ENGINE COOLING 6B – 5
ENGINE COOLANT CHANGE
PROCEDURE
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 radiator cap, put a piece
of thick cloth on the cap and loosen the cap slowly
to reduce the pressure once 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 results it is suggested that the engine
cooling system be flushed at least once a year. It is
advisable to flush 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 minor cracks.
Isuzu recommends using Isuzu genuine anti-freeze
(ethylene-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 off coolant may sometimes
cause the coolant to overflow from the filler neck
even before the engine and radiator are completely
full.
If the engine runs under this condition, shortage of
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 than 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 over
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 full, pull out the filling hose
and check to see if air trapped in the system is
dislodged and the coolant level goes down. Should
the coolant level go down, repeat topping-off until
there is no more drop in the coolant level.
6. Directly after filling the radiator, fill the reservoir to
the maximum level.
7. Install and tighten radiator cap and start the engine.
After idling for 2 to 3 minutes, stop the engine and
reopen radiator cap. If the water level is lower,
replenish.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 radiator cap, put a piece
of thick cloth on the cap and loosen the cap slowly
to reduce the pressure once the coolant has
become cooler.
8. After tightening radiator cap, warm up the engine at
about 2,000 rpm.
Set heater adjustment to the highest temperature
position, and let the coolant circulate also into
heater water system.
9. Check to see the thermostat has opened by the
needle position of a water thermometer, conduct a
5-minute idle again and stop the engine.
10. When the engine has been cooled, check filler neck
for water level and replenish if required. Should
extreme shortage of coolant be found, check the
coolant system and reservoir tank hose for leakage.
11. Fill the coolant into the reservoir tank up to “MAX”
line.

THERMOSTAT
REMOVAL
1. Disconnect battery ground cable.
2. Drain coolant from the radiator and engine.
3. Thermostat housing
1) Remove mounting bolt and remove thermostat
housing together with radiator hose.
4. Gasket
5. Thermostat
INSPECTION
Make necessary repair and parts replacement if
excessive wear or damage is found during inspection.
Submerge the thermostat assembly in the water.
Place wooden blocks on the bottom of the water
container.
Do not heat the thermostat directly.
Gradually increase the water temperature. Stir the
water so that the entire water is the same temperature.
1) Make sure that valve begins to open at the
specified temperature.
Valve Opening Temperature: 85°C (185°F)
2) Make sure that valve opens fully at the specified
temperature.
Valve Full Open Temperature: 100°C (212°F)

(1) Priming Pump
(2) Fuel Filter Cartridge
A cartridge type fuel filter is used along with the piston
type fuel pump on the high pressure oil pump.
The fuel filter removes foreign material from the fuel
before it reaches the fuel pump.
A diaphragm type priming pump is installed at the top of
the fuel filter. It is used during the air bleeding
procedures.

1. Construction of Fuel Injector
The fuel injector is comprised of the solenoid
section, hydraulic line, and fuel line. Fuel injection is
controlled by the continuity time signal and
continuity start timing signal sent by the ECM
(Electronic Control Module) to the solenoid.
2. Working of Fuel Injector
1) The ECM detects the working of the engine from
its input signals, such as engine speed
accelerator throttle opening, and engine coolant
temperature, sending the optimal signals to the
solenoid.

QOS4 PREHEATING SYSTEM
GENERAL DESCRIPTION
QOS4 preheating system features a quick-on glow plug
with thermometer control of the glowing time and the
afterglow time function.
The system consists of the ECM, indicator lamp, ECT
sensor, vehicle speed sensor, relay and temperature
self-control type glow plugs.With the employment of the ECT sensor, the glow time
changes according to the engine coolant temperature,
thus allowing optimum starting conditions to be
obtained.
The after glow time function is controlled by ECM.
NOTE:
Refer to DTC P0380 and P0381 of 6E section.
