Fan-Thom II Electric Fan Relay with Thermostatic Switch
195°F On/185°F Off (thread size: 3/8"-18NPT)

This Fan-Thom II kit comes with a threaded thermostat that screws into the engine block or intake manifold for a professional looking installation. This is inexpensive protection for an electric fan and a vehicle's wire harness. Provides constant voltage, protects from voltage and amperage spikes and prevents the fan from back feeding voltage through the vehicle's wire harness.

Kit includes:

• SPST 40 Amp relay
• 30 Amp circuit breaker
• Thermostatic switch
• 1/2"NPT to 3/8"NPT adapter
• Relay base with harness
• Crimp-on terminals
• Mounting hardware
