Removal
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.
1.
Remove the seat (see page
17-17
for Rocket III and
Classic, see page
17-18
for Rocket III Touring).
2.
Disconnect the battery, negative (black) lead first.
3.
Drain the coolant (see page 12-6>.
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.
4.
Disconnect the top and bypass hoses at the
thermostat housing.

Inspection
1.
Inspect the thermostat at room temperature. If the
valve is open, the thermostat must be replaced.
2.
To check the valve opening temperature, suspend
the thermostat in a container of water together with
a thermometer. Raise the temperature of the water
until the thermostat opens. The thermostat should
start to open at 88°C
+/-
5°C.
3.
If the temperature at which thermostat opening
takes place is incorrect, replace the thermostat.
