Open the right side cover.
Figure PM-25
Check the coolant level in the coolant recovery tank
(Item 1) [Figure PM-25].
The coolant level must be between the MIN and MAX
marks on the coolant recovery tank when the engine is
cold.
NOTE: The cooling system is factory filled with
propylene glycol (purple colour). DO NOT mix
propylene glycol with ethylene glycol.
IMPORTANT
AVOID ENGINE DAMAGE
Always use the correct ratio of water to antifreeze.
Too much antifreeze reduces cooling system
efficiency and may cause serious premature engine
damage.
Too little antifreeze reduces the additives which
protect the internal engine components; reduces the
boiling point and freeze protection of the system.
Always add a premixed solution. Adding full strength
concentrated coolant can cause serious premature
engine damage.

IMPORTANT
Wear safety glasses to prevent eye injury when any of
the following conditions exist:
• When fluids are under pressure.
• Flying debris or loose material is present.
• Engine is running.
• Tools are being used.
