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
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen-
uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
NOTE (Turbo model only)
The cap (without tabs) on top of the ra-
diator does not need to be removed. To add coolant, remove the cap (with tabs)
on the coolant tank on top of the en-
gine.
4. Install the under cover.
Non-turbo models
1) Filler neck
2) Fill up to this level
Be careful not to spill engine cool-
ant 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.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.

Battery

Before beginning work on or near
any battery, be sure to extinguish
all cigarettes, matches, and light-
ers. Never expose a battery to an
open flame or electric sparks. Bat-
teries give off a gas which is high-
ly flammable and explosive.
For safety, in case an explosion
does occur, wear eye protection
or shield your eyes when working
near any battery. Never lean over
a battery.
Do not let battery fluid contact
eyes, skin, fabrics, or paint be-
cause battery fluid is a corrosive
acid. If battery fluid gets on your
skin or in your eyes, immediately
flush the area with water thor-
oughly. Seek medical help imme-
diately if acid has entered the
eyes.
If battery fluid is accidentally
swallowed, immediately drink a
large amount of milk or water, and
seek medical attention immediate-
ly.
