Maintenance and service/Cooling system
Cooling system
WARNING
Never attempt to remove the radia-
tor 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 boil-
ing 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. Should it be
necessary to top off the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand ortype, 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.
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“Temperature gauge”
F3-11.
Check the fuse and replace it if necessary.
Refer to“Fuses”F11-38 and“Fuses and
circuits”F12-10. If the fuse is not blown,
have the cooling system checked by your
SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections bechecked for leaks, damage, or looseness.
&Engine coolant
!Checking the coolant level
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
as required.
3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.

&Engine oil
For the checking, adding and replacing procedure or other details, refer to“Engine oil”F11-11.
NOTEThe procedure for changing the engine oil and oil filter should be performed by a properly-trained expert. It is recommended
that you have this service performed by your SUBARU dealer.
!Approved engine oil
Always use the SUBARU approved engine oil. For further details, please contact your SUBARU dealer.
If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
!Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.
NOTE
.Each quantity indicated is only a guideline. The necessary quantity for replacement may differ slightly depending on the
temperature and other factors.
.In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommended viscosities and applicable temperatures.
.When adding oil, different brands may be used together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.
