8. Repeat steps 1 through 7 until clear water begins to drain from radiator.
Checking Fuel LinesALS000GS
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
Changing Air Cleaner FilterALS000GT
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning between replacement intervals. Refer to MA-7,
"PERIODIC MAINTENANCE" .

CLEANER AND AIR DUCT" .
2. Remove air cleaner filter from air cleaner case.
Changing Engine OilALS000H7
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up engine, put vehicle horizontally and check for engine oil leakage from engine components. Refer to LU-25, "

PRECAUTIONS
Revision: 2005 July 2005 FX
PRECAUTIONSPFP:00001
CautionsAES000MF

When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

Unladen conditions means that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

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

Caulking nuts are not reusable. Always use new ones when installing. Since new caulking nuts are pre-
oiled, tighten as they are.

On-Vehicle Inspection and ServiceAES000MJ
Make sure the mounting conditions (looseness, back lash) of each component and component status (wear,
damage) are normal.
INSPECTION OF SUSPENSION ARM BALL JOINT END PLAY
Measure axial end play by installing and moving up/down between suspension arm and axle with an iron pry
bar or something similar.
CAUTION:
Be careful not to damage ball joint boot.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace if necessary.
Wheel Alignment InspectionAES000MK
DESCRIPTION
Measure wheel alignment under unladen conditions. “Unladen conditions” mean that fuel, engine coolant, and
lubricant are full. Spare tire, 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.
3. Check wheel bearing axial end play.
4. Check suspension arm ball joint axial end play.
5. Check shock absorber operation.
6. Check each mounting part of axle and suspension for looseness and deformation.
7. Check each link, arm and member for cracks, deformation, and other damage.
8. Check vehicle posture.
CAMBER INSPECTION
Measure camber of both right and left wheels with a suitable align-
ment gauge and adjust in accordance with the following procedures.
If outside the standard value, adjust with adjusting bolt in front lower
link.
NOTE:
After adjusting camber, be sure to check toe-in. Axial end play : 0 mm (0 in)
Camber : Refer to RSU-18, "
Wheel Alignment" .
