Does a 2006 Subaru Forester have a timing belt?

The 2006 Forester, part of Subaru’s second-generation lineup, uses a timing belt on its 2.5-liter four‑cylinder engine. The belt‑driven timing system is a critical maintenance item that should be replaced on schedule to avoid costly engine damage. The turbocharged XT variant in the same year also relies on a belt-driven setup.

Engine basics and timing belt configuration

Most 2006 Forester models are powered by the 2.5-liter horizontally opposed (boxer) engine from the EJ25 family. All of these engines use a timing belt rather than a chain to synchronize the camshafts with the crankshaft. This is an interference design, so belt failure can damage valves and pistons.

Key facts about the timing belt in this generation

Here are essential points about how the belt operates in the 2006 Forester and what owners should expect during maintenance.

• Belt-driven camshafts: The EJ25 2.5L Boxer engine uses a timing belt to synchronize valve timing; there is no timing chain in these models.


• Interference engine risk: If the belt breaks or slips, valve-to-piston contact can occur, causing expensive damage.


• All-year variant coverage: Both naturally aspirated and turbocharged 2.5L versions of the 2006 Forester rely on a timing belt.


• Replacement interval: Official guidance is typically around 105,000 miles (about 169,000 km) or 8 years, whichever comes first, though owners should confirm via the vehicle’s manual.

These points establish why adherence to the service interval is important for longevity and reliability.

Maintenance intervals and components to replace

To prevent unexpected belt failure, owners should follow Subaru's recommended service interval and consider replacing ancillary components at the same time.

Important details about what to replace and when:

• Timing belt kit: Includes the belt itself along with tensioner and idlers; these parts wear alongside the belt and are routinely replaced together.


• Water pump replacement: Since the water pump is driven by the timing belt on many Subaru engines, it is common practice to replace the water pump during a belt job to avoid additional labor costs later.


• Auxiliary components: Some mechanics also inspect the serpentine belt and replace if cracked or worn, though it is not always bundled in the belt kit.


• Interval cadence: Replacement is typically specified at about 105,000 miles (169,000 km) or 8 years, whichever comes first; a dealer or trusted shop can confirm the exact figure for your vehicle's VIN.

Following this maintenance approach minimizes the risk of belt failure and protects the engine's integrity.

Signs of timing belt wear or impending failure

Be alert to indicators that the belt may be nearing the end of its service life or has slipped or failed.

Common warning signs to watch for:

• Cracked, frayed, or glazed belt edges; visible wear on the belt surface


• Squealing or chirping noises from the engine area, often indicating a worn tensioner or belt slippage


• Rough idle, misfires, or engine timing-related performance problems


• Oil or coolant leaks near the front of the engine, which can affect belt condition

If any of these signs are observed, have the timing belt and related components inspected promptly by a qualified mechanic to avoid catastrophic engine damage.

Summary

Bottom line: yes, a 2006 Subaru Forester uses a timing belt for its 2.5-liter engine. Plan for a belt replacement around 105,000 miles (roughly 169,000 kilometers) or about 8 years, replace the belt with tensioners/idlers (and often the water pump), and stay alert for wear signs to protect the engine from damage.

What year to stay away from a Subaru Forester?

You should generally stay away from Subaru Forester model years known for significant engine issues, such as the 1998–2001, 2003, 2006, 2009, and 2010 models due to head gasket failures and other problems. The 2011–2014 and 2014–2018 models are also problematic, particularly for excessive oil consumption, CVT transmission issues, and suspension problems, according to sources like Panda Hub, CoPilot for Car Shopping, CarBuzz, and MotorBiscuit.
