Inspection
Radiator Cap
Measure the valve opening pressure of the pressurizing
valve with a radiator filler cap tester.
Replace the cap if the valve opening pressure is outside
the standard range.
Valve opening pressure kPa (psi) 93.3






122.7
(13.5






17.8)
Cap tester: 5 –8840 –0277 –0
Adapter: 5 –8840 –2603 –0
Check the condition of the vacuum valve in the cente
r
of the valve seat side of the cap. If considerable rust or
dirt is found, or if the valve seat cannot be moved by
hand, clean or replace the cap.

7. Connect battery ground cable.
8. Pour engine coolant up to filler neck of radiator, and
up to MAX mark of reserve tank.




RTW36BSH000101
Important operation (in case of 100% engine
coolant change) procedure for filling with engine
coolant.

Engine coolant change
1. To change engine coolant, make sure that the
engine is cool.
WARNING: When the coolant is heated to a high
temperature, be sure not to loosen or remove the
radiator cap. Otherwise you might get scalded by
hot vapor or boiling water. To open the radiato
r
cap, put a piece of thick cloth on the cap and
loosen the cap slowly to reduce the pressure when
the coolant has become cooler.
2. Open radiator cap and drain the cooling system by
loosening the drain valve on the radiator and on the
cylinder body.
NOTE: For best result it is suggested that the engine
cooling system be flushed at least once a year. It is
advisable to flash the interior of the cooling system
including the radiator before using anti-freeze
(ethylene-glycol based).
Replace damaged rubber hoses as the engine
anti-freeze coolant is liable to leak out even mino
r
cracks.
Isuzu recommends to use Isuzu genuine anti-freeze
(ethylen-glycol based) or equivalent, for the cooling
system and not add any inhibitors or additives.
CAUTION: A failure to correctly fill the engine
cooling system in changing or topping up coolant
may sometimes cause the coolant to overflow from
the filler neck even before the engine and radiato
r
are completely full.
If the engine runs under this condition, shortage o
f
coolant may possibly result in engine overheating.
To avoid such trouble, the following precautions
should be taken in filling the system.
3. To refill engine coolant, pour coolant up to filler neck
using a filling hose which is smaller in outside
diameter of the filler neck. Otherwise air between
the filler neck and the filling hose will block entry,
preventing the system from completely filling up.
4. Keep a filling rate of 9 liter/min. or less. Filling ove
r
this maximum rate may force air inside the engine
and radiator.
And also, the coolant overflow will increase, making
it difficult to determine whether or not the system is
completely full.
5.
After filling the system to the full, pull out the filling
hose and check to see if air trapped in the system is
disclodged and the coolant level goes down. Should
the coolant level go down, repeat topping-up until
there is no more drop in the coolant level.

Removal
CAUTION: When repair to the fuel system has been
completed, start engine and check the fuel system
for loose connection or leakage. For the fuel system
diagnosis, see Section “Driveability and Emission".
1. Remove fuel tank assembly (9). Refer to “Fuel
Tank Removal" in this section.
2. Disconnect the quick connector (6) into the fuel
tube from fuel pump.
3. Disconnect the quick connector (10) into the evapo
tube from fuel pump.

3. Remove the retainer ring (7) from the fuel tank
with the removal tool 5-8840-2602-0.

4. Remove slowly the fuel pump (4) from the fuel
tank as no bend float arm.
NOTE: Cover opening for the fuel pump on fuel tank to
prevent any dust enthering.
5. Discard fuel pump seal (8) because it cannot be
reusable.
Installation
1. Clean the seal surface of the fuel tank and the fuel
pump.
NOTE: If there is dust on the seal surface, it becomes
cause of fuel leak.
2. Install the new fuel pump seal (8) to opening of the
fuel tank as along the groove.
3. Install slowly the fuel pump (4) into the fuel tank as
no bend float arm.
4. Set flange of the fuel pump on fuel pump seal as
mating convexity of the fuel pump and reentrant o
f
the fuel tank.
5. Lock slowly the retainer ring (7) to the fuel tank
with the remover tool 5-8840-2602-0.
6. Connect the quick connector (10) into the evapo
tube to fuel pump.
7. Connect the quick connector (6) into the fuel tube
to fuel pump.
NOTE: Pull off the left ckecker into the fuel pipe.
NOTE: Refer to “Fuel Tube/Quick Connector Fittings” in
this section when performing any repairs.

8. Check leak.
Methed of leak check.
(1) Plug end of quick connector and breather hose
(Pull off the breather hose from fuel tank) and
tighten fuel filler cap until at least one click are
heard.
(2)
Apply water soap around the fuel pump seal
area.
(3) Pressure air into the fuel tank from end o
f
breather pipe at 5psi (34.3 kPa/2.8kgf/cm2)
over 15 seconds.
(4) Verify no bubbles around the fuel pump seal
area.
8. Install the fuel tank assembly (9).
NOTE: Refer to “Install the fuel tank” in this section.

Reuse of Quick–Connector
 Replace the port and connector if scratch, dent or
crack is found.
 Remove any dirt build up on the port when installing
the connector. Replace the connector, if there is any
forms of rust, dent, scratch.
 After cleaning the port, insert it straight into the
connector until it clicks. After it clicks, try pulling a
t
49N (5kgf) it out to make sure that it is not drawn
and is securely locked.

Assembling Advice
By applying engine oil or light oil to the pipe, port makes
pipe assembly easier. The pipe assembly should take
place immediately after applying oil (to prevent dus
t
from sticking to the pipe surface –which may
decrease sealing ability).
Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the “ON" position and listen
for pump start-up sound. Inspect for leaks, the
fuel pressure will increase as the fuel pump is
actuated.
3. Perform leak inspection (step 2) several times.
4. Start the engine and observe the engine idle speed.
The presence of dirt in the fuel system may affec
t
the fuel injection system.
