COOLING SYSTEM
SYSTEM TESTING
RADIATOR CAP/SYSTEM PRESSURE
INSPECTION
Remove the right middle cowl (page 2-6).
Remove the radiator cap [1].
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.
Apply pressure to 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
20 psi).
Repair or replace components if the system will not hold
specified pressure for at least 6 seconds.
COOLANT REPLACEMENT
REPLACEMENT/AIR BLEEDING
• When filling the system or reserve tank with coolant
or checking the coolant level, place the motorcycle in
