10.Engine Coolant
A: REPLACEMENT
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).

A: REMOVAL
1) Set the vehicle on a lift.
2) Lift-up the vehicle.
3) Remove the under cover.
4) Disconnect the ATF cooler hose from the radia-
tor.
NOTE:
•Do not use a screwdriver or other pointed tools.
•If it is hard to remove the hose, wrap the hose
with cloth to prevent from damaging it, and while
turning with pliers, pull straight out by hand.
5) Disconnect the ATF cooler hoses from the pipes.
NOTE:
•Do not use a screwdriver or other pointed tools.
•If it is hard to remove the hose, wrap the hose
with cloth to prevent from damaging it, and while
turning with pliers, pull straight out by hand.
6) Remove the front bumper.

transmission side.
NOTE:
•Install so that the hose is not folded over, exces-
sively bent or twisted.
•Insert the hose to the specified position.
7) Connect the ATF cooler hose to the pipe on the
radiator side.

•Install so that the hose is not folded over, exces-
sively bent or twisted.
•Insert the hose to the specified position.
8) Install the under cover.

NOTE:
Make sure there are no ATF leaks in joints between
the transmission, radiator, pipes, and hoses.
C: INSPECTION
Repair or replace any faulty hoses, pipes, clips,
and washers found in the inspection below.
1) Check for ATF leaks in joints between the trans-
mission, radiator, pipes, and hoses.
2) Check clips for deformation.
3) Lightly bend the hose and check for cracks in the
surface or other damages.
4) Pinch the hose with your fingers and check for
poor elasticity. Also check for poor elasticity in the
parts where the clip was installed by pressing with
your fingernail.
5) Check for peeling, cracks, and deformation at
the tip of the hose.

Working Precautions
WIRING SYSTEM
2. Working Precautions
A: PRECAUTIONS WHEN WORKING
WITH THE PARTS MOUNTED ON
THE VEHICLE
1) When working under a vehicle which is jacked-
up, always be sure to use rigid rack.
2) The parking brake must always be applied dur-
ing working. Also, in automatic transmission vehi-
cles, keep the select lever set to the P (Parking)
range.
3) Be sure the workshop is properly ventilated
when running the engine. Further, be careful not to
touch the belt or fan while the engine is operating.
4) Be careful not to touch hot metal parts, especial-
ly the radiator and exhaust system immediately af-
ter the engine has been turned off.
B: PRECAUTIONS IN TROUBLE DI-
AGNOSIS AND REPAIR OF ELEC-
TRIC PARTS
1) The battery cable must be disconnected from
the battery’s (–) terminal, and the ignition switch
must be set to the OFF position, unless otherwise
required by the diagnostics.
2) Securely fasten the wiring harness with clamps
and slips so that the harness does not interfere with
the body end parts or edges and bolts or screws.
3) When installing parts, be careful not to catch
them on the wiring harness.
4) When disconnecting a connector, do not pull the
wires, but pull while holding the connector body.
5) Some connectors are provided with a lock. One
type of such a connector is disconnected by push-
ing the lock, and the other, by moving the lock up.
In either type the lock shape must be identified be-
fore attempting to disconnect the connector.
To connect, insert the connector until it snaps and
confirm that it is connected securely.
6) When checking continuity between connector
terminals, or measuring voltage across the terminal
and ground, always contact tester probe(s) on ter-
minals from the wiring connection side. If the probe
is too thick to gain access to the terminal, use “mini”
test leads.
To check water-proof connectors (which are not
measurable from the wiring side), contact test
probes on the terminal side. Be careful not to bend
or damage the terminals.
7) Sensors, relays, electrical unit, etc., are sensi-
tive to strong impacts.
Handle them with care so that they are not dropped
or mishandled.
