radiator cap SUBARU OUTBACK 2016 6.G Owners Manual

Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place.
&If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
&If no steam is coming from
the engine compartment
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-14.
1. Keep the engine running at idling
speed.2. Open the hood to ventilate the engine
compartment. Refer to“Engine hood”
F11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Towing
WARNING
Never tow AWD vehicles with the
front wheels raised off the ground
while the rear wheels are on the
ground, or with the rear wheels
raised off the ground while the front
wheels are on the ground. This will
cause the vehicle to spin away due
to the operation or deterioration of
the center differential.
If towing is necessary, SUBARU recom-
mends it be done by your SUBARU dealer
or a commercial towing service.

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.
