Service Precaution

WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING, REFER TO
THE SRS SERVICE INFORMATION. FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fastener. When
you install fasteners, use the correct tightening
sequence and specifications. Following these
instructions can help you avoid damage to parts and
systems.

ENGINE LUBRICATION (Y22SE 2.2L)

General Description

A gear type oil pump is derectly driven by the crankshaft
and draws oil from the oil pan, via the suction pipe. The oil
pressure created allows the oil to flow through the oil filter
into the main oil gallery in the cylinder block.  An oil pump
pressure relief valve and oil filter bypass valve are
incorporated in the system.
From the main oil gallery in the cylinder block, the cylinder
head and crankshaft main bearings are supplied with oil.

The camshaft bearings and hydraulic tappets are
supplied through the main feed galleries in the cylinder
head.  Vent valves allow air to be expelled from the oil
galleries in the cylinder head.  The balance shaft journals
are directly fed from the crankshaft main bearings.  The
connecting rod bearings are fed via passages in the
crankshaft.  The oil returns to the oil pan via passages in
the cylinder block.
