I'm pulling together all the parts I need for my motor swap (the ford 302). I bought a larger radiator (27.5"x19"), and I plan on picking up a Taurus fan from the local pick n pull. So what's the correct way to wire this up? What components do I need to make it run? The car will have a/c, and a trans cooler if it matters.



I've seen the universal e-fan controllers at summit, but wasn't sure what I really need or don't need.



I know this isn't exactly 2nd gen related (though it is going in a vert), but anyone could use this info for any car, and you guys are some pretty fart smellers.

99% of e-fans just have two wires, 12v and ground. Depending on which you put 12v to changes the direction the fan spins. Just get a switch at Radioshack, run a ground from it to somewhere inside the car, then a ground from the switch to the fan, and 12v from the battery to the fan. The switch will complete the circuit when you flip it on and the fan will kick on. Just flip her on when you're sitting still for a while.

i dont think ive seen any pics of sum1 putting one on the front and one of the back of the rad. is that feasible?

Baldy

Ummm no, I would not consider that the "correct" method. I would also not accept "just wire it to a 12v source and have it be on all the time".



I need some sort of temperature control thingy, kicks on and off at certain temperatures.

moltar

Well, isn't the stock fan controlled by a mechanically temperature activated type setup inside the fan clutch? It just kicks on and off depending on the viscosity of the liquid from what I understand. If you're wanting to run it based on teh water temp readings, I have no idea how you would go about that. I'd assume you need some sort of relay and what not. Sorry.

Edit: You're doing a V8 swap, I totally missed that part. So 99% of my advice is worthless.

It's simple enough, the fan will have 2 wires, you'll need a thermoswitch connected to it to control it via a relay, they're usually screwed in somewhere on the rad - for my car's rad it wasn't so I got a copper t-junction and fitted the thermoswitch into a blanking piece and fitted the whole lot in before the rad. hope that makes sense.

teknics

yea just look for a temperature switch, you wire it betwen the 12v source and the fan and jam a piece of the switch through the rad fins, when they get to the temp you set it at it sends power to the fan.



you dont need a whole big controller, but that does the same thing too.

So, where would one go about looking for this thermoswitch? I also have an E-Fan that is sitting in limbo with life and another means of being hooked up. Would prefer not having to switch it on and off between red lights ya know?
