Thermatic® Electric Fan Switch Combo (12V & 24V) (Part #0400)

This value pack combines Part Numbers #0401 and #0409, providing a convenient and economical solution for controlling Thermatic® Fans and Electric Water Pumps (EWP®). The mechanical switch senses coolant temperature as it exits the engine block and adjusts fan operation accordingly.

The switch is adjustable from 40°C to 100°C (104°F to 212°F) and installs directly into the top radiator hose using the included Inline Sensor Adaptor. The kit includes all necessary components for a watertight, effective installation.

Note: For EWP control, use Digital Controller Part #8002 for variable speed management.
