[3] COOLING SYSTEM
(1) Checking and Adjusting
Fan Belt Tension
1. Measure the deflection
(A)
, depressing the belt halfway between
the fan drive pulley and alternator at specified force (98 N, 10 kgf,
22 lbs).
2. If the measurement is not within the factory specifications, loosen
the alternator mounting screws and relocate the alternator to
adjust.
W10384280
Fan Belt Damage and Wear
1. Check the fan belt for damaged.
2. If the fan belt is damaged, replace it.
3. Check if the fan belt is worn and sunk in the pulley groove.
4. If the fan belt is nearly worn out and deeply sunk in the pulley
groove, replace it.

CAUTION
• When removing the radiator cap, wait at least ten minutes after the engine has stopped and cooled down.
Otherwise, hot water way gush out, scalding nearby people.
Radiator Cap Air Leakage
1. Set a radiator tester (Code No. 07909-31551) and an adapter
(BANZAI Code No.RCT-2A-30S) on the radiator cap.
2. Apply the specified pressure (88 kPa, 0.9 kgf/cm
2
, 13 psi), and
measure the time for the pressure to fall to 59 kPa (0.6 kgf/cm
2
,
9 psi).
3. If the measurement is less than the factory specification, replace
the radiator cap.
W10387530
Radiator Water Leakage
1. Pour a specified amount of water into the radiator.
2. Set a radiator tester (Code No. 07909-31551) with an adapter
(BANZAI Code No.RCT-2A-30S) and raise the water pressure to
the specified pressure.
3. Check the radiator for water leaks.
4. For water leak from the pinhole, replace the radiator or repair with
the radiator cement. When water leak is excessive, replace the
radiator.
