Kawasaki VERSYS (2006) [202/627] Thermostat valve opening temperature

4-18 COOLING SYSTEM

Thermostat

•

Align the line [A] of the thermostat housing and the red

mark [B] of the radiator hose [C].

•

Install the radiator hose clamp [D] as shown.

•

Tighten:

Torque - Radiator Hose Clamp Screws: 2.0 N·m (0.20 kgf·m,

18 in·lb)

•

Fill the radiator with coolant (see Coolant Change in the

Periodic Maintenance chapter).

Thermostat Inspection

•

Remove the thermostat (see Thermostat Removal), and

inspect the thermostat valve [A] at room temperature.

If the valve is open, replace the thermostat with a new

one.

•

To check valve opening temperature, suspend the ther-

mostat [A] in a container of water and raise the tempera-

ture of the water.

○

The thermostat must be completely submerged and must

not touch the container sides or bottom. Suspend an ac-

curate thermometer [B] in the water so that the heat sen-

sitive portions [C] are located in almost the same depth.

It must not touch the container, either.

If the measurement is out of the specified range, replace

the thermostat with a new one.
