WARNING: IF SO EQUIPPED WITH 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.

manual.
5. Remove Idle pulley.
6. Remove water pump assembly.
7. Remove gasket.
Inspection
Make necessary repair and parts replacement if extreme
wear or damage is found during inspection. Should any of
the following problems occur, the entire water pump
assembly must be replaced:
Crack in the water pump body
EC leakage from the seal unit
Play or abnormal noise in the bearing

Inspection
Suspend the thermostat in a water–filled container using
thin wire. Place a thermometer next to the thermostat.
Do not directly heat the thermostat.
Gradually increase the water temperature. Stir the water
so that the entire water is same temperature.

1. Install thermostat into the outlet pipe(4) making sure
that the air hole is in the up position.
2. Install thermostat housing and tighten bolts to the
specified torque.

Inspection
Check drive belt for wear or damage, and replace with a
new one as necessary.
Installation
Install cooling fan assembly and tighten bolts/nuts to the
specified torque.
Torque : 22 Nꞏm (2.2 Kgꞏm/16 lb ft) for fan pulley
and fan bracket.
Torque : 10 Nꞏm (1.0 Kgꞏm/88.5 lb in) for fan and
clutch assembly.
NOTE: Fan belts for 6VE1 Gasoline Engine mounted on
98MY (UX) have been brought into one. As a result, the
rotating direction of a fan belt is opposite to the direction

interchangeability.
Therefore, incorrect installation of a fan may cause the air
for cooling to flow in the opposite direction, this resulting
in the poor performance of the air-conditioner and a rise
temperature in engine cooling water.
