Suzuki GSX-R 1000 Service Manual: Thermostat inspection
Inspect the thermostat in the following procedures:
- remove the thermostat. Refer to “thermostat removal and installation” .
- Inspect the thermostat pellet for signs of cracking.

- Test the thermostat at the bench for control action.
Caution
- do not contact the thermostat (1) and
column thermometer (2) with a pan.
- As the thermostat operating response to
water temperature change is gradual, do
not raise water temperature too quickly.
- The thermostat with its valve open even
slightly under normal temperature must be
replaced.
|
- Immerse the thermostat (1) in the water contained in
a beaker and note that the immersed thermostat is in
suspension.
- Heat the water by placing the beaker on a stove and
observe the rising temperature on a thermometer
(2)

- Read the thermometer just when opening the
thermostat. If this reading, which is the temperature
level at which the thermostat valve begins to open, is
out of the standard value, replace the thermostat
with a new one.
Thermostat valve opening temperature
standard: approx. 82 °C (180 °f)
- Keep on heating the water to raise its temperature.
- Just when the water temperature reaches specified
value, the thermostat valve should have been lifted
by at least 8 mm (0.31 In). A thermostat failing to
satisfy either of the two requirements (start-to-open
temperature and valve lift) must be replaced.
Thermostat valve lift “a”
standard: over 8 mm (0.31 In) and at 95 °c (203
°f)

- Install the thermostat. Refer to “thermostat removal and installation” .

Ecm / various sensors
Since each component is a high-precision part, great
care should be taken not to apply any severe impacts
during removal and installation.
Be careful not to touch the electrical terminals of the
electronic parts (ecm, etc.). The static electricity from
your body may damage them. ...
Radiator reservoir tank inspection
Inspect the radiator reservoir tank in the following
procedures:
remove the right side cowling. Refer to “exterior parts removal and
installation” in section 9d .
Inspect the radiator reservoir tank (1) for leaks. If any
defects are found, replace the radiator reservoir tank
