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 — 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.
