Drainage
Do not remove the coolant pressure cap when the
engine is hot. When the engine is hot, the coolant inside
the radiator is hot and also under pressure. Contact with
hot coolant will cause scalds and skin damage.
Before starting work, ensure the motorcycle is stabilised
and adequately supported. This will help prevent it from
falling and causing injury to the operator or damage to
the motorcycle.

10-85>.
2. Remove the coolant pressure cap on the upper
