2 Check level of the coolant
The coolant level is automatically monitored.
If coolant level gets too low
，
the digital indicator
displays a driver information on the combination
instrument. In this case, park vehicle in a safe place as
traffic conditions permit, stop engine and visually
check the coolant level.
Check the coolant level only when the engine doesn’t
work and its temperature is below 50
℃
.
The anti-freezing rust-inhibiting engine coolant level
can be observed from the observe pipe.
The coolant level should be between the maximum
level (MAX.) and minimum (MIN.) level indicators in
the compensation tank.
If it is necessary to add coolant to the system:
a.
Place the heating system command in the position
of maximum heating potency.
b. Add the coolant to the system up until the
maximum level indication. Only use coolant
which is recommended.
c. The compensation tank cover should not be
opened when temperature of the coolant is still
high to avoid being scalded Place the lid on the
system and turn it to the limit.
d. Pressure valve of the compensation tank should be
opened when adding the coolant to eliminate air in
coolant pipeline of the diesel engine.
e. Run the engine for a short time at varied rotations.
f. Stop the engine and check the coolant level.
If necessary add more coolant to the system
Anti-freeze and antirust solution (mixture of glycol and water) should be added to cooling system from
time to time to avoid sediment, frost, oxidation and increase boiling point.
Note: When adding coolant, please choose the same model to avoid sediment. If coolant is degenerative,
replace it immediately.
Coolant specification as shown below: users should choose products produced by normal factories
according to requirement
