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, REFE
R
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, o
r
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.

6B-2 ENGINE COOLING (6VE1 3.5L)
General Description
030RW001
Legend (7)Cylinder Head
(1) Water Pump (8) Right Bank
(2) Thermostat (9) Throttle Body
(3) Radiator (10) Cylinder Block
(4) Reserve Tank (11) Cylinder Head
(5) Cooling Fan (12) Left Bank
(6) Cylinder Block (13) Heater
The engine cooling system consists of the radiator, the
water pump, the cooling fan, and the thermostat.
To quickly increase cold engine coolant temperature fo
r
smooth engine operation, the coolant is circulated by
the water pump and thermostat through the bypass
hose and back to the cylinder body.
The coolant does not circulate through the radiator.
When the coolant temperature reaches specified value,
the thermostat will begin to open and a gradually
increasing amount of coolant will circulate through the
radiator.
The thermostat will be fully open when the coolan
t
temperature reaches specified value. All of the coolant
is now circulating through the radiator for effective
engine cooling.

ENGINE COOLING (6VE1 3.5L) 6B-3
Water Pump
The EC pump is a centrifugal impeller type and is driven
by a timing belt.
030RS001
Thermostat
The thermostat is a wax pellet type with a air hole(1)
and is installed in the thermostat housing.
031RW002
Radiator
The radiator is a tube type with corrugated fins. In order
to raise the boiling point of the coolant, the radiator is
fitted with a cap in which the valve is operated at 93.3
122.7 kPa (13.5 17.8 psi) pressure. (No oil cooler
provided for M/T)

See section 0B MAINTENACE AND LUBRICATION.
Mixing ratio
NOTE: To maintain the corrosion resistance of the
aluminum radiator, water and antifreeze must be
combined in a 1:1 solution (50% antifreeze and 50%
water).
