Honda CBR 250R Manual page 29

Use any genuine HONDA PRE-MIX COOLANT
without diluting with water.
NOTICE
Do not use non-ethylene glycol coolant,
tap water, nor mineral water when adding
or replacing the coolant.
Use of improper coolant may cause damage,
such as corrosions in the engine, blockage
of the cooling passage or radiator and
premature wear of the water pump seal.
Inspection
The reserve tank is located under the right
side of the crankcase.
Check the coolant level in the "Reserve
Tank" (1) while the engine is at the normal
operating temperature with the vehicle in
an upright position. If the coolant level is
below the "Lower Level Mark" (2), remove
the "Screw" (3). Pull out the "Prong" (4) from
the "Hole" (5). Remove the "Cover" (6) and
"Reserve Tank Cap" (7). Add coolant mixture
until it reaches the "Upper Level Mark" (8).
Always add coolant to the reserve tank.
Honda Motorcycle & Scooter India Pvt. Ltd.
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 visit
your nearest Honda dealer for repair.
