2.For non-turbo, remove the ‘drain plug from
block to drain engine coolant.
For turbo, remove the water hose from the water pip e
assembly (C) to do so.
3.

5.Remove the reserve tank to drain the coolant.
When the engine coolant has drained, pour in water from
the cap to clean the engine coolant line.
For non-turbo, install the drain plug to the cylind er block.
For turbo, install the water hose to pipe assembly

8.
Securely tighten the radiator drain plug.
Install the reserve tank.
9.
Slowly pour the engine coolant into the mouth of th e
radiator until the radiator is full, and pour also into the
reserve tank up to the FULL line.
Recommended antifreeze:
LONG-LIFE COOLANT (Part No. 0103044)
or high quality ethylene-glycol antifreeze coolant)
Quantity 7.0
(7.4 qts.)
Install the cap securely.
Start the engine and warm the engine until the the rmostat
opens. (Touch the radiator hose with your hand to c heck
that warm water is flowing.)
11. After the thermostat opens, race the engine at 3,000
3 times.
12. After the engine is stopped, wait until the eng ine has
cooled down, and then remove the cap to check the
level of the liquid. If the level is low, repeat th e operation
from step 9.
Lastly, if the level does not drop, fill the conden se tank
with coolant up to the FULL line.
15. DISC BRAKE PADS (Check for wear)
Check for fluid contamination and wear. Replace com plete
set of pads if defective.
Caution
The pads for the right and left wheels should be re placed
at, the same time. Never “split” or intermix brake pad
sets.
All four pads must be replaced as a complete set.
Thickness of lining (A) Limit: 2.0 mm

l e a k s )
1.Remove the brake drum and check of brake
shoe lining for wear. Check the automatic brake adj usting
system by hand to see if it operates smoothly.
Also see if the gears are in proper mesh with each other.
To assure smooth operation, apply a thin coat of
multipurpose grease to the friction surface of adju ster
and link shaft.

2.Check the wheel cylinder boots for evidence, a’ brake
fluid leak. Visually check the
boots for tears or
cracks. (A slight amount of fluid on the boot may not
be a leak, but may be preservative assembly.)
Caution
The shoes for the right and left be,
replaced at the same time.
Never split or intermix brake
sets.
All four shoes must be replaced as a set.
Thickness of lining
Limit: 1.0 mm in.)
17. BRAKE HOSES (Check for
leaks)
Check of brake hoses and tubing should be
brake service operations.
The hoses should be checked for:
1.Correct length, severe surface cracking, pulling, scuffing
or worn spots. (If the fabric casing of the hoses i s exposed
by cracks of abrasion in the rubber hose cover, the hoses
should be replaced. Eventual deterioration of may
occur with possible bursting failure.)
2. Faulty installation, casing twisting or interfer ence
wheel,’ tire or chassis.
18. BALL JOINT AND STEERING SEALS
(Check for grease leaks damage)
1. These components, which are permanently lubricat ed
at the factory, do not require periodic lubrication. Damaged
seals and boots should be replaced to prevent leakage
or contamination of the grease.
2.Check the dust cover and boots for proper sealing, leakage
and damage. Replace them if defective.
19. DRIVE SHAFT BOOTS (Check for leaks
and damage)
1. These components, which are permanently lubricat ed
at the factory, do not require periodic Damaged
boots should be replaced to prevent leakage or contamina-
tion of the grease.
2.Check the boots for proper sealing, leakage and damage.
Replace it if defective.
AXLE OIL (Check oil level)-AWD
Remove the filler plug and check the oil level at bottom of
filler hole. If the oil level is slightly below the filler hole, it
is in satisfactory condition.

Turn the ignition key to the “ON” position. the
warning light illuminate for about 7 seconds, turn “OFF” and
then remain extinguished for at least 45 seconds? I f yes,

1.Turn the ignition key to position, disconnect the
negative battery cable and tape the ‘terminal.
Caution
Wait at least 60 seconds
disconnecting the bat-
tery cable before doing any further
The SRS system is designed to enough voltage
to deploy the air bag for a short after the
battery has been disconnected, so serlous
result from unintended air bag deployment
is done on the SRS system immediately the
tery cable is disconnected. ,

6. Check clock spring connectors and protective tube for
damage, and terminals for deformities.
7. Visually check the clock spring case for damage.
8.Align the mating mark of the clock spring and, afte r turning
the vehicle’s front wheels to
position, install
the clock spring to the column switch.
Mating mark alignment
Turn the clock spring fully clockwise, and turn bac k it
approx. 3 and
turns counterclockwise to align the
mating marks.
Caution
If the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal op-
eration of the SRS and possibly leading to serious
injury to the vehicle’s driver and passenger.
9. Install the steering column covers, steering whe el and
the air bag module.
10. Check steering wheel for noise, binds of diffic ult operation.
11. Check steering wheel for excessive free play.
