2022 Subaru Outback productCooling System

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.

CAUTION

  • Vehicles are filled at the factory with SUBARU SUPER COOLANT which does not require the first change for 11 years/137,500 miles (11 years/220,000 km). This coolant should not be mixed with any other brand or type of coolant during this period. Mixing with a different coolant will reduce the life of the coolant. When necessary to top off the coolant for any reason, use only SUBARU SUPER COOLANT.
    • If SUBARU SUPER COOLANT is diluted with another brand or type, the maintenance interval is shortened to that of the mixing coolant.
  • Do not splash the engine coolant over painted parts. The alcohol contained in the engine coolant may damage the paint surface.

Cooling Fan, Hose, and Connections

  • Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature2022 Subaru Outback Cooling System FIG 17
  • If the radiator cooling fan does not operate even when the engine coolant temperature gauge exceeds the normal operating range, the cooling fan circuit may be defective. Refer to “Engine Coolant Temperature Gauge” P177.
  • Check the fuse and replace it if necessary. If the fuse is not blown, have the cooling system checked by your SUBARU dealer.
  • If the frequent addition of coolant is necessary between vehicle service visits, it is recommended that you have your vehicle inspected by an authorized SUBARU dealer to check for leaks, damage, or looseness.

Engine Coolant

Checking the coolant level2022 Subaru Outback Cooling System FIG 18

  1. “FULL” level mark
  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 the coolant up to just below the filler neck as shown in the following illustration2022 Subaru Outback Cooling System FIG 19
  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 position2022 Subaru Outback Cooling System FIG 20

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. Has the coolant been changed by your Subaru dealer if necessary? The coolant should be changed according to the maintenance schedule in the “Warranty and Maintenance Booklet.”
