Subaru Outback 2005–2009 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes, not generic used-car advice.

1. Check 01

   Cold engine, on a lift or with a flashlight: inspect the head-gasket seam on both sides of the EJ253 block for coolant crust or oil weep. The leak is external and visible before it's terminal.

2. Check 02

   Ask directly for head-gasket receipts. 'Done with updated Subaru MLS gaskets + timing belt + water pump' is the answer you want on any 2.5i over ~100k miles.

3. Check 03

   Drive full-lock circles in a parking lot both directions. Any shudder, hop, or binding on an automatic = torque bind, budget $700–$1,800.

4. Check 04

   Listen for a highway hum that changes with gentle lane weaves, the classic worn wheel bearing on this generation.

5. Check 05

   On a 2.5XT: demand oil-change records and ask whether the turbo oil-supply banjo-bolt screen was serviced or removed. No records on a 2005–2006 XT is a walk-away.

6. Check 06

   Check for a stored or recent P0420 code with a scanner. A tired catalytic converter or rear O2 sensor is common and matters in emissions states.

7. Check 07

   Verify the Takata passenger-airbag recall was completed by VIN (free at a Subaru dealer or nhtsa.gov).

8. Check 08

   On the 3.0R, look under the timing cover area at the front of the engine for oil seepage dripping onto the undertray.
