So I recently got this 1986 Corvette and I wanna do a cooling upgrade cause I heard that’s a recommended upgrade, I just wanted to ask someone who knows a lil more than me, which fan switch should I get and how do I upgrade it

… also my radiator fan seems like it’s not working at the moment (only test I know is to turn the a/c on and see if the fan goes with it and so far I don’t hear it or see it spinning ) is there a way I can test the components before I fully commit or should I just start replacing stuff
