The belt should deflect approx. 7.5
Proper mm (0.30 in.) when the belt (7) at the
alternator drive center of the checking belt window is
belt tension depressed with finger pressure of 98
N (10 kgf, 22 lbs.).
5. Fasten the M10 bolt.
6. Check that the deflection of the belt at the center of the
checking belt window is proper as the fourth step of the
checking procedure.
A Make sure to check the deflection of the belt after
fastening the M10 bolt.
7. If the deflection of the belt is incorrect, restart the work
from the third step of the adjusting procedure.
8. Fasten the M8 bolt.
9. Fix the lock nut.
[If equipped with the belt cover with no checking belt
cover; the first 2 digits of the engine serial number are
8L, 8N, or 8Q.]
C Checking procedure
1. Park the vehicle on a flat surface.
2. Stop the engine and remove the key.
3. Remove three M6 bolts, and then remove the belt
cover.
4. First of all, apply finger pressure of 98N (10 kgf, 22
lbs.) to the center of the belt between pulleys as shown
in the figure.
5. Repeat step 4. to measure the belt tension.
6. If the deflection of the belt is over the prescribed value,
the alternator drive belt should be adjusted.
7. Replace the alternator drive belt if it is damaged.
8. Make sure to set the belt cover again in place with the
M6 bolts after checking.
