ENGINE
INSPECTION
HINT:
Perform the following procedures when the engine is cold.
1. REPLACE TIMING BELT
(See page EM±13)
2. INSPECT DRIVE BELT
(See page CH±1)
3. REPLACE SPARK PLUGS
(See page IG±1)
4. INSPECT AIR FILTER
(a) Visually check that the air cleaner element is not exces-
sively dirty, damaged or oily.
HINT:
Oiliness may indicate a stuck PCV valve.
If necessary, replace the air cleaner element.
(b) Clean the element with compressed air.
First blow from back side thoroughly, then blow off the
front side of the element.
5. REPLACE AIR FILTER
Replace the used air cleaner element with a new one.
6. REPLACE ENGINE OIL AND OIL FILTER
(See page LU±2)
7. REPLACE ENGINE COOLANT
(See page CO±2)
8. INSPECT CHARCOAL CANISTER
(See page EC±9)
9. REPLACE GASKET IN FUEL TANK CAP
(See page SF±33)
10. INSPECT FUEL LINES, CONNECTIONS, FUEL TANK
VAPOR VENT SYSTEM HOSES AND FUEL TANK
BAND
Visually inspect the fuel lines for cracks, leakage loose connec-
tions, deformation or tank band looseness.
11. INSPECT EXHAUST PIPES AND MOUNTINGS
Visually inspect the pipes, hangers and connections for severe
corrosion, leaks or damage.
12. INSPECT VALVE CLEARANCE
(See page EM±4)

BRAKE
INSPECTION
1. INSPECT BRAKE LINE PIPES AND BOOTS
HINT:
Inspect in a well±lighted area. Inspect the entire circumference
and length of the brake hoses using a mirror as required. Turn
the front wheels fully right or left before inspecting the front
brake.
(a) Check all brake lines and hoses for:

Damage

Wear

Deformation

Cracks

Corrosion

Leaks

Bends

Twists
(b) Check all clamps for tightness and connections for leak-
age.
(c) Check that the hoses and lines are clear of sharp edges,
moving parts and the exhaust system.
(d) Check that the lines installed in grommets pass through
the center of the grommets.
2. INSPECT FRONT AND REAR BRAKE PADS AND
DISCS
(Front pads: See page BR±25)
(Rear pads: See page BR±34)
HINT:
If a squealing or scraping noise occurs from the brake during
driving, check the pad wear indicator.
If there are traces of the indicator contacting the disc rotor, the
disc pad should be replaced.

INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel free play (See page SR±9).
(b) Check the steering linkage for looseness or damage.
Check that:

Tie rod ends do not have excessive play.

Dust seals are not damaged.

Boot clamps are not loose.
2. INSPECT SRS AIRBAG (See page RS±3)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leaks.
If leakage is found, check the cause and repair.
4. 4WD:
INSPECT DRIVE SHAFT BOOTS
Inspect the drive shaft boots for clamp looseness, grease leak-
age or damage.
5. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(b) Inspect the dust cover for damage.
6. 2WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION
AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.
