Subaru Forester: Cooling system / Engine coolant

Checking the coolant level

WARNING

Never attempt to remove the radiator cap until the engine has been shut off and has cooled down completely. Since the coolant is under pressure, you may suffer serious burns from a spray of boiling hot coolant when the cap is removed.

  2. “LOW” level mark

Check the coolant level at each fuel stop.

  1. Check the coolant level on the outside of the reservoir while the engine is cool.
  2. If the level is close to or lower than the “LOW” level mark, add coolant up to the “FULL” level mark. If the reserve tank is empty, remove the radiator cap and refill coolant up to just below the filler neck as shown in the following illustration.

  3. After refilling the reserve tank and the radiator, reinstall the cap and check that the rubber gaskets inside the radiator cap are in the proper position.

CAUTION

  • Be careful not to spill engine coolant when adding it. If coolant touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. If engine coolant gets on the exhaust pipe, be sure to wipe it off.
  • Do not splash the engine coolant over painted parts. The alcohol contained in the engine coolant may damage the paint surface.

Changing the coolant

It may be difficult to change the coolant. Have the coolant changed by your SUBARU dealer if necessary.

The coolant should be changed according to the maintenance schedule in the “Warranty and Maintenance Booklet”.
