Never 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 that 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 add up 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 .

S11AF03
Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature .
1 Normal operating range
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 ” FP170 .
Check the fuse and replace it if necessary . Refer to “ Fuses ” FP510 .
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 .
