coolant temperature and oil pressure during the
running-in period, which must be within the
specified range.
- During the running-in operation of new vehicles,
the fuel consumption of the engine is higher and the
oil level should be checked daily.
Perform the following items after the running-in
- Change the engine oil.
- Change the oil filter.
- Drain the diesel strainer filter, check and tighten
the fuel tank strap.
- Change the transmission oil, check and tighten
fixing bolts of transmission shaft.
- Change the drive axle oil.
- Change the power steering fluid and check the
steering gear fixing bolt.
- Check the fixing bolt of steering gear bracket.
- Check the connecting bolt between steering shaft
and steering gear.
- Check the fixing nut of steering arm.
- Check and tighten the wheel nuts.
- Check and tighten the leaf spring U-bolt.
- Check brake clearance and friction plate wear.
- Check and tighten the front and rear suspension
cushion retaining bolts of the cab.
Caution
⊙It is recommended that the fluid change should
be made in FAW service stations.
⊙Ensure to use the grease and oil recommended
by this instruction.
- When replacing the parts, use those bearing FAW
identifications, which can be purchased from the
special stores designated by FAW or FAW service
stations.

Correct operation
Information to the driver
Speedometer
Indicate the speed of the vehicle.
－The driving mileage is displayed on the LCD
screen.
Engine tachometer
The engine tachometer is better to control the
engine speed in the green zone ①, where the best
comprehensive performance of the engine can be
obtained.
The engine speed exceeds the red range ②,
which means that the engine speed exceeds the limit.
Long-time over-speed operation can cause damage
to the engine.
Fuel gauge
Indicates the amount of fuel in the fuel tank.
0: Indicates that the fuel tank is empty.
1: Indicates the fuel tank is full.
Caution
When the pointer is close to the red range, the fuel
shall be supplemented in time. Otherwise, the oil
supply system will allow the air to enter and an
exhaust is required again when starting again.

Jiefang J6 China IV, China V series instruction
Correct operation
Water thermometer
The water thermometer indicates the coolant
temperature of the engine.
After each cold start of the engine, the preheating
shall be carried out at low speed. When the
temperature of the coolant reaches more than 50°C,
start driving.
During driving, the normal temperature range of
the coolant is (75 ~ 95) ℃.
If the pointer exceeds 105°C, the warning lamp
will be on, indicating that the engine is overheated
at this time, and the vehicle shall be parked at a safe
place and run at a speed slightly higher than idle
speed in order to cool the engine.
After the pointer returns to the normal operating
position, stop the engine for the following checks:
- Check the radiator and the hoses for leaks.
- Check the amount of coolant and add if the
coolant is insufficient.
- Check whether there are sundries on the front of
the radiator.
Caution
Do not stop the engine immediately after stopping,
otherwise the engine cylinder block temperature
will rise sharply and cause the engine to be sintered.
LCD screen (J6P)
A LCD screen includes a main LCD screen and a
secondary LCD screen.
- The upper part is the main LCD screen.
- The lower part is a secondary LCD screen.

- Lower part 1: Status bar shows the brake air
pressure, and the circuit with relatively small air
pressure, between the front brake circuit and the
rear brake circuit.
Caution
⊙The brake pressure should be maintained in the
range of (0.7-0.9) MPa during driving.
⊙Stop the vehicle immediately and check if it is
less than 0.55MPa (i.e. the brake system fault alarm
lamp is on).
⊙The barometer displays the fault, please check
whether the air pressure sensor needs to be
replaced.
- Lower part 2: The state bar (or numerical value)
indicates the working pressure of the lubricant in
the engine and main oil duct.
It is required to observe the oil pressure during
driving. When the engine is running normally, the
oil pressure indication range is (0. 25-6.0) MPa.
If the pressure gauge pointer is less than 0.7, the
engine should be shut down immediately to find out
the cause of the fault.
