Section V Engine Cooling System
Warning:
Do not open the cover of radiator or loose the bolt for drainage when the engine runs or the
radiator is too hot, to avoid serious hurt caused by the boiling coolant and steam. Besides, the
engine and cooling system may also be damaged. Stop the engine and wait till it is cool.
Otherwise, extra care should be taken when you open the cover. Place a thick cloth on the cover,
and rotate it counterclockwise slowly and repeat this operation until the pressure is discharged.
When you ensure there is no pressure, press down the radiator cover by the cloth and then open
it.
