Buying Tips for 2001–2002 Subaru Forester Mk1 (SF)

  • ✓The 2.0L non-turbo engine is arguably Subaru’s most robust unit if the cambelt and oil are changed regularly.
  • ✓Check the radiator top tank for cracks; a failure here usually leads to immediate engine overheating.
  • ✓Inspect the rear strut towers from inside the boot; rot here is a common but hidden killer of SF Foresters.
