A: REPLACEMENT
1. REPLACEMENT OF 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) Loosen and remove the drain cock to drain en-
gine coolant into container.
5) For quick draining, open the radiator cap.
CAUTION:
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) Slowly pour the coolant from radiator filler port to
neck of filler, then pour into reservoir tank up to
"FULL" level.
Coolant capacity (fill up to "FULL" level)
Turbo AT model:
Approx. 7.3 2 (7.7 US qt, 6.4 Imp qt)
Turbo MT model:
Approx. 7.4 2 (7.8 US qt, 6.5 Imp qt)
Non-turbo AT model:
Approx. 6.8 2 (7.2 US qt, 6.0 Imp qt)
Non-turbo MT model:
Approx. 6.9 2 (7.3 US qt, 6.1 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.
9) Securely install the radiator cap.
10) Run the engine for more than 5 minutes at
2,000 to 3,000 rpm. (Run the engine until radiator
becomes hot in order to purge the air trapped in
cooling system.)
COOLANT
11) Stop the engine and wait until coolant temper-
ature lowers. Then open the radiator cap to check
coolant level and add coolant up to radiator filler
neck. Next, add coolant into reservoir tank up to
"FULL" level.
12) After adding coolant, securely install the radia-
tor and reservoir tank caps.
2. RELATIONSHIP OF SUBARU COOLANT
CONCENTRATION AND FREEZING TEM-
PERATURE
The concentration and safe operating temperature
of the SUBARU Genuine Coolant is shown in the
diagram. Measuring 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).
