4-8 COOLING SYSTEM
Coolant
Coolant Deterioration Inspection
•
Visually inspect the coolant in the reserve tank [A].
If whitish cotton-like wafts are observed, aluminum parts
in the cooling system are corroded. If the coolant is
brown, iron or steel parts are rusting. In either case, flush
the cooling system.
If the coolant gives off an abnormal smell, check for a
cooling system leak. It may be caused by exhaust gas
leaking into the cooling system.
Coolant Level Inspection
•
Refer to the Coolant Level Inspection in the Periodic Main-
tenance chapter.
Coolant Draining
•
Refer to the Coolant Change in the Periodic Maintenance
chapter.
Coolant Filling
•
Refer to the Coolant Change in the Periodic Maintenance
chapter.
Pressure Testing
•
Remove the right middle fairing (see Middle Fairing Re-
moval in the Frame chapter).
•
Remove the radiator cap, and install a cooling system
pressure tester [A] on the filler neck.
NOTE
â—‹
Wet the cap sealing surfaces with water or coolant to
prevent pressure leaks.
•
Build up pressure in the system carefully until the pres-
sure reaches 123 kPa (1.25 kgf/cm², 18 psi).
NOTICE
During pressure testing, do not exceed the pres-
sure for which the system is designed. The maxi-
mum pressure is 123 kPa (1.25 kgf/cm², 18 psi).
•
Watch the gauge for at least 6 seconds.
If the pressure holds steady, the system is all right.
If the pressure drops and no external source is found,
check for internal leaks. Droplets in the engine oil indicate
internal leakage. Check the cylinder head gasket and the
water pump.
•
Remove the pressure tester, replenish the coolant, and
install the radiator cap.
•
Install the right middle fairing (see Middle Fairing Installa-
tion in the Frame chapter).
