DRIVE BELT
DRIVE BELT : Checking
INFOID:0000000006479321
• Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
• Visually check belts for wear, damage, and cracks on inside and
edges.
• Turn crankshaft pulley two time clockwise, and check tension on all pulleys is equal before doing the test.
• When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
• Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
• When the tension and frequency are measured, the acoustic tension gauge should be used.
• When checking immediately after installation, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, readjust to the specified value to avoid variation in deflection between
pulleys.
DRIVE BELT : Tension Adjustment
INFOID:0000000006479322
CAUTION:
• When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
• When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
• When installing a belt, check it is correctly engaged with the pulley groove.
• Never allow oil or engine coolant to get on the belt.
• Never twist or bend the belt strongly.

• When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
• Put a matching mark on the lock nut (A), and check turning angle with a protractor. Never visu-
ally check the tightening angle.
3.
Adjust the belt tension by turning the adjusting bolt (B). Refer to

.
CAUTION:
• When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflec-
tion between pulleys.
• When the tension adjustment is performed, the lock nut should be in the condition at step“ 2”. If
the tension adjustment is performed when the lock nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.

Close the air relief plug and run the engine at 2,000 rpm until the upper hose comes hot and radiator fan
operates. Let the engine running approximately 5 minutes at idle speed and check for sound of coolant
flow while running engine from idle up to 3,000 rpm.
• Sound may be noticeable at heater water cock.
6.
If sound is heard, bleed air from cooling system by repeating steps 4 through 5 until coolant level no
longer drops.
• Check the radiator lower hose for any signs of leakage.
7.
Turn off the engine and let it cool down.
• Cool down using a fan to reduce the time.
8.
After cooling period, loose the air relief plug and check if coolant spills from the air relief hole. In other
case, remove the air relief plug until the coolant spills, and then close the relief air plug. Bleed air from
cooling system by repeating steps 5 through 8 until the coolant spills immediately.
