engine coolant SUBARU FORESTER 2013 SH / 3.G User Guide

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, safely pull off the
road 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 ”F 11-14.
1. Keep the engine running at idlingspeed. 2. Open the hood to ventilate the engine
compartment. Refer to
“Engine hood ”
F 11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your SUBARU
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If any of the following conditions occur,
turn off the engine. .The temperature gauge stays in the
overheated zone (if equipped). Referto “Temperature gauge (models with
type A combination meter) ”F 3-11.
. The coolant temperature high warn-
ing light remains illuminated (if
equipped). Refer to “Coolant tempera-
ture low indicator light/Coolant tem-
perature high warning light ”F 3-16.
4. After the engine has fully cooled down,
check the coolant level in the reservoir.
If the coolant level is below the “LOW ”
mark, add coolant up to the “FULL ”mark.
5. If there is no coolant in the reservoir,
add coolant to the reservoir. Then remove
the radiator cap (non-turbo models) or the
coolant filler tank cap (turbo models) and
fill the radiator with coolant.
If you have to remove a hot radiator cap/
coolant filler tank cap, first wrap a thick cloth around the cap, then turn the cap
counterclockwise slowly without pressing
down until it stops. Release the pressure
from the cooling system. After the pres-
sure has been fully released, remove the
cap by pressing it down and turningcounterclockwise.

11-4Maintenance and service
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for this wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer. &
Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and apply
the parking brake firmly to pre-
vent the vehicle from moving.
. Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after
the engine is stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. Always remove the key from the
ignition switch. When the ignition
switch is in the “ON ”position,
thecoolingfanmayoperate
suddenly even when the engine
is stopped.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system (a
dealer option) temporarily place
that system in the service mode
to prevent it from unexpectedly
starting the engine. &
When checking or servicing
in the engine compartment
(non-turbo models)
CAUTION
. Do not contact the belt cover
while checking the components
in the engine compartment.
Doing so may cause your hand
to slip off the belt cover and
result in an unexpected injury.
. Do not touch the oil filter until the
engine has cooled down comple-
tely. Doing so may result in a
burn or other injury. Note that the
oil filter becomes very hot when
the engine is running and re-
mains hot for some time after

&Recommended grade and viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to “Engine oil ”F 12-5.
NOTE
Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-gine. & Synthetic oil
You should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner ’s Manual. Refer to “Engine
oil ”F 12-5. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet. NOTE
Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom- mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
Cooling systemWARNING
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 isremoved.
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 up the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is Maintenance and service
11-13
– CONTINUED –

11-14Maintenance and service
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 following conditions occur,
the cooling fan circuit may be defective. . The engine coolant temperature gauge
exceeds the normal operating range (if
equipped). Refer to “Temperature gauge
(models with type A combination meter) ”
F 3-11.
. The coolant temperature high warning
light blinks or illuminates in RED(if
equipped). Refer to “Coolant temperature
low indicator light/Coolant temperature
high warning light ”F 3-16.
Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer. Refer to
“Fuses ”F 11-44 and “Fuse panel
located in the engine compartment ”F 12-
13.
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 be
checked 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 reservoir is
empty, remove the radiator cap (non-turbo
models) or the coolant filler tank cap
(turbo models) and refill as required.
NOTE (turbo models only)
The cap (without tabs) on top of the
radiator does not need to be removed.
Remove the cap (with tabs) on the
coolant filler tank on top of the engine.
3. After refilling the reservoir and the
radiator, reinstall the caps after checking
that the rubber gaskets inside the radiator
cap/coolant filler tank cap are in the properposition.

WARNING
Never attempt to remove the radia-
tor cap/coolant filler tank 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
. Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface. Air cleaner element
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
It is not necessary to clean or wash the element.
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the air
cleaner element is not installed
when the engine backfires, you
could be burned.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine. &
Replacing the air cleaner element
Replace the air cleaner element according
to the maintenance schedule in the“ Warranty and Maintenance Booklet ”. Un-
der extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts. ! Non-turbo models
1) Connector
2) Clip
3) Clamp
4) Air intake boot
5) Clip
1. Unplug the connector that is attached
to the top of the air cleaner case.
2. Detach the clip on the connector cable
from the right side of the air cleaner case. Maintenance and service

Washer fluid level gauge
Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the “Low ”mark, add
fluid until it reaches the “Hi ”level on the level gauge or the
“FULL ”mark on the
tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable, use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
Washer Fluid
Concentration Freezing
Temperature
30% 10.48F( 12 8C)
50% 48F( 20 8C)
100% 49 8F( 45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the washer tank with a fluid with a
different concentration from the one used
previously, purge the old fluid from the
piping between the washer tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in the piping is too low for the outside
temperature, it may freeze and block thenozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the washer tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
. Never use engine coolant as
washer fluid because it could
cause paint damage.
