Kia Cee'd: Timing System / Drive Belt Repair procedures
| 1. |
Disconnect the battery negative terminal.
|
| 2. |
Loosen the alternator tension adjusting bolt (A) to loosen tension.
|
| 3. |
Remove the drive belt (A).
|
Drive Belt Inspection
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
Measure the belt tension using a mechanical tension gauge or a sonic tension
meter.
|
Tension
New belt: 686.5 ~ 784.5N (70 ~ 80kg, 154.3 ~ 176.4lb)
Used belt: 490.3 ~ 588.4N (50 ~ 60kg, 110.2 ~ 132.3lb)
|
| • |
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.

| If adjustment is necessary: |
| 1. |
Loosen the mounting bolts (A).
|
| 2. |
Tighten the adjusting bolt(B) clockwise in loose tension ; loosen the
bolt counterclockwise in high tension.
|
| 3. |
Recheck tension of the belt.
|
| 4. |
After adjusting tension, tighten the through bolts.

|
|
| 1. |
Install the drive belt (A).
|
| 2. |
Adjust tension by tightening the alternator tension adjust bolt (B)
and then install the mounting bilts(A).
|
