WATER PUMP/GENERATOR DRIVE BELT TENSION INSPECTION AND
ADJUSTMENT
1) Inspect belt for cracks, cuts, deformation, wear and cleanli-
ness. If it is necessary to replace belt, refer to “WATER
PUMP/GENERATOR DRIVE BELT” in this section.
2) Check belt for tension. Belt is in proper tension when it
deflects 4.5 to 5.5 mm (0.18 – 0.22 in.) under thumb pres-
sure (about 10 kg or 22 lb.).
Water pump / generator drive belt tension “a”
4.5 – 5.5 mm (0.18 – 0.22 in.) as deflection/10 kg (22 lbs)
3) If belt is too tight or too loose, adjust it to proper tension by
displacing generator position.
4) Tighten generator adjusting bolt and pivot bolts as specified
torque.
Tightening torque
Generator adjusting bolt (a) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
Generator pivot bolt (b) : 50 N·m (5.0 kg-m, 36.0 lb-ft)
5) Connect negative cable at battery. WARNING:
Disconnect negative cable at battery before checking and adjusting belt tension.
To help avoid danger of being burned, do not remove radiator cap while engine and radiator are still
hot. Scalding fluid and steam can be blown out under pressure if cap is taken off too soon.
NOTE:
When replacing belt with a new one, adjust belt tension
to 3 – 4 mm (0.12 – 0.16 in.).

TOR DRIVE BELT TENSION INSPECTION AND ADJUST-
MENT” in this section.
For adjustment of compressor drive belt tension, refer to
COMPRESSOR DRIVE BELT in Section 1B.
3) Tighten water pump belt adjusting bolt and pivot bolt to spec-
ified torque.
Tightening torque
Generator adjusting bolt (a) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
Generator pivot bolt (b) : 50 N·m (5.0 kg-m, 36.0 lb-ft)
4) Connect negative cable at battery.

GENERAL DESCRIPTION
The main components of the fuel system are fuel tank, fuel pump assembly (with fuel filter, fuel level gauge, fuel
pressure regulator and tank pressure control valve), fuel/vapor separator fuel feed line and fuel vapor line.
For the details of fuel flow and fuel vapor flow, refer to “GENERAL DESCRIPTION” in Section 6E. WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
CAUTION:
The engine of this vehicle requires the use of unleaded fuel only. Use of leaded and/or low lead fuel
can result in engine damage and reduce the effectiveness of the emission control system.
