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 cracking, fraying or wear is found.
2. Check the front side belt tension and adjust it if necessary by adjusting the generator installing position.
Front side belt tension (when using a belt tension gauge):
When installing new parts
640 — 780 N (65 — 80 kgf, 144 — 175 lbf)
At inspection
490 — 640 N (50 — 65 kgf, 110 — 144 lbf)
|
(A) |
Front side belt |
|
(B) |
Rear side belt |
|
C/P |
Crank pulley |
|
GEN |
Generator pulley |
|
P/S |
Power steering oil pump pulley |
|
A/C |
A/C compressor pulley |
Front side belt tension (when not using a belt tension gauge):
When installing new parts
7 — 9 mm (0.276 — 0.354 in)
At inspection
9 — 11 mm (0.354 — 0.433 in)
|
(A) |
Front side belt |
|
(B) |
Rear side belt |
|
(C) |
98 N (10 kgf, 22 lbf) |
|
C/P |
Crank pulley |
|

If cracks, fraying or wear is found, and when abnormal noise is produced, replace the rear side belt.
NOTE:
Because the rear side belt is a stretch type belt, it is not necessary to check deflection and tension.
