CAUTION:
When measuring the voltage and resistance of each control module or sensor, use a tapered pin with
a diameter of less than 0.64 mm (0.025 in) in order to avoid poor contact. Do not insert the pin more
than 2 mm (0.08 in).

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 cooling system conditioner through the fill-
er neck.
Cooling system protective agent:
COOLING SYSTEM CONDITIONER (Part No.
SOA345001)
2) Pour engine coolant into the radiator up to the
filler neck position.
Coolant level:
Refer to “SPECIFICATION” for the engine
coolant capacity. SPECIFICATION, General Description.>
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) Open the air bleeding valve on the heater hose
side.
4) If the engine coolant level drops, add engine
coolant into radiator up to the filler neck position.
5) When engine coolant has come out from the air
bleeding valve on the heater hose side, close the
valve.
6) Open the air bleeding valve on the radiator side.
7) If the engine coolant level drops, add engine
coolant into radiator up to the filler neck position.
8) When engine coolant has come out from the air
bleeding valve on the radiator side, close the valve.
9) Fill engine coolant into the reservoir tank up to
“FULL” level.
10) 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.)

11) 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 fill-
er neck position.
12) Perform the procedures 10) and 11) again.
13) Attach 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 with the
pressure of engine coolant, air bleeding operation
seems to be almost 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 radiator up to the
filler neck position and reservoir tank to the “FULL”
level.
18) Attach 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 at this time, perform the
procedures from 15) again.

CONCENTRATION AND FREEZING TEM-
PERATURE
The concentration and safe operating temperature
of SUBARU coolant is shown in the diagram. Mea-
suring the temperature and specific gravity of the
coolant will provide this information.
[Example]
If the coolant temperature is 25°C (77°F) and its
specific gravity is 1.054, the concentration is 35%
(point A), the safe operating temperature is –14°C
(7°F) (point B), and the freezing temperature is –
20°C (–4°F) (point C).

•Leakage from the radiator or its vicinity
•Leakage from the hose or its connections
CAUTION:
•Engine should be turned off.
•Wipe engine coolant from check points in ad-
vance.
•Be careful of the spurt of engine coolant
when removing the tester.

1. OUTLINE OF DIAGNOSIS
Detect the malfunction of engine coolant temperature sensor characteristics.
The engine coolant temperature and fuel temperature is stored in memory from the last time that the engine
was stopped. If the engine coolant temperature does not decrease when it is expected to after starting the
engine, it is judged to be NG.
