CheckingINFOID:0000000005930924
• 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 times clockwise, and make sure 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 acous tic tension gauge 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 ad just it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the sp ecified value to avoid variation in deflection
between pulleys.
Tension AdjustmentINFOID:0000000005930925
CAUTION:
• When belt is replaced with new one, adjust belt te nsion 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, make sure 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.
1. Loosen the idler pulley lock nut (A) from the tightening position with the specified torque by 45 degrees.

DRIVE BELTS
• When the lock nut is loosened
excessively, the idler pulley tilts an d the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
• Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt. CAUTION:
• When checking immediately after in stallation, 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 deflec-
tion between pulleys.
• When the tension adjustment is performed, the lo ck nut should be in the condition at step“2”. If
the tension adjustment is performed when the lo ck nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
Removal and InstallationINFOID:0000000005930926
REMOVAL
1. Loosen the idler pulley lock nut (A), and then adjust the belt ten- sion by turning the adjusting bolt (B).
2. Remove drive belt.
INSTALLATION
1. Pull the idler pulley in the loosening direction, and then tempo- rarily tighten the idler pulley lock nut (A) to the following torque.
NOTE:
Do not move the lock nut from t he tightened position. Proceed to step “2”.
2. Install the drive belt to each pulley. CAUTION:
• Make sure that there is no oil, greas e, or coolant, etc. in pulley grooves.
• Make sure that the belt is securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-13, "
Tension Adjustment".

WARNING:
Be sure to perform this step
when the engine is stopped.
NOTE:
On vehicles not equipped with A/C, there is an idler pulley in the position for the drive belt routing.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range.
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range.
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of t he possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000005930999
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000005931000
REMOVAL
1. Remove fender protector (RH). Refer to EI-26, "Removal and Installation".
2. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
WARNING:
Never place hand in a location where pinching may occur if
the holding tool acci dentally comes off.
CAUTION:
Do not loosen the auto-tensione r pulley bolt. (Do not turn it
counterclockwise.) If turned counterclockwise, the com-
plete auto-tensioner must be replaced as a unit, including
pulley.
3. Insert a rod such as short-length screwdriver approximately 6 mm (0.24 in) in diameter into the hole (B) of t he retaining boss to fix drive belt auto-tensioner.
• Leave tensioner pulley arm locked until belt is installed again.
4. Remove drive belt.

5. Remove idler pulley and bracket (models without A/C).
CAUTION:
Do not loosen the auto-tensioner pulley bolt. (Do no t turn it counterclockwise). If turned counter-
clockwise, the complete auto-tensioner must be replaced as a unit, including pulley.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When installing drive belt auto-tensioner, be careful not to interfere with water pump pulley.
• If there is damage greater than peeled paint, re place drive belt auto-tensioner and/or idler pulley, if
equipped.
• Install the drive belt auto-t ensioner carefully so not to damage the water pump pulley.
• Do not swap the pulley between the new and old auto-tensioner units
