Draining and flushing the Cooling system

NOTE: Drain and flush the radiator and
engine block every 12 months. Refill with a
50/50 mixture of permanent antifreeze and
clear water.
To drain the cooling system:
1. Use a suitable receptacle to catch the used
coolant. Remove the radiator cap and open
the drain valve, A, on the left-hand more
frame to drain the radiator and engine block.
2. After the coolant has drained, place a water
hose in the radiator filler neck and run water
through the system. When water is flowing
from the block drain valve, start the engine.
When the water flowing from the drain valve,
is free of discoloration and sediment, stop the
engine and remove the hose. Allow all water
to drain from the system through the drain
valves.
3. Close the drain valve and slowly refill the
system with a 50/50 solution of permanent
antifreeze and clear water. Fill until the
coolant level is approximately 3.8 cm-5 cm
below the bottom of the filler neck. Do not fill
beyond this level.
4. Clean the radiator cap and cap seal and
install the cap.
5. Fill the coolant recovery reservoir bringing the
fluid level up until it is between the full and
low marks on the reservoir.
6. Pull down the seat frontward, tilt the front
screen C frontward and remove chaff, dust,
or other foreign substances. The foreign
substances can be dropped onto the ground
through the rubber at the lower part.
7. Pull out the radiator screen B sideways and
clean it.
8. Run the engine until normal operating
temperature is reached, then stop the engine.
Recheck the coolant level when the engine is
cold and add additional coolant as
necessary.
