Remove the RH side front wheel.
(Refer to Suspension System - "Wheel")
Remove the engine room front under cover and RH side cover.
(Refer to Engine and Transaxle Assembly - "Engine Room Under Cover")
Remove the drive belt.
Loosen the alternator mounting bolts (A).
Loosen the tension by turning the tension adjusting bolt (B) counterclockwise.
Remove the drive belt (A).
Visually check the belt for excessive wear, frayed cords etc.
If any defect has been found, replace the drive belt.
Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should be replaced.
Measure the drive belt tension. if necessary, drive belt an adjust.
Measure the belt tension using a mechanical tension gauge or a sonic tension meter.
Tension
[With ISG (Idle Stop & Go) System]
New Belt :
1127.8 ~ 1225.8 N (115 ~ 125 kgf, 831.8 ~ 904.1 lbf)
Used Belt :
863.0 ~ 961.1 N (88 ~ 98 kgf, 636.5 ~ 708.8 lbf)
[With overrunning alternator decoupler(OAD)]
New Belt :
637.4 ~ 735.5 N (65 ~ 75 kgf, 470.1 ~ 542.5 lbf)
Used Belt :
490.3 ~ 588.3 N (50 ~ 60 kgf, 361.7 ~ 434.0 lbf)
[Without overrunning alternator decoupler(OAD)]
New Belt :
882.6 ~ 980.7 N (90 ~ 100 kgf, 651.0 ~ 723.3 lbf)
Used Belt :
686.5 ~ 784.5 N (70 ~ 80 kgf, 506.3 ~ 578.6 lbf)
While pressing the handle (A) of the gauge, insert the belt (B) between pulley and pulley (or idler) into the gap between spindle (C) and hook (D).
After releasing the handle (A), read a value on the dial pointed by the indicator (B).
Input the belt specifications into the tension meter (A).
Belt type | Location of measurement | Input data | ||
M (Mass, g/m.rib) | W (Width, rib) | S (Span, mm) | ||
With ISG (Idle Stop & Go) System and with A/C | Crankshaft pulley to A/C compressor pulley | 13.4 | 7 | 196 |
With ISG (Idle Stop & Go) System and without A/C | Idler to alternator pulley | 13.4 | 6 | 130 |
Without ISG (Idle Stop & Go) System and with A/C | Crankshaft pulley to A/C compressor pulley | 13.4 | 5 | 196 |
Without ISG (Idle Stop & Go) System and without A/C | Idler to alternator pulley | 13.4 | 5 | 123 |
Measurement of S (Span) : Caculate average value after measuring the distance 3~4 times.
Locate the micro phone (B) close to the center of belt span (A) and bounce the belt by finger 2~3 times. Read a value on the display.
[With A/C]
[Without A/C]
Loosen the mounting bolts (A).
Tighten the adjusting bolt (B) clockwise in loose tension ; loosen the bolt counterclockwise in high tension.
Recheck tension of the belt.
After adjusting tension, tighten the through bolts.
Tightening torque
12mm (0.47in) bolt :
26.5 ~ 32.3 N.m (2.7 ~ 3.3 kgf.m, 19.5 ~ 23.9 Ib-ft)
14mm (0.55in) bolt :
29.4 ~ 41.2 N.m (3.0 ~ 4.2 kgf.m, 21.7 ~ 30.4 Ib-ft)
Install the drive belt (A).
Adjust tension by tightening the alternator tension adjust bolt (B) and then install the mounting bolts (A).
Tightening torque
12mm (0.47in) bolt :
26.5 ~ 32.3 N.m (2.7 ~ 3.3 kgf.m, 19.5 ~ 23.9 Ib-ft)
