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.
NOTE:
Since the rear belt is a stretch type belt, it does not require tension check and adjustment.
1. PROCEDURE (WITHOUT BELT TENSION GAUGE)
1. Replace the belts if cracks, fraying or wear are found.
2. Check the V-belt tension and adjust it if necessary by adjusting the generator installing position. 
Belt tension (force of 98 N (10 kgf, 22 lbf) is applied)
When installing new parts: 7 — 9 mm (0.276 — 0.354 in)
At inspection: 9 — 11 mm (0.354 — 0.433 in)

2. PROCEDURE (WITH BELT TENSION GAUGE)
1. Replace the belts if cracks, fraying or wear are found.
2. Remove the V-belt covers and radiator reservoir tank.
3. Check the belt tension, using the belt tension gauge. Adjust the tension if necessary by adjusting the installation position of the generator.
