COOLING SYSTEM
COOLANT LEVEL INSPECTION
Place the machine on the level ground.
Remove the front center cover (refer to the
"FRAME COVERS" section in the chapter
2).
Check the coolant level in the coolant
reservoir when the engine is cold as the
coolant level will vary with engine
temperature. The level should be between
the "FULL" (2) and "LOW" (3) level
surface.
If the level is low, remove the reserve tank
cap (1) and fill the tank to the "FULL"
level line with 1:1 mixture of distilled water
and antifreeze (coolant mixture preparation:
refer to the chapter 6 "COOLING
SYSTEM")
Using coolant with silicate inhibitors
may cause premature wear of water
pump seals or blockage of radiator
passages. Using tap water may cause
engine damage.
Check to see if there are any coolant leaks
when the coolant level decrease very
rapidly.
If reserve tank becomes completely empty,
there is a possibility of air getting into the
cooling system.
Be sure to remove all air from the cooling
system (refer to the "COOLANT
REPLACEMENT" section in the chapter
6).
Reinstall the filler cap.
