Universal 3/8" NPT Radiator Fan Temperature Sensor Switch (180°F On)

Got an electric fan that needs a brain?

This universal thermo switch from Carpopart is the ticket.

It screws into a standard 3/8\ NPT port in your radiator or intake manifold.

When the coolant hits 180 degrees Fahrenheit, it closes the circuit and turns your fan on, keeping your engine cool.

It's a simple, mechanical switch made of metal with a copper-tone shell.

You get one switch in the package.

Just wire it up to a relay, and you've got an automatic cooling setup.

It's a universal part, so it'll work for a ton of projects, from hot rods to off-road rigs.

Just a heads-up on the Prop 65 warning for our California friends.
