ENGINE COOLING SYSTEM
Engine cooling system provides the engine heat to remain in appropriate temperature
interval, thus the engine works efficiently and by maintaining the oil viscosity the wear
of the engine parts is prevented. The system also cools the transmission. At the same
time, it also ensures the hot water necessity of the heating system and the heating of
diesel exhaust emission fluid tank (optional) in very low temperatures. The cooling fluid
used in cooling system is a mixture of 50% water and 50% antifreeze, the antifreeze
that shall be used have to be suitable for ASTM D6210 standard. This mixture has the
freezing point of - 36 °C and boiling point of +108 °C. No additives should be used in
cooling fluid.
ENGINE COOLING, CABIN HEATER and A/C SYSTEMS LINE FILLING AND
AIR RELIEF
1.
Position the vehicle on a flat ground.
2.
When there is a situation in which it is not necessary to run the cabin heater and
A/C system, service maintenance is required, and the vehicle must be transferred
to a place to start immediately, processes stated in the 12
th
and following articles
must be applied.
3.
Open the manual valves and air relief valves on the waterlines tied to cabin heater
and A/C units (in the engine water Inlet and outlet).
4.
Open the top and side caps of expansion tank.
5.
Starts filling the engine cooling system fluid with the mixture of 50% antifreeze and
50% diluted water from the cap on the side surface of expansion tank.
6.
When the expansion tank is full, stop filling. Wait for 1-2 minutes before starting the
engine to make sure that air which entered in the system from natural ways is
discharged and cooling fluid level is balanced. Then add water to the tank again.
7.
Start the engine and open the entire heating system in the maximum position. Take
the controller to manual maximum heating mode, quickly press the degree
increasing key on the control panel to take to shocking mode and make sure that
electronic three way cock is open. System pump and heated A/C pump will be
operating thus and there will be an “operating” signal on the A/C controller screen.
8.
As the vehicle runs, keep adding engine cooling system fluid up to the maximum
level of the expansion tank.
9.
After starting a cool engine, gradually increase the engine speed to make sure
that sufficient amount of oil goes to engine bearings and oil pressure is balanced.
10.
For air relief, start the engine in raised idling speed and release the air from air
release valves on the cabin heaters (System's air must also be relieved from the air
relief valves on the heated cabin heater).
