Second generation YD (2014-2018) / Kia Forte TD 2014-2018 Service Manual / Engine Mechanical System / Timing System / Drive Belt Inspection

1.
Check belt for maintenance and abnormal wear of V-ribbed part. Replace if necessary.
  
•
Do not bend, twist or turn the drive belt inside out.
•
Do not allow the drive belt to come into contact with oil, water and steam.
2.
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.

Drive belt tension measurement and adjustment
Belt tension measurement
Measure the belt tension using a mechanical tension gauge or a sonic tension meter.
Belt tension
New belt:
637.4 ~ 735.5 N (65 ~ 75 kgf, 143.3 ~ 165.3 lbf)
Used belt:
441.3 ~ 539.4 N (45 ~ 55 kgf, 99.2 ~ 121.3 lbf)
  
•
If the engine has run for 5 minutes or more, the belt tension must be adjusted as a used belt.
•
When installing the V-ribbed belt, all grooves on the pulley should be covered with belt ribs.
•
A loose belt causes slip noise.
•
Too tight belt cause bearing of alternator and water pump to damage.
Using a mechanical tension gauge
1.
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).
2.
After releasing the handle (A), read a value on the dial pointed by the indicator (B).

Using a sonic tension meter
1.
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 A/C
 Crankshaft pulley to A/C compressor pulley
14.7
 006.0
 187
Without A/C
 Crankshaft pulley to alternator pulley

 Actual measurement value

  
Measurement of S (Span): Caculate average value after measuring the distance 3~4 times.

2.
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]
If adjustment is necessary:
1.
Loosen the mounting bolts (A).
2.
Tighten the adjusting bolt (B) counterclockwise in loose tension; fasten the bolt clockwise in high tension.
3.
Recheck tension of the belt.
4.
After adjusting tension, tighten the mounting bolts.
Tightening torque
M10 bolt:
29.4 ~ 41.2 N.m (3.0 ~ 4.2 kgf.m, 21.7 ~ 30.4 Ib-ft)
M8 bolt:
21.6 ~ 32.4 N.m (2.2 ~ 3.3 kgf.m, 15.9 ~ 23.9 Ib-ft)
