Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) and the radiator cap tester adapter [SST],
apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows.

Be careful not to bend or damage the radiator fins.

When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator
shroud and horns. Then tape harness and electrical connectors to prevent water from entering.
1. Apply water by hose to the back side of radiator core vertically downward.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.

Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm2 , 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
CHECKING COOLING SYSTEM FOR LEAKS

To check for leaks, apply pressure to the cooling system with
radiator cap tester (commercial service tool) and radiator cap
tester adapter [SST].
WARNING:
Do not remove radiator cap when engine is hot. Serious
burns could occur from high-pressure engine coolant
escaping from radiator.
CAUTION:
Higher testing pressure than specified may cause radiator
damage.
NOTE:
In a case engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.Standard:
78 - 98 kPa (0.78 - 0.98bar, 0.8 - 1.0 kg/cm

PRECAUTIONS

PRECAUTIONSPFP:00001
CautionBES0003W

When installing rubber bushings, final tightening must be performed under unladen conditions with tires
on ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
–Unladen conditions mean that fuel, engine coolant and lubricant are full. A spare tire, a jack, hand tools
and mats are in designated positions.

After servicing suspension parts, be sure to check wheel alignment.

Self-locks nut are not reusable. Always use new ones when installing. Since new self-lock nut are pre-
oiled, tighten as they are.

On-Vehicle Inspection BES00040
Make sure that the mounting conditions (looseness, back lash) of each components and component status
(wear, damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
Measure axial end play by placing an iron pry bar or a similar item between suspension arm and axle housing
prying up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage installation position by applying excessive
force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage, and breakage of installation positions.
Wheel Alignment InspectionBES00041
DESCRIPTION
Measure the wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” mean that fuel, engine coolant, and lubricant are full. A spare tire, a jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
1. Check tires for improper air pressure and wear.
2. Check road wheels for runout. Refer to WT-3, "
ROAD WHEEL" .
3. Check wheel bearing axial end play. Refer to RAX-3, "
WHEEL BEARING INSPECTION" .
4. Check suspension arm ball joint axial end play. Refer to RSU-11, "
Ball Joint Inspection" .
5. Check shock absorber operation.
6. Check each mounting point of axle housing and suspension for looseness and deformation.
7. Check each link, arm, and member for cracks, deformation, and other damage.
8. Check vehicle height (posture).
CAMBER INSPECTION

Measure camber of both right and left wheels with a suitable
alignment gauge.

Adjust in accordance with the following procedures.

If camber is not within the specification, adjust by turning the
adjusting bolt of front lower link.
NOTE:
After adjusting camber, be sure to check toe-in.Axial end play : 0 mm (0 in)
