[4]]. This is a significant advantage as it eliminates the need for regular maintenance associated with timing belt replacements and can contribute to better engine life with regular maintenance.
Subaru Models with Timing Chains
The timing system in Subaru vehicles varies based on the model and year. Here’s a breakdown of the timing systems in different Subaru models:
– Subaru Forester: The Forester models from 2011 and later are equipped with a timing chain, while earlier models feature a timing belt.
– Subaru Outback: The 4-cylinder engines in the Outback from 2013 to 2024 have timing chains, while the 6-cylinder engines from 2001 to 2019 also have timing chains [[10]].
It’s important to note that all Subaru Outback engines are interference engines, which means that if the timing belt or chain stretches or breaks, it can lead to catastrophic engine damage .
In summary, Subaru timing chains are designed to last the entire lifetime of the engine and generally do not need to be replaced unless they break. The specific type of timing mechanism used in a Subaru engine can depend on the model and year, with newer models typically featuring timing chains [[4]] [[10]].
