7–20 SERVICE AND VEHICLE CARE
To check the drive belt tension, do the
following:
1. Apply moderate thumb pressure (ap-
proximately 10 kgf) midway along
the longest, unsupported span of the
drive belt.
The deflection of the drive belt (caused
by your thumb pressure) should be
about 10 mm.
2. If the belt is too loose, see your
CHEVROLET retailer for service.
See the Maintenance Schedule for more
information.
BATTERY

nance-free battery.
Battery acid can cause severe burns,

CLEANING THE BATTERY TERMINALS
1. Turn the ignition OFF and remove the
key from the ignition key slot.
2. Use a wrench to loosen and remove the
battery cable clamps from the terminals.
Always disconnect the negative (-) ter-
minal first.
3. Use a wire brush or a terminal cleaning
tool to clean the terminals.
4. Check the battery terminals for white or
bluish powder, which are signs of cor-
rosion.
5. Remove any corrosion with a solution
of baking soda and water. The baking
soda-and-water solution will bubble
and turn brown.
6. When the bubbling stops, wash the
solution off with plain water and dry the
battery with a cloth or paper towel.
7. Reconnect and tighten the positive (+)
terminal, then the negative (-) terminal.
Always reconnect the negative termi-
nal (-) last.
