COOLING SYSTEM
RADIATOR CAP/SYSTEM PRESSURE
INSPECTION
Remove the radiator cap (page 8-5).
Wet the sealing surfaces of the cap, then install the cap
onto the tester [1].
Pressure test the radiator cap.
Replace the radiator cap if it does not hold pressure, or
if relief pressure is too high or too low.
It must hold specified pressure for at least 6 seconds.
RADIATOR CAP RELIEF PRESSURE:
108 – 137 kPa (1.1 – 1.4 kgf/cm
Install the tester to the radiator.
Pressure the radiator, engine and hoses, and check for
leaks.
Excessive pressure can damage the cooling system
components. Do not exceed 137 kPa (1.4 kgf/cm
psi).
Repair or replace components if the system will not hold
specified pressure for at least 6 seconds.

COOLANT REPLACEMENT

PREPARATION
• The effectiveness of coolant [1] decreases with the
accumulation of rust or if there is a change in the
mixing proportion during usage. Therefore, for best
performance change the coolant regularly as
specified in the maintenance schedule.
• Mix only distilled, low mineral water [2] with the
antifreeze [3].
RECOMMENDED ANTIFREEZE:
High quality ethylene glycol antifreeze containing
silicate-free corrosion inhibitors
RECOMMENDED MIXTURE:
1:1 (mixture with distilled water)
REPLACEMENT/AIR BLEEDING
When filling the system or reserve tank with coolant or
checking the coolant level, place the motorcycle in an
upright position on a flat, level surface.
Remove the lower cowl (page 2-28).
Remove the screw [1] and radiator cap [2].
