INSPECTION AND MAINTENANCE

Drive belt
Check that the drive belt tension is correct.
If the belt is too loose, insufficient battery
charging, engine overheating, poor power
steering, poor air conditioning, or exces-
sive belt wear can result. When you press
the belt with your thumb midway between
the pulleys, there should be a deflection
according to the following chart.
The belts should also be examined to
ensure that they are not damaged.
If you need to replace or adjust the belt,
have it done by your SUZUKI dealer.
K12C and K12D engine models
