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 radiator cap so that engine coolant will
drain faster.
4) Install the drain plug.
2. FILLING OF ENGINE COOLANT
1) Pour engine coolant into the radiator up to the
filler neck position.
Coolant capacity (fill up to "FULL" level):
MT model
7.3 2 (7.7 US qt, 6.4 Imp qt)
AT model
Model without ATF warmer
7.2 2 (7.6 US qt, 6.3 Imp qt)
Model with ATF warmer (LHD)
7.7 2 (8.1 US qt, 6.8 Imp qt)
Model with ATF warmer (RHD)
7.8 2 (8.2 US qt, 6.9 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.
Engine Coolant
2) Fill engine coolant into the reservoir tank up to
the "FULL" level.
3) 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.)
4) Wait for one minute after the engine stops, open
the radiator cap. If the engine coolant level drops,
CO-02012 add engine coolant into radiator up to the filler neck
position.
5) Perform the procedures 3) and 4) again.
6) Attach the radiator cap and reservoir tank cap
properly.
7) Start the engine and operate the heater at max-
imum hot position and the blower speed setting to
"LO".
8) Run the engine at less than 2,000 rpm until the
radiator fan starts and then 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.
9) Stop the engine and wait until engine coolant
temperature lowers to 30°C (86°F).
10) 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.
11) Attach the radiator cap and reservoir tank cap
properly.
12) 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 the heater core, re-
peat the procedures from 8).
