lCheck suspension ball joint end play.
a. Jack up front of vehicle and set the stands.
b. Clamp dial indicator onto transverse link and place indicator
tip on lower edge of brake caliper.
c. Make sure front wheels are straight and brake pedal is
depressed.
d. Place a pry bar between transverse link and inner rim of road
wheel.
e. While raising and releasing pry bar, observe maximum dial
indicator value.
Vertical end play:
0mm(0in)
f. If ball joint vertical end play exists, remove transverse link
and recheck the ball joint. Refer to ªFRONT SUSPENSIONº,
FA-32.
Front Wheel Bearing
lCheck that wheel bearings operate smoothly.
lCheck axial end play.
Axial end play:
0.05 mm (0.0020 in) or less
lIf axial end play is not within specification or wheel bearing
does not turn smoothly, replace wheel bearing assembly.
Refer to ªWheel Hub and Knuckleº, ªFRONT AXLEº, FA-FA-
11 .
Front Wheel Alignment
Before checking front wheel alignment, be sure to make a pre-
liminary inspection (Unladen*).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand
tools and mats in designated positions.
PRELIMINARY INSPECTION
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove tire and check wheel runout.
Wheel runout:
Refer to SDS, FA-35.
3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.
5. Check steering linkage for looseness.
6. Check that front shock absorbers work correctly by using the
standard bounce test.
7. Check vehicle posture (Unladen).

lBefore starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
lTo prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
lBefore servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate
covers.
Take care that keys, buckles or buttons do not scratch paint.
lClean all disassembled parts in the designated liquid or sol-
vent prior to inspection or assembly.
lReplace oil seals, gaskets, packings, O-rings, locking
washers, cotter pins, self-locking nuts, etc. with new ones.
lReplace inner and outer races of tapered roller bearings and
needle bearings as a set.
lArrange the disassembled parts in accordance with their
assembled locations and sequence.
lDo not touch the terminals of electrical components which
use microcomputers (such as ECMs).
Static electricity may damage internal electronic compo-
nents.
lAfter disconnecting vacuum or air hoses, attach a tag to
indicate the proper connection.
lUse only the fluids and lubricants specified in this manual.
lUse approved bonding agent, sealants or their equivalents
when required.
lUse tools and recommended special tools where specified
for safe and efficient service repairs.

Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure fluid escaping from the
radiator.
Wrap a thick cloth around the cap. Slowly turn it a quarter turn
to allow built-up pressure to escape. Carefully remove the cap
by turning it all the way.

CHECKING COOLING SYSTEM FOR LEAKSNCLC0017S02
To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than specified may cause radiator damage.
CHECKING RADIATORNCLC0017S04
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 sur-
rounding parts such as cooling fan, radiator shroud and horns.
Then tape the harness and connectors to prevent water from
entering.
1. Apply water by hose to the back side of the radiator core ver-
tically download.
2. Apply water again to all radiator core surfaces once per
minute.
3. Stop washing if any stains no longer flow out from the radia-
tor.
4. Blow air into the back side of radiator core vertically download.

Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2,
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 RADIATOR CAPNCLC0017S03
To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Limit
59-98kPa
(0.59 - 0.98 bar, 0.6 - 1.0 kg/cm
2,9-14psi)
Pull the negative pressure valve to open it.
Check that it closes completely when released.

REMOVAL AND INSTALLATIONNCLC0018
CAUTION:

When removing water pump assembly, be careful not to
get coolant on drive belt.

Water pump cannot be disassembled and should be
replaced as a unit.

After installing water pump, and check for leaks using
radiator cap tester.
1. Drain coolant from radiator and cylinder block.
Refer to MA section (“Changing Engine Coolant”,“ENGINE
MAINTENANCE”).
2. Remove cylinder head front mounting bracket.
3. Remove drive belts and idler pulley.
4. Loosen water pump pulley bolts.
5. Remove water pump pulley.
6. Remove water pump bolts.
7. Remove water pump with gasket.
8. Reinstall parts in reverse order of removal.
