Cooling System

11-7. Cooling 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
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.
Should it be 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 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-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to "Engine Coolant Tem-
perature Gauge" FP175.
Check the fuse and replace it if necessary.
Refer to "Fuses" FP517 and "Fuses and
Circuits" FP538. If the fuse is not blown,
have the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is necessary,
there may be a leak in the engine cooling
system. It is recommended that the cooling
system and connections be checked for
leaks, damage, or looseness.
