the liquid level in the radiator, if the
liquid is found insufficient, it should
be added to specified level.
3. Drainage of cooling system. In
cold region and in winter, for long -
time parking or finishing using the
vehicle everyday without using anti-
freezing preservative liquid, the cool
鄄
ing system must be drained and the
water filler cap of the radiator must
be opened to avoid the incomplete
drainage of cooling water.
4. After engine operating for a long
time , furring can be produced in the
cooling water and it should be
cleaned in time .Clean it with the fol
鄄
lowing method: mix 700 -800gram
kerosene, add the mixture liquid into
the cooling water , run in medium
speed for 5 -10 minutes, then after
engine stop working for 10-12 hours,
restart the engine and run for 10-15
minutes. Then drain the cooling sys
鄄
tem with cleaned water.
Items in using long-term effective an 鄄
ti-freezing preservative liquid
1. Choose suitable antifreeze accord 鄄
ing to the lowest temperature of the
region, if the lowest temperature of
the region is -25
益 , antifreeze of
which solidifying point is -30 益
should be chosen.
2. Anti-freezing preservative liquid of
the same type should be used in
adding in case of deposition.
3. If finding deterioration of the anti-
freezing preservative liquid, replace
it entirely at once. Normal color of the
anti-freezing liquid is green or blue,
if the liquid is deteriorated, the color
will become deep red because of in
鄄
filtration of impurity.
Adjusting of tension degree of fan belt
pulley
1. Too tight or too loose fan belt does
no good to operate the engine .
Consult engine assembly for details
of adjusting methods.
2. Adjusting methods: Adjust the fan
belt with adjusting bolts first, then do
accurate adjusting with the tension
rod; adjust degree of tension of the
V -belt with fingers, press each belt
with 98N force. Length of crankshaft
belt pulley-belt tension pulley is 10-
15 mm and length of belt tension pul
鄄
ley-fan belt pulley is 7-8mm.

Brief description of the structure:
Accelerating transmission device is
composed of accelerator pedal
mechanism
尧 accelerator drawing wire
and speed governor handle of the en 鄄
gine. (As shown in the figure above)
When pressing the pedal, driving
device of the mechanism pulls the
drawing wire and controls the open 鄄
ing extent of the accelerator to in 鄄
crease or decrease the speed
1. Accelerator pedal mechanism:
This mechanism adopts the latest
structure of ISUZU truck. It operates
simply and safely and is connected
to the accelerating drawing wire and
the hand throttle drawing wire; struc 鄄
ture of the pedal adopts injected
molding type, which makes the as
鄄
sembly convenient and causes little
operating noise.
2. Accelerating wire drawing:
It is operated with soft drawing wire
and has a safe structure; it's char
鄄
acterized with convenient layout 尧 lit 鄄
tle frictional resistance and stable
transmission.
