6.9.3 CHECKING THE THERMAL SWITCH
OPERATION
Thermal switch
switch on
switch off
NOTE
The thermal switch switches to on at a tempera-
ture of ~ 100°C (212°F) and to off at ~ 85°C (185°F); with-
in this range of values, it may switch to on or off indiffer-
ently.
Remove the thermal switch (1), see 5.4 (REMOVING
THE COOLANT THERMAL SWITCH).
Connect a tester (2) (set as an ohmmeter) to the ther-
mal switch (1) as illustrated in the diagram.
Immerse the thermal switch (1) in a container (3) hold-
ing coolant.
Immerse a thermometer (4) with a 0 – 150 °C (32 – 302
°F) range in the same container.
Place the container on a burner (5) and slowly warm up
the coolant.
Check that the temperature reading on the thermome-
ter (4) and the value indicated by the tester (2) corre-
spond to the data in the table.
Coolant temperature
(°C) (°F)
> 100 > 212
< 85 < 185
If the values depart excessively from those indicated
in the table, change the thermal switch (1).
