Inspection
The reserve tank is under footboard left.
Check the coolant level through the
inspection window (1) at the front lower
cover while the engine is at the normal
operating temperature with the scooter in an
upright position. If the coolant level is below
the LOWER level mark (3), remove screw (4)
and reserve tank lid (5) and reserve tank cap
(6) and add coolant mixture until it reaches
the upper level mark (2).
Always add coolant to the reserve tank. Do
not attempt to add coolant by removing the
radiator cap.
If the reserve tank is empty, or if coolant loss
is excessive, check for leaks and see your
KYMCO dealer for repair.
Coolant recommendation
The owner must properly maintain the
coolant to prevent freezing, overheating, and
corrosion, use only high quality ethylene
glycol antifreeze containing corrosion
protection inhibitors specifically
recommended for use in aluminum
engines.(See antifreeze container label.)
Use only low-mineral drinking water or
distilled water as a part of the antifreeze
solution. Water that is high in mineral content
or salt may be harmful to the aluminum
engine.
Using coolant with silicate inhibitors may
cause premature wear of water pump seals or
blockage of radiator passages.
Using tap water may cause engine damage.
The factory provides a 50:50 solution of
antifreeze and distilled water in this scooter.
This coolant solution is recommended for
most operating temperatures and provides
good corrosion protection.
A higher concentration of antifreeze
decreases the cooling system performance
and is recommended only when additional
protection against freezing is needed. A
concentration of less than 40:60 (40%
antifreeze) will not provide proper corrosion
protection. During freezing temperatures,
check the cooling system frequently and add
higher concentrations of antifreeze (up to a
maximum of 60% antifreeze) if required.
