air-conditioning system.
2. Switch on with counter-clockwise rotation the
water valve of the two heaters of the inlet and
outlet water pipe of the evaporator from the
engine to air conditioner system.
Warm water valve for controlling the water inlet of
the air-conditioning system, see right figure:
3. Open the pressure cap on the top of heat
radiator, and slowly fill the coolant, and the
filling rate should be maintained at 19L/min,
and to ensure a fill rate of over 90% of the
total volume at one time.
4. After the coolant level is stable, start the
engine with the pressure cover open, run 25
minutes in total at low, high and idle speed,
ensure coolant temperature reaches 82
℃
and above, to remove the air accumulated in
the cooling system when filling in at the first
time.
5. Inspect the coolant level of the heat radiator,
add coolant to the appropriate position (6%
expansion space need to be reserved).
Tighten the pressure cap of the heat radiator.
5.7.3 INSPECT COOLANT LEVEL REGULARLY
Heat radiator is located at the tail of the machine.
Water inlet of heat radiator, see right figure:
1. Slowly uncap the pressure cap at the upper section of the heat radiator, and gradually
release the pressure.
Under thermo-mechanical state, do not immediately open the heat radiator
pressure cap, to avoid the high-temperature coolant or steam damaging the skin,
gradually open or wait until the coolant temperature drops down to about 50
℃
and
then open it.
