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
|
- 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” .
