WARNING: Do not remove expansion tank cap (2)
until the coolant temperature in the radiator is cool.
Hot steam may spout out, possibly causing severe
burns. After the coolant temperature cools, slowly
loosen expansion tank cap (2) to release the inside air
pressure before removing expansion tank cap (2).
Check the coolant level at expansion tank (1).
Sight gauge (3) of expansion tank (1) should be filled with
coolant at normal level.
If not, add the coolant mixture via cap hole (2) on the
expansion tank (1).

NOTE: Do not fill up expansion tank (1).
 When refilling a long life coolant (LLC), use the same
brand product and the same mixture ratio as already
used in the machine.
 If only water is refilled, the mixture ratio in the long life
coolant (LLC) is diluted so that anti-rust and antifreeze
effect in the coolant will become deteriorated.
