1. DRAINING OF ENGINE COOLANT
1) Set the vehicle on a lift.
2) Lift up the vehicle.
3) Remove the under cover RH.
4) Remove the drain plug (A) to drain engine cool-
ant into container.
NOTE:
Remove the radiator cap so that engine coolant will
drain faster.
5) Install the drain plug.
6) Install the under cover RH.
2. FILLING OF ENGINE COOLANT
1) Pour cooling system conditioner through the fill-
er neck.
Cooling system protective agent:
Refer to “SPECIFICATION” for cooling sys-
tem protective agent. <Ref. to CO(H4SO)-2,
SPECIFICATION, General Description.>
2) Pour engine coolant into the radiator up to the
filler neck position.
Recommended engine coolant:
Refer to “SPECIFICATION” for recommended
engine coolant. <Ref. to CO(H4SO)-2, SPECI-
FICATION, General Description.>
Engine coolant level:
Refer to “SPECIFICATION” for engine cool-
ant level. <Ref. to CO(H4SO)-2, SPECIFICA-
TION, General Description.>
Engine coolant concentration:
Refer to “ADJUSTMENT” for the recommended
engine coolant concentration. <Ref. to
CO(H4SO)-14, ADJUSTMENT, Engine Coolant.>
NOTE:
The SUBARU Super Coolant contains anti-freeze
and anti-rust agents, and is especially made for
Subaru engines with an aluminum cylinder block.
Always use SUBARU Super 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 3,000 rpm or less, then stop
the engine. (Complete this operation within 40 sec-
onds.)
5) Wait for one minute after the engine stops, and
open the radiator cap. If the engine coolant level
drops, add engine coolant into radiator up to the fill-
er 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 to
“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.
10) Stop the engine and wait until the engine cool-
ant temperature drops to 30°C (86°F) or less.
11) Open the radiator cap. If the engine coolant lev-
el drops, add engine coolant into the radiator up to
the filler neck position and the reservoir tank to
“FULL” level.
12) Attach the radiator cap correctly.
13) Set the heater setting to maximum hot position
and the blower speed setting to “LO” and start the
engine. Perform racing at 3,000 rpm or less. If the
flowing sound is heard from heater core at this
time, perform the procedures from 9) again.
