3. Engine Coolant
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 coolant filler tank cap so that engine
coolant will drain faster.
4) Install the drain plug.
2. FILLING OF ENGINE COOLANT
1) Remove the collector cover.
2) Fill engine coolant into coolant filler tank up to
the filler neck position.
Coolant capacity (fill up to "FULL" level):
AT model (model with ATF warmer)
7.72(8.1 US qt, 7.1 Imp qt)
AT model (model without ATF warmer)
7.32(7.7 US qt, 6.4 Imp qt)
MT model
7.42(7.8 US qt, 6.5 Imp qt)
CAUTION:
Do not confuse the cap of coolant filler tank
with that of radiator.
NOTE:
• When pouring the engine coolant, the radiator
side cap must not be removed.
• 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 coolant filler tank cap, start the engine
and race 5 to 6 times at less than 3,000 rpm, then
stop the engine. (Complete this operation within 40
seconds.)

5) Wait for one minute after the engine stops, open
the coolant filler tank cap. If the engine coolant lev-
el drops, add engine coolant to the filler neck posi-
tion of radiator.
6) Perform the procedures 4) and 5) again.
7) Attach the coolant filler tank 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 ratiator
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.
10) Stop the engine and wait until engine coolant
temperature lowers to 30°C (86°F) or less.
11) Open the coolant filler tank cap. If the engine
coolant level drops, add engine coolant into the
CO-00248
coolant filler tank up to the filler neck position and
the reservoir tank to "FULL" level.
12) Attach the coolant filler tank cap and reservoir
tank cap properly.
13) Operate the heater at maximum hot position
and the blower speed setting to "LO" and start the
engine. Race at less than 3,000 rpm. If the flowing
sound is heard from heater core, repeat the proce-
dures from step 9).
14) Install the collector cover.
