11-6. Cooling system

& Safety precautions
WARNING
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 cool-
ant during this period. Mixing
with a different coolant will re-
duce 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 con-
nections
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 tempera-
Cooling system
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to "Engine coolant tem-
perature gauge" �P170.
Check the fuse and replace it if necessary.
Refer to "Fuses" �P510.
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, da-
mage, or looseness.
