CAUTION:
 For turbo model, be sure to install tester to
filler tank side.
 When attaching or detaching tester and when
operating tester, use special care not to deform
radiator filler neck.
 When performing this check, be sure to keep
the engine stationary and fill the radiator with
coolant.
 Wipe off check points before applying pres-
sure.
 Use care not to spill coolant when detaching
the tester from radiator.

2) Check the radiator cap valve open pressure us-
ing radiator cap tester.
Raise the pressure until the needle of gauge stops
and see if the pressure can be retained for 5 to 6
seconds. The radiator cap is normal if a pressure
above the service limit value has been maintained
for this period.CAUTION:
Rust or dirt on the cap may prevent the valve
from functioning normally: be sure to clean the
cap before testing.
Radiator cap valve open pressure

Brake Line
(4) If there is no free play between clevis pin
and clevis, turn the brake switch adjusting nut
until the clearance between stopper and screw
of brake switch becomes 0.3 mm (0.012 in).
3) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 490 N (50 kgf, 110 lb) load and measure the
distance between brake pedal and steering wheel.
With the brake pedal released, measure the dis-
tance between pedal and steering wheel again.
The difference between the two measurements
must be less than specified value. If the distance is
more than specified value, there is possibility of air
inside the hydraulic unit.
Brake pedal reserve distance: A
For Australia model
105 mm (4.13 in)/ 490 N (50 kgf , 110 lb) or less
Except for Australia model
90 mm (3.54 in)/ 490 N (50 kgf , 110 lb) or less4) Check to see if air is in the hydraulic brake line
by the feel of pedal operation. If air appears to exist
in the line, bleed it from the system.
5) Check for even operation of all brakes, using a
brake tester or by driving the vehicle for a short dis-
tance on a straight road.
2. BRAKE SERVO SYSTEM
1) With the engine off, depress the brake pedal
several times applying the same pedal force: Make
sure the travel distance should not change.
2) With the brake pedal depressed, start the en-
gine: Make sure the pedal should move slightly to-
ward the floor.
3) With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds:
Make sure the pedal height should not change.
4) Check valve is built into the vacuum hose. Dis-
connect the vacuum hose to inspect function of
check valve.
Blow air into the vacuum hose from its brake boost-
er side end: Air must flow out of engine side end of
hose. Next blow air into the hose from engine side:
Air should not to brake booster side.
Replace both check valve and vacuum hose if the
check valve is faulty. Engine side of vacuum hose
is indicated by marking “ENG” as shown in illustra-
tion.
5) Check the vacuum hose for cracks or other dam-
age.
CAUTION:
When installing the vacuum hose on the engine
and brake booster, do not use soapy water or
lubricating oil on their connections.
6) Check vacuum hose to make sure it is tight and
secure.

placed level when checking oil level. Use the en-
gine oil of proper quality and viscosity, selected in
accordance with the table in figure.
Recommended oil
API classification SL, SJ with the “Energy
Conserving” logo is printed, or SH (if you
cannot obtain the oil with SL, SJ or SH
grades, you may use SG, SF grades “ENER-
GY CONSERVING” oil.)
ACEA specification, A1, A2 or A3

 Non-turbo model Turbo model
The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
CAUTION:
When replenishing oil, it does not matter if the
oil to be added is a different brand from that in
the engine; however, use oil having the API
classification and SAE viscosity No. designat-
ed by SUBARU.
NOTE:
If the vehicle is used in areas with very high tempera-
tures or for other heavy duty applications, the follow-
ing viscosity oils may be used: API classification: SL
or SJ or SH
SAE Viscosity No. : 30, 40, 10W-50, 20W-40, 20W-
50.
