ELECTRIC COOLING FAN THERMOCONTACT

Check the setting of the thermocontact by operating as follows:

• Remove the thermocontact from the radiator.
• Hang the thermocontact in a container full of water and heat the water.
• Using a thermometer and a multimeter, check that the contact closes on the two pins (of connector A) at the 2nd speed cut-in temperature.
• In the same way check that the thermocontact closes between the pins of connector A and B at the 2nd speed cut-in temperature.

CAUTION
Neither the thermometer or the thermocontact must touch the bottom of the container.

If the correct values are not detected, replace the thermocontact.
