ENGINE MAINTENANCE
Deflection Adjustment
ELS001JP
lAdjust belts with the parts shown below.
CAUTION:
lWhen a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.
lIf the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
lWhen checking belt tension immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.
lMake sure the belts are fully fitted into the pulley grooves during installation.
lHandle with care to avoid smearing the belts with engine oil or engine coolant.
lDo not twist or bend the belts with strong force.

LINING
lCheck for lining thickness.
Checking Steering Gear and LinkageELS001J3
STEERING GEAR
lCheck the steering gear housing for looseness, damage and oil
leakage as shown.
lCheck the steering column connections for looseness.
STEERING LINKAGE
lCheck the ball joint, dust cover and other component parts for looseness, wear, damage and grease leak-
age.
Checking Power Steering Fluid and LinesELS001J4
CHECKING FLUID LEVEL
lCheck the power steering fluid level with the engine off.
lCheck fluid level on reservoir. Use “HOT” range at fluid tempera-
tures of 50°to 80°C(122°to 176°F). Use “COLD” range at fluid
temperatures of 0°to 30°C(32°to 86°F).
CAUTION:
lDo not overfill.
lFill with the recommended fluid or equivalent. Refer toMA-
14, "Fluids and Lubricants".
CHECKING LINES
lCheck lines for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.Standard thickness : 5.5 mm (0.22 in)
Repair limit thickness : 1.5 mm (0.66 in)
