12. Coolant Check
QQ6 engine has a main radiator and an auxiliary radiator.
Check whether the auxiliary radiator’s coolant level is between the MAX and MIN marks. If below
the MIN mark, please refill the coolant.
CAUTION: Please DO NOT refill the coolant when the engine is in hot state. Please refill the
coolant after the engine cools down.
When refilling the coolant, pay attention to the following methods:
Method to refill the coolant at the filler cap: In case of the engine’s cold state and standstill, turn
the filler cap in the clockwise direction and apply the pressure on the cap to open it, and then refill
the coolant until it can be seen viewing from the filler opening. Tighten the filler cap in the
anticlockwise direction, start up the engine and let it operate at the idle speed for about 1 minute,
and then shut down the engine. Open the filler cap and continuously refill the coolant until it can be
visiable viewing from the filler opening.In case that the engine’s water temperature is high or in
case of each maintenance, note that the coolant is refilled in time from the filler cap.
Method to refill the coolant into an auxiliary radiator: In case of the engine’s cold state and
standstill, pull upwards and open the auxiliary radiator filler cap. The capacity of coolant refilled
must exceed the MIN mark and below the MAN mark. Regularly observe the capacity of coolant in
the auxiliary radiator. Refill the coolant in time if below the MIN mark. The coolant level can be
checked through the semi-transparent auxiliary radiator. When the engine is in the cold state, the
coolant level shall be between the MIN and MAX marks.
If it is necessary to refill the coolant when the engine is hot, wait for 10 minutes first to cool the
engine. Loosen the filler cap one quarter turn to release the pressure. Wait for a period of time, and
then fully open the cap to refill the coolant which conforms to the specifications of this vehicle.
Using the coolant with the proper concentration can’t only protect the engine free from be frozen in
