MAINTENANCE AND ADJUSTMENT
j
•
If whitish cotton-like wafts are observed, aluminum
parts in the cooling system are corroded and the
system must be flushed.
•
If the coolant is brown, iron or steel parts are rust-
ing and the system must be flushed.
•
Check the cooling system for damage, loose con-
nections, and leaks.
•
Install the coolant drain bolt with its new gasket
at the water pump cover and apply the specified
torque.
NOTE
°
Always replace a gasket with a new one.
Tightening Torque
Coolant Drain Bolt:
7.0 N·m (0.71 kgf·m, 62 in·lb)
•
Fill the radiator up to the bottom of the radiator filler
neck with coolant.
•
Lean the motorcycle slightly until the radiator filler
neck is level to the ground so that the filler neck
is located uppermost in order to exhaust the air
accumulated in the radiator.
NOTICE
Use coolant containing corrosion inhibitors
made specifically for aluminum engines and
radiators in accordance with the instruction
of the manufacture.
Soft or distilled water
must be used with the antifreeze in the cool-
ing system. If hard water is used in the sys-
tem, it causes scale accumulation in the wa-
ter passages, and considerably reduces the
efficiency of the cooling system.
NOTE
°
Pour in the coolant slowly so that it can expel the
air from the engine and radiator.
•
Install the radiator cap.
•
Check the cooling system for leaks.
•
Start the engine and warm up thoroughly, then
stop it.
•
Check the coolant level after the engine has
cooled down. The coolant should come up to the
bottom of the radiator filler neck.
•
If the coolant level is low, add coolant up to the
bottom of the radiator filler neck.
•
Install the radiator cap.
•
Check the cooling system for leaks.
