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 number
SOA635071)
2) Pour engine coolant into the radiator up to the
filler neck position.
Coolant capacity (fill up to “FULL” level):
MT model:
6.4
2
(6.8 US qt, 5.6 Imp qt)
AT model:
6.3
2
(6.7 US qt, 5.5 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.
3) Fill engine coolant into the reservoir tank up to
“FULL” level.
4) 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.)
5) 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 filler neck
position.
6) Perform the procedures 4) and 5) again.
7) Attach the radiator cap and reservoir tank cap
properly.
8) Start the engine and operate the heater at max-
imum hot position and the blower speed setting at
“LO”
9) Run the engine at 2,000 rpm or less until radiator
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.
10) Stop the engine and wait until the engine cool-
ant temperature lowers to 30°C (86°F).
11) 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.
12) Attach the radiator cap and reservoir tank cap
properly.
13) 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 9) again.
