Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter
of a turn to release built-up pressure. Then turn the cap all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR CAP

Check valve seat of radiator cap.
–Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
–Check if valve seat has no soil and damage.

Pull negative-pressure valve to open it, and make sure that it is
completely closed when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

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 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 that engine coolant decreases, replenish radiator with engine coolant.

If anything is found, repair or replace damaged parts.
Checking Fuel LinesBLS00094
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 FilterBLS00095
VISCOUS PAPER TYPE
The viscous paper type filter does not need cleaning between replacement intervals. Refer to MA-8,
"PERIODIC MAINTENANCE".
Removal
1. Unhook air cleaner case (lower) side clips and lift up air cleaner case (upper).
2. Remove air cleaner filter.

Checking Drive BeltsBLS0005J
WARNING:
Be sure to perform the following when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection at a point on the belt midway
between pulleys.

Inspection should be done only when engine is cold, or over
30 minutes after engine is stopped.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.

Adjust if belt deflection exceeds the limit.
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified
value to avoid variation in deflection between pulleys.

Release the tension by loosing lock nut and turning adjust-
ing bolt when adjusting the belt. Tighten once the lock nut
at 4.9 N·m (0.50 Kg-m, 43 in-lb). Then, adjust the belt ten-
sion by loosing lock nut between 45° and 90°.
Belt Deflection
Tension AdjustmentBLS0005K
CAUTION:

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

When deflection of belt being used exceeds “Limit”, adjust it to value for “After adjustment”.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid variation
in deflection between pulleys.

When installing belt, make sure that it is correctly engaged with pulley groove.

Keep engine oil, working fluid and engine coolant away from belt.

Do not twist or bend belt excessively.
