& Safety precautions
WARNING
S11AF
S11AF04
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.
& Cooling fan, hose and connections
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” FP168.
Check the fuse and replace it if necessary. Refer to“ Fuses” FP506.
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.
