16) Make sure that the belt rib is securely installed on the groove of each pulley, then turn the crank pulley slowly, twice in the clockwise direction, to

INSPECTION
FRONT SIDE BELT
CAUTION:
Check and adjust the front side belt tension so that it is within the specified range. Using the belt with a tension out of the specified range
may result in a fault such as the following:
-
If the front side belt tension is higher, unexpected force is generated at the power steering oil pump, generator and crankshaft bearing,
causing abnormal noise due to abnormal wear of the bearing.
-
If the front side belt tension is lower, the front side belt and crank pulley slip, causing abnormally high temperature on the crank pulley
due to frictional heat. If this condition repeatedly occurs, the front side belt may abnormally wear, causing abnormal noise, front side belt
damage or crank pulley damage.
1) Replace the front side belt, if crack, fraying or wear is found.
2) Check the front side belt tension and adjust it if necessary by changing the generator installing position.
