Inspection
The reserve tank is located underneath, on
the left hand side of the footrest.
Check the level of coolant in the reserve tank
(1) when the engine is at normal operating
temperature and the scooter is in a vertical
position.
If the coolant level is under the Lower level
mark (2) proceed as follows:
1. Remove the footrest cover (page 34)
2. Pull out the coolant tank compartment
cover (page 34)
3. Remove the reserve tank cap (page 34)
and add coolant mix until the "UPPER"
level mark (3) is reached.
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 Honda dealer for repair.
• Be sure to turn the ignition switch OFF
before adding the coolant.
