General Description
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
5. O-RING CONNECTIONS
•Always use a new O-ring.
•In order to keep the O-rings free of lint which can
cause a refrigerant gas leak, perform operations
without gloves and cloth.
•Apply compressor oil to O-rings to avoid sticking,
before installation.
•Use a torque wrench to tighten the O-ring fittings.
Over-tightening will cause damage to the O-ring
and cause tube end distortion.
•If the work is interrupted before completing pipe
connections, recap the tubes, components and fit-
tings with a plug or tape to prevent foreign matter
from entering.
•Visually check the surfaces and mating surfaces
of O-rings, threads and connecting points. If a fail-
ure is found, replace the applicable parts.
•Install the O-rings at a right angle to tube beads.
•Use compressor oil specified in the service man-
ual to lubricate the O-rings.
Apply oil to the top and sides of O-rings before in-
stallation.
Apply compressor oil to grooves of the tube.
•After tightening, use a clean cloth to remove ex-
cess compressor oil from the connections and any
oil which may have run on the vehicle body or other
parts.
•If any leakage is suspected after tightening, do
not tighten the connections further, but disconnect
the connections, remove the O-rings, and check
the O-rings, threads, and connections.
D: PREPARATION TOOL
CAUTION:
When working on vehicles with a HFC-134a
system, only use HFC-134a specified tools and
parts. Do not mix CFC-12 tools and parts. If
HFC-134a and CFC-12 refrigerant or compres-
sor oil is mixed, it will result in poor lubrication
and the compressor itself may be damaged.
In order to prevent the mixture of HFC-134a and
CFC-12 parts and liquid, the tool and screw
type and the type of service valves used are dif-
ferent. The gas leak detectors for the HFC-134a
and CFC-12 systems must also not be inter-
changed.

Power Steering Fluid
POWER ASSISTED SYSTEM (POWER STEERING)
9. Power Steering Fluid
A: SPECIFICATION
B: INSPECTION
1) Check the power steering fluid for deterioration
or contamination. If the fluid is highly deteriorated
or contaminated, drain it and refill with new fluid.
2) Check the joints and units for oil leakage. If any
oil leaks are found, repair or replace the applicable
part.
3) Inspect the fluid level of reservoir tank with vehi-
cle on level surface and engine stopped.
If the level is at “MIN. ” point or below, add fluid to
keep the level in the specified range of the indica-
tor. If at “MAX. ” point or above, drain fluid by using
a syringe or the like.
(1) Check at power steering fluid temperature
20°C (68°F); read the fluid level on the “COLD”
side.
(2) Check at power steering fluid temperature
80°C (176°F); read the fluid level on the “HOT”
side.
C: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the crossmember support.
3) Remove the pipe joint in the center of gearbox,
and connect the vinyl hose to the pipe and joint.
Wipe fluid off while turning the steering wheel.
4) Add the specified fluid to reservoir tank at “MAX”
level.
5) Continue to turn the steering wheel slowly from
lock to lock until the bubbles stop appearing on oil
surface while keeping the fluid at the level in the
Step 4).
6) If the steering wheel is turned in a low fluid level
condition, air will be sucked into the pipe. If sucked,
leave it about half an hour and then do the step 5)
again.
7) Start the engine and let it idle.
8) Continue to turn the steering wheel slowly from
lock to lock again until the bubbles stop appearing
on oil surface while keeping the fluid at the level in
Step 4).
Normally bubbles will stop appearing after turning
the steering wheel from lock to lock three times.
9) In case bubbles do not stop appearing in the
tank, leave it about half an hour and then do the
step 4) all over again.
10) Lower the vehicle, and then idle the engine.
11) Continue to turn the steering wheel from lock to
lock until the bubbles stop appearing and change of
the fluid level is within 3 mm (0.12 in).
12) In case the following happens, leave it about
half an hour and then do step 8) to 11) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the
fluid.
(3) Grinding noise is generated from oil pump.
13) Check the fluid leakage after turning steering
wheel from lock to lock with engine running.

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.
