2002 SUBARU OUTBACK engine coolant

11-14
Cooling systemWARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33°F ( –36 °C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehicle employs an electric cooling fan which is thermostatically
controlled to operate when the engine coolant reaches a specific tem-
perature.If the radiator cooling fan does not operate even when the engine
coolant temperature gauge exceeds the normal operating range, the
cooling fan circuit may be defective. Check the fuse and replace it if
necessary. 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 systemand connections be checked for leaks, damage, or looseness.

Engine coolant Checking the coolant level
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, re-
move the radiator cap and refill as required.

Rubber gaskets
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.

Changing the coolant
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
Change the engine coolant using the following procedures according
to the maintenance schedule in the “Warranty and Maintenance Book-
let”. 1. Remove the under cover.
2. Place a proper container under the drain plug and loosen the drainplug.

3. Loosen the radiator cap to drain the coolant from the radiator. Then
drain the coolant from the reserve tank. Tighten the drain plug secure-
ly.

4. Slowly pour the coolant and fill to the radiator filler neck and to the
reserve tank ’s “FULL” level mark. Do not pour the coolant too quickly,
as this may lead to insufficient air bleeding and trapped air in the sys-tem.

Rubber gaskets
5. Put the radiator cap back on and tighten firmly. At this time, make
sure that the rubber gasket in the radiator cap is correctly in place.
6. Start and run the engine for more than five minutes at 2,000 to
3,000 rpm.

7. Stop the engine and wait until the coolant cools down (122 to 140°F [50 to 60 °C]). If there is any loss of coolant, add coolant to the
radiator’ s filler neck and to the reserve tank ’s “FULL” level.
8. Put the radiator cap and reservoir cap back on and tighten firmly.
Air cleaner 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.
The air cleaner element functions as a filter screen. When the element is
perforated or removed, engine wear will be excessive and engine life
shortened.
The air cleaner element is a viscous type. It is unnecessary to clean or wash the element. Replacing the air cleaner element
Replace the air cleaner element according to the maintenance sched-ule in the “Warranty and Maintenance Booklet ”. Under extremely
dusty conditions, replace it more frequently. It is recommended that
you always use genuine SUBARU parts.

tighten it to the specified torque.
Aluminum wheels (If equipped)
Aluminum wheels can be scratched and damaged easily. Handle them
carefully to maintain their appearance, performance, and safety. When any of the wheels is removed and replaced for tire rotation or to
change a flat, always check the tightness of the wheel nuts after driving
approximatly 600 miles (1,000 km). If any nut is loose, tighten it to the
specified torque. Never apply oil to the threaded parts, wheel nuts, or tapered surface
of the wheel. Never let the wheel rub against sharp protrusions or curbs.
Be sure to fit tire chains on uniformly and completely around the tire,
otherwise the chains may scratch the wheel. When wheel nuts, balance weights, or the center cap is replaced, be
sure to replace them with genuine SUBARU parts designed for aluminumwheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer fluid because it could cause paint damage.
Check the level of the washer fluid at each fuel stop. If the level is low, fill
the fluid up to the neck of the reservoir.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 temperature varies
according to how much it is diluted, as indicated below.
