Coolant Level Check
– Check the level of coolant every day!
– The level of coolant must be between the marks FULL and LOW

body to empty the coolant.

radiator, start the engine and run it at the speed higher than low idle
speed. When the pointer of cooling water thermometer enters into the
green area, continue to run the engine for over ten minutes.
– Close the engine, open the drain cock, and flush the cooling system with
fresh water until the drained water becomes clean so as to remove the
dirt and deposits.

antifreeze agent into the radiator as per the specified mixing ratio. In
order to prevent the air bubble from mixing into the system, add in the
