Radiator Coolant; Cooling System - Honda CBR125R Owner's Manual

Install the oil strainer screen with the thin edge fac-
ing in and flange side facing up as shown.
Install the right crankcase cover (page 10-8).

RADIATOR COOLANT

Check the coolant level of the reserve tank with the
engine running at normal operating temperature.
The level should be between the "UPPER" and
"LOWER" level lines with the motorcycle in an
upright position.
If necessary, add recommended coolant.
RECOMMENDED ANTIFREEZE (Except CM type):
High quality ethylene glycol antifreeze containing
silicate-free corrosion inhibitors
RECOMMENDED ANTIFREEZE (CM type only):
Pro Honda HP coolant or equivalent high quality
ethylene glycol antifreeze containing silicate-free
corrosion inhibitors
Remove the single seat (page 2-4).
Remove the reserve tank cap and add the coolant to
the "UPPER" level line with a 1:1 mixture of distilled
water and antifreeze (coolant preparation: page 6-6).
Reinstall the reserve tank cap.
Install the single seat (page 2-4).
Check to see if there are any coolant leaks when the
coolant level decreases very rapidly.
If the reserve tank becomes completely empty,
there is a possibility of air getting into the cooling
system.
Be sure to remove any air from the cooling system
(page 6-7).

COOLING SYSTEM

Remove the middle cowl (page 2-9).
Check the radiator air passages for clogging or dam-
age.
Straighten bent fins, and remove insects, mud or
other obstructions with compressed air or low
water pressure.
Replace the radiator if the air flow is restricted over
more than 20 % of the radiating surface.
