A: REPLACEMENT
1. DRAINING OF ENGINE COOLANT
1) Lift-up the vehicle.
2) Remove the under cover.
3) Remove the drain plug to drain engine coolant
into container.
NOTE:
Remove the radiator cap so that engine coolant will
drain faster.
4) Install the drain plug.
2. FILLING OF ENGINE COOLANT
1) Pour cooling system conditioner through the fill-
er neck.
Cooling system protective agent:
COOLING SYSTEM CONDITIONER (Part No.
SOA345001)
2) Pour engine coolant into the radiator up to the
filler neck position.
Coolant level:
Refer to “SPECIFICATION” for the engine
coolant capacity. SPECIFICATION, General Description.>
NOTE:
The SUBARU Genuine Coolant containing anti-
freeze and anti-rust agents is especially made for
SUBARU engine, which has an aluminum crank-
case. Always use SUBARU Genuine Coolant,
since other coolant may cause corrosion.
3) Open the air bleeding valve on the heater hose
side.
4) If the engine coolant level drops, add engine
coolant into radiator up to the filler neck position.
5) When engine coolant has come out from the air
bleeding valve on the heater hose side, close the
valve.
6) Open the air bleeding valve on the radiator side.
7) If the engine coolant level drops, add engine
coolant into radiator up to the filler neck position.
8) When engine coolant has come out from the air
bleeding valve on the radiator side, close the valve.
9) Fill engine coolant into the reservoir tank up to
“FULL” level.
10) Close the radiator cap and start the engine.
Race 5 to 6 times at less than 3,000 rpm, then stop
the engine. (Complete this operation within 40 sec-
onds.)

11) Wait for one minute after the engine stops,
open the radiator cap. If the engine coolant level
drops, add engine coolant into radiator up to the fill-
er neck position.
12) Perform the procedures 10) and 11) again.
13) Attach the radiator cap and reservoir tank cap
properly.
14) Start the engine and operate the heater at max-
imum hot position and the blower speed setting to
“LO.”
15) Run the engine at 2,000 rpm or less until radia-
tor fan starts and stops.
NOTE:
•Be careful with the engine coolant temperature
gauge to prevent overheating.
•If the radiator hose becomes harden with the
pressure of engine coolant, air bleeding operation
seems to be almost completed.
16) Stop the engine and wait until the engine cool-
ant temperature lowers to 30°C (86°F).
17) Open the radiator cap. If the engine coolant lev-
el drops, add engine coolant into radiator up to the
filler neck position and reservoir tank to the “FULL”
level.
18) Attach the radiator cap and reservoir tank cap
properly.
19) Set the heater setting to maximum hot position
and the blower speed setting to “LO” and start the
engine. Perform racing at less than 3,000 rpm. If
the flowing sound is heard at this time, perform the
procedures from 15) again.

CONCENTRATION AND FREEZING TEM-
PERATURE
The concentration and safe operating temperature
of SUBARU coolant is shown in the diagram. Mea-
suring the temperature and specific gravity of the
coolant will provide this information.
[Example]
If the coolant temperature is 25°C (77°F) and its
specific gravity is 1.054, the concentration is 35%
(point A), the safe operating temperature is –14°C
(7°F) (point B), and the freezing temperature is –
20°C (–4°F) (point C).

1. REPLACEMENT OF ENGINE COOLANT
WARNING:
The radiator is of the pressurized type. Do not
attempt to open the radiator cap immediately
after the engine has been stopped.
1) Lift-up the vehicle.
2) Remove the under cover.
3) Place a container under drain pipe.
4) Remove the drain cock to drain engine coolant
into container.
5) For quick draining, open the radiator cap.
NOTE:
Be careful not to spill coolant on the floor.
6) Drain the coolant from reservoir tank.
7) Tighten the radiator drain cock securely after
draining coolant.
8) Pour cooling system conditioner through the fill-
er neck.
Cooling system protective agent:
Cooling system conditioner (Part number:
SOA345001)
9) Fill engine coolant into the reservoir tank up to
“FULL” level.
Recommended engine coolant:
Refer to “RM” section. ANT, RECOMMENDED MATERIALS, Recom-
mended Materials.>
Coolant capacity (fill up to “FULL” level):
Approx. 7.4 2 (7.8 US qt, 6.5 Imp qt)
NOTE:
The SUBARU Genuine Coolant containing anti-
freeze and anti-rust agents is especially made for
SUBARU engine, which has an aluminum crank-
case. Always use SUBARU Genuine Coolant,
since other coolant may cause corrosion.
10) Close the radiator cap, and start the engine.
Race 5 to 6 times at 3,000 rpm or less, then stop
the engine. (Complete this operation within 40 sec-
onds.)
11) Wait for one minute after the engine stops, then
open the radiator cap. If the engine coolant level
drops, add engine coolant into radiator up to the fill-
er neck position.
12) Perform the procedures 10) and 11) again.
13) Install the radiator cap and reservoir tank cap
properly.
14) Start the engine and operate the heater at max-
imum hot position and the blower speed setting to
“LO”.
15) Run the engine at 2,000 rpm or less until radia-
tor fan starts and stops.
NOTE:
•Be careful with the engine coolant temperature
gauge to prevent overheating.
•If the radiator hose becomes harden by engine
coolant pressure at this time, air purge seems to be
mostly completed.
16) Stop the engine and wait until the engine cool-
ant temperature lowers to 30°C (86°F).
17) Open the radiator cap. If the engine coolant lev-
el drops, add engine coolant into the coolant filler
tank up to the filler neck position and the reservoir
tank to “FULL” level.
18) Install the radiator cap and reservoir tank cap
properly.
19) Set the heater setting to maximum hot position
and the blower speed setting to “LO” and start the
engine. Perform racing at less than 3,000 rpm. If
the flowing sound is heard from heater core, repeat
the procedures from step 10).
