2. RELATIONSHIP OF SUBARU COOLANT
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).
3. PROCEDURE TO ADJUST THE CON-
CENTRATION OF THE COOLANT
To adjust the concentration of coolant according to
temperature, find the proper fluid concentration in
the above diagram and replace the necessary
amount of coolant with an undiluted solution of
SUBARU genuine coolant (concentration 50%).
The amount of engine coolant that should be re-
placed can be determined using the diagram.
[Example]
Assume that the engine coolant concentration must
be increased from 25% to 40%. Find point A, where
the 25% line of engine coolant concentration inter-
sects with the 40% curve of the necessary engine
coolant concentration, and read the scale on the
vertical axis of the graph at height A. The quantity
of coolant to be drained is 2.12;(2.2 US qt, 1.8 Imp
qt). Drain 2.1 2(2.2 US qt, 1.8 Imp qt) of coolant
from the cooling system and add 2.1 2(2.2 US qt,
1.8 Imp qt) of the undiluted solution of SUBARU
coolant.
If a coolant concentration of 50% is needed, drain
all the coolant and refill with the undiluted solution
only.

3) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 500 N (51 kgf, 112 lb) load and measure the
distance between the brake pedal and steering
wheel. With the brake pedal released, measure the
distance between pedal and steering wheel again.
The difference between the two measured values
must be less than specified value. If the measured
value is more than specification, there is possibility
of entering air in hydraulic unit.
Brake pedal stroke A:
115 mm (4.5 in)/ 500 N (51 kgf, 112 kg) or less
4) 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.
3. 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) A check valve is incorporated into the vacuum
hose part. Disconnect the vacuum hose to inspect
function of check valve.
Make sure air flows from the booster end to engine
end but does not flow in the opposite direction in
the check valve.
5) Check the vacuum hose for cracks or other dam-
age.
NOTE:
When installing the vacuum hose on the engine
and brake booster, do not use soapy water or lubri-
cating oil on their connections.
6) Check the vacuum hose to make sure it is tightly
secured.

A: INSPECTION
1. SUSPENSION BALL JOINT
1) Jack-up the vehicle until front wheels are off
ground.
2) Grasp the bottom of tire and move it in and out
along the shaft. If relative movement is observed
between the brake disc cover (A) and end of front
arm (D), ball joint (C) may be excessively worn.
3) Grasp the end of front arm and move it up and
down. Relative movement (A) between the housing
(D) and front arm (C) boss indicates ball joint (B)
may be excessively worn.
4) If relative movement is observed in the step 2),
3), remove and inspect the ball joint. If the free play
exceeds standard value, replace the ball joint.

5) Damage of dust seal
Visually inspect the ball joint dust seal. If it is dam-
aged, remove the front arm. Arm.> Also, measure the free play of the ball joint.

(1) When looseness exceeds standard value,
replace the ball joint.
(2) If the dust seal is damaged, replace with a
new ball joint.
NOTE:
When the front arm ball joint has been removed or
replaced, check the toe-in of front wheel. If the front
wheel toe-in is not at specified value, adjust the
toe-in.
2. FRONT, REAR SUSPENSION BUSHING
Apply pressure with tire lever etc, and inspect the
bushing for wear or crack. Replace the bushings
and the arm assembly or link assembly if there is
wear or there are cracks.
3. WHEEL ARCH HEIGHT
1) Unload the cargo and set the vehicle in curb
weight (empty) condition.
2) Check the wheel arch height of the front and rear
suspensions to ensure that they are within speci-
fied values.
3) When the wheel arch height is out of standard,
visually inspect following components and replace
deformed parts.
•Suspension components [Front strut assembly
and rear shock absorber assembly]
•Parts connecting suspension and body
4) When no components are deformed, adjust
wheel arch height by replacing coil spring in the
suspension whose wheel arch height is out of stan-
dard. RS-7, Wheel Alignment.>

2) Measure the depth “A” from the mating surface
of the extension case to the multi-plate clutch

3) Using the ST, measure the height “B” from the
AT main case mating surface to end of ST, and
then subtract the thickness of ST (piston guide) (50
mm (1.97 in)) from measured value.
