Replace the coolant filter
Replace the coolant filter every 500 hours or twice a year.
The coolant filter prevents corrosion of the parts in the
coolant system.
Detaching
1. Remove the radiator cap.
2. Turn the shut-off valve (1) fully clockwise to close it.
3. Remove the filter cartridge (2) with the filter wrench.
Attaching
1. Apply lubricant thinly to the gasket surface of a new
filter cartridge.
2. Screw the filter cartridge until the gasket is brought into
contact with the seal surface of the filter head (3).
Turn the filter cartridge further by 1/2 to 3/4 turn from
this condition.
3. Turn the shut-off valve counterclockwise until it stops
to open it.
4. Attach the radiator cap.
5. Start the engine and check if no coolant leaks.
Check the coolant level again when air is discharged
from the coolant system completely.
WARNING
Do not remove the radiator cap when the radiator water temperature is high.
Otherwise, hot steam may spout out and you are in danger of getting burnt.
Wait until the radiator water temperature lowers. Loosen the radiator cap gradually to
remove it.
CAUTION
Do not pour oil into the coolant filter. Oil may deteriorate the coolant additive.
If the coolant filter is tightened excessively with a tool, its threads may be deformed or
the filter head may be damaged.
Set the shut-off valve to the “Open” position to avoid damages to the engine.
