SERVICE AND MAINTENANCE
ADVICE
• Battery fluid should never be filled beyond the "UPPER LEVEL" line. Failure
to observe this precaution can result in battery fluid spillage and corrosion of
battery terminals and other components. Any spilled battery fluid should be
immediately washed away with water.
• Whenever battery fluid has been added, the battery should be recharged (by
driving the vehicle). In winter months in particular, battery fluid can freeze and
damage the battery case if you fail to recharge the battery.
• If the battery fluid level continues to drop at an unusually fast rate, have an
inspection carried out immediately by the nearest Isuzu Dealer.
Checking the Specific Gravity of Battery Fluid
Checking the Battery Fluid Level
1. Check to see if the fluid surface is
between the "UPPER" and "LOWER"
levels. If it is, the fluid level is correct.
If no level marks are indicated on
the case, a range between 10 and
15 mm (0.39 to 0.59 in) from the top
of the battery plates is considered
appropriate.
2. If there is an insufficient amount of
fluid, remove the caps from the filler
ports and add top-up fluid or distilled
water.
1. Check the specific gravity of the
battery fluid using a hydrometer. If the
specific gravity is too low, the battery
should be charged.
