Cooling fan wired with correct polarity on the wiring?

What temp is Fan turning on at? Can you adjust what temp fan kicks on at?

The aluminum radiator you get from backdraft can be purchased with the mounting brackets installed as the aftermarket ones will mount a little different. I think the backdraft one also has option for the aluminum fan plenum and such….

One should always use a thermostat to keep proper operating temperature.
