ENGINE LUBRICATION
The oil pump is of a trochoid type, and mounted on the crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into 2 paths in cylinder block.
In one path, oil reaches the crankshaft journal bearings. Oil from the crankshaft journal bearings is supplied to
the connecting rod bearings by means of intersecting passages drilled in the crankshaft, and then injected from
the big end of connecting rod to lubricate piston, rings, and cylinder wall.
In other path oil goes up to the cylinder head and lubricates valves and camshafts, etc., after passing through
the internal oilway of camshafts.
An oil relief valve is provided on the oil pump. This valve starts relieving oil pressure when the pressure exceeds
about 400 kPa (4.0 kg/cm
2, 56.9 psi).

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.
