2. To drain the coolant, open the radiator drain valve
and remove the radiator drain plug and remove
radiator cap. See the figure. The radiator cap must
be removed to completely drain the coolant.
3. After all coolant is drained, close the drain valve
and install the drain plug.
4. Fill with clean water and cooling system cleaner.
5. Follow directions of the cleaner instruction.
6. After flushing, fill with clean water and antifreeze
until the coolant level is just below the fill port on the
radiator. Install the radiator cap securely.
7. Fill with coolant up to the [FULL] mark on the
recovery tank.
Set the direction of the recovery tank cap outlet at
left front (45°). Set the bottom tip of the hose
between front side of radiator hose and inner side
of the frame. (This will prevent the hose from pulling
down and open the recovery tank cap.)
8. Start and operate the engine for a few minutes.
9. Stop the engine and let cool.
