On-Vehicle Inspection

Check the electrolyte quantity of each cell.

Maintenance-Free Battery: If under the lower level, replace the battery (or add distilled water if possible). Check the charging system.

Except Maintenance-Free Battery: If under the lower level, add distilled water.

Check the specific gravity of each cell.

Standard specific gravity  : 1.25-1.29 at 20°C (68°F)

If the specific gravity is less than specification, charge the battery.

1. After having driven the vehicle and in the case that 20 minutes have not passed after having stopped the engine, turn the ignition switch ON and turn on the electrical system (headlight, blower motor, rear defogger etc.) for 60 seconds to remove the surface charge.
2. Turn the ignition switch OFF and turn off the electrical systems.
3. Measure the battery voltage between the negative (-) and positive (+) terminals of the battery.

   Standard voltage  : 12.5-12.9 V at 20°C (68°F)

   If the voltage is less than specification, charge the battery.

1. Check that the battery terminals are not loose or corroded.

   If the terminals are corroded, clean the terminals.

2. Check the fusible link, H-fuses, M-fuse and fuses for continuity.

1. Visually check the drive belt for excessive wear, frayed cords etc.

   If any defect has been found, replace the drive belt.

   NOTE:

   • Cracks on the rib side of a drive belt are considered acceptable. If the drive belt has chunks missing from the ribs, it should be replaced.
   • The drive belt tension can be released by turning the belt tensioner counterclockwise. The pulley bolt for the belt tensioner has a left-hand thread.

2. Check the belt tensioner operation.
   1. Check that the belt tensioner moves downward when the drive belt is pressed down at the points indicated in the illustration with approx. 98 N (10 kgf, 22.0 lbf) of force.
   2. Check the alignment of the belt tensioner pulley to make sure the drive belt has not slipped off the pulley.

      If necessary, replace the belt tensioner.

   3. Check that the arrow mark is positioned on the left of line A.

      If not, replace the drive belt.
