Hey everyone I wanna wire my fans to come by themselves when they reach a certain temp an turn off when the motor cools down I'm not using any computer or any sensors I just have a 3 pod guage cluster (water,oil,volt) I have to keep my fans constantly on when driving in the city. When I'm on the highway the car stays right around 180 which is perfect mostly need help in driving in the city with cooling (1989 Gta trans am 5.7 355 sbc 700r4 auto trans, champion 3 core all aluminum radiator)

 

Lots of good fan controllers that control the fan or fans through probes in the Radiator or stock fan switch location that will work for you. Check Summit Racing or do a search on here for fan controllers. Lots of options out there
Actually there's more info on this topic on the cooling board , check there first
Here's one example of a deluxe one

This is a very sweet way of doing I just don't understand on how to do the wiring part looks like I'll be saving up to get this setup thanks for ur help

 

comes with great directions and it turns out to be pretty easy. Have fun!

 

This is what I am using. I have a dual fan set up with the champion radiator. I use the stock fan switch to kick the first an on and the painless switch which is screwed into my intake manifold to activate the second fan.
