Filling Of Engine Coolant

WARNING: This page is about a different car, the 2006 Subaru Outback. However, it is still accessible from the selected car via links, so may be relevant.
  1. Pour cooling system conditioner through the filler neck.

    Cooling system protective agent: 

    Cooling system conditioner (part number SOA635071) 

  2. Pour engine coolant into the radiator up to the filler neck position.

    Coolant capacity (fill up to "FULL" level): 

    Approx. 7.2 l (7.6 US qt, 6.3 Imp qt) 

    NOTE: The SUBARU Genuine Coolant containing antifreeze and anti-rust agents is especially made for SUBARU engine, which has an aluminum crank-case. Always use SUBARU Genuine Coolant, since other coolant may cause corrosion.
  3. Fill engine coolant into the reservoir tank up to "FULL" level.

  4. Close the radiator cap and start the engine. Race 5 to 6 times at less than 3,000 rpm, then stop the engine. (Complete this operation within 40 seconds.)
  5. Wait for one minute after the engine stops, open the radiator cap. If the engine coolant level drops, add engine coolant into radiator up to the filler neck position.
  6. Perform the procedures 4) and 5) again.
  7. Attach the radiator cap and reservoir tank cap properly.
  8. Start the engine and operate the heater at maximum hot position and the blower speed setting to "LO"
  9. Run the engine at 2,000 rpm or less until radiator fan starts and stops.
    NOTE:
    • Be careful with the engine coolant temperature gauge to prevent overheating.
    • If the radiator hose becomes harden with the pressure of engine coolant, air bleeding operation seems to be almost completed.
  10. Stop the engine and wait until the engine coolant temperature lowers to 30°C (86°F).
  11. Open the radiator cap. If the engine coolant level drops, add engine coolant into radiator up to the filler neck position and reservoir tank to the "FULL" level.
  12. Attach the radiator cap and reservoir tank cap properly.
  13. Set the heater setting to maximum hot position and the blower speed setting to "LO" and start the engine. Perform racing at less than 3,000 rpm. If the flowing sound is heard at this time, perform the procedures from 9) again.
