2012 SUBARU FORESTER check engine

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

the engine has stopped.
& When checking or servicing
in the engine compartment
while the engine is running
WARNING
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, belts and any other moving
engine parts. Removing rings,
watches and ties is advisable. Engine hood
To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their originalposition.
2. Pull the hood release knob under the
instrument panel.
3. Release the secondary hood latch by
moving the lever between the front grille
and the hood toward the left.
4. Lift up the hood.
To close the hood:
1. Lower the hood to a height of approxi-
mately 5.9 in (15 cm) above its closed
position and then let it drop.
2. After closing the hood, be sure the
hood is securely locked.
If this does not close the hood, release it
from a slightly higher position. Do not push
thehoodforciblytocloseit.Itcould
deform the metal.Maintenance and service

Engine oil NOTE .The engine oil consumption rate is
not stabilized, and therefore cannot be
determined until the vehicle has tra-
veled at least several thousand miles
(kilometers). Even after break-in, when
the vehicle is used under severe driv-
ing conditions such as those men-
tionedintheWarrantyandMainte-
nance Booklet, engine oil is consumed
or deteriorated more quickly than un-
der normal driving conditions. If you
drive your vehicle under these severe
conditions, you should check the oil
level at least at every second fuel fill-up
time, and change the oil more fre-
quently. Please refer to the Warranty
and Maintenance Booklet for more de-tails.. If the oil consumption rate seems
abnormally high after the break-in
period, for example more than 1 quart
per 1,200 miles (1 liter per 2,000 kilo-
meters), contact your SUBARU dealer. &
Checking the oil level
Check the engine oil level at each fuelstop.
1. Park the vehicle on a level surface and
stop the engine. Wait a few minutes for the
oil to drain back into the oil pan.

3. Be sure the level gauge is correctly
inserted until it stops. For turbo models,
the graphic symbol “
”on the top of the
gauge should be positioned as shown in
the illustration.
4. Pull out the oil level gauge again.5. Non-turbo models:
Check the oil levels on both sides of the
level gauge. The engine oil level must be
judged by the lowest of the two levels. If
the oil level is below the low level mark,
add oil so that the full level is reached. Turbo models:
Check the oil level on the gauge. If the oil
level is below the low level mark, add oil
so that the full level is reached.
CAUTION
. For non-turbo models, be careful
not to touch the engine oil filter
when removing the oil filler cap.
Doing so may result in a burn, a
pinched finger, or may cause
some other injury.
. Use only engine oil with the
recommended grade and vis-
cosity.
. Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.
To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level iscorrect.

NOTE .Just after driving or while the engine
is warm, the engine oil level reading
may be in a range between the full level
and the notch mark (turbo models).
This is caused by thermal expansion of
the engine oil.. To prevent overfilling the engine oil,
do not add any additional oil above the
full level when the engine is cold. & Changing the oil and oil filter
CAUTION
. If you change your own oil, be
sure to drain all the oil from the
filter before disposal.
. Do not dispose of used engine oil
by placing it in the trash, or by
pouring it onto the ground, into
sewers, or into any body of water.
Check with your local govern-
ment office for the proper dis-
posal options available to you.
Change the oil and oil filter according to
the maintenance schedule in the “War-
ranty and Maintenance Booklet ”.
The engine oil and oil filter must be
changed more frequently than listed in
the maintenance schedule when driving on dusty roads, when short trips are
frequently made, or when driving in
extremely cold weather.
1. Warm up the engine by letting the
engine idle for approximately 10 minutes
to ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.
Turbo models
Non-turbo models
4. Drain out the engine oil by removing
the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
WARNING
Be careful not to burn yourself with
hot engine oil.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it
securely with a new sealing washer after
the oil has completely drained out.
6. Remove the under cover (turbo mod- els). Maintenance and service

7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a
thin coat of engine oil to the seal. 9. Clean the seal seating area. Screw on
the oil filter by hand until its seal contacts
the seating surface. Be careful not to twist
or damage the seal.
10. Tighten the oil filter further by the
amount indicated in the following table.

Blue 15208AA12A 7/8
rotation
Non-turbo models Oil filter color Part number Amount of
rotation
Black 15208AA130 3/4 rotation
15208AA160
1 rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire. 11. Reinstall under cover (turbo models).
12. Pour engine oil through the filler neck.
For the oil capacity guideline, refer to “
Engine oil ”F 12-5.
The oil quantity indicated above is onlyguideline.
The necessary quantity of oil depends on
the quantity of oil that has been drained.
The quantity of drained oil differs slightly
depending on the temperature of the oil
and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must use the level gauge to confirm that
the level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter ’s rubber
seal and drain plug.
14. Run the engine until it reaches the
normal operating temperature. Then stop
the engine and wait a few minutes to allow
the oil drain back. Check the oil level
again and if necessary, add more engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire.
