Engine coolant
WARNING
Hot liquid under pressure!
Never remove the filler cap or the recovery tank cap while the engine is running or the coolant is hot.
Let the system cool. Turn the filler cap to the first notch and allow any pressure to escape, and then
remove the filler cap. Loosen the recovery tank cap slowly to allow any pressure to escape.
Failure to comply could result in death or serious injury.

Draining and flushing the cooling system
NOTE: Drain and flush the radiator and engine block ev-
ery 1000 hours of usage or 24 months, whichever comes
first. 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 (1)
on the left- side of radiator to drain the radiator and
drain plug
(2) on right side of engine block to drain
engine block.
2. After the coolant has drained, place a water hose in
the radiator filler neck and run water through the sys-
tem. When water is flowing from the block drain plug
port start the engine. When the water flowing from the
block port is free from coloration and sediment, stop the
engine and remove the hose. Allow all water to drain
from the system through the radiator drain valve and
block port.
3. Close the radiator drain valve and reinstall the block
drain plug. Slowly refill the system with a 50/50 solution
of ethylene glycol antifreeze and water. Fill until the
coolant level is approximately
4 cm ( 1.6 in ) 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. Add coolant to the coolant reservoir (3) until fluid level
is between the “LOW” and “HIGH” lines on the side of
the reservoir.
6. 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.
NOTICE: Never run the engine when the cooling system is
empty. Do not add cold water or cold antifreeze solution if
the engine is hot.
