hey do any of you know a page that has pics/writeups on how to hook a electric fan up. particularly the feiro fan because i have posed before but people just act like im an idiot for not knowing where to hook it up

you need a relay and a thermo switch.

AreExSeven

I did mine w/o a relay. If you don't wanna swtich it on and off manually just get an inline fuse and an electric thermostat. Hook one wire through the thermostat to a power source, and the other to the ground. Throw the fuse in there somewhere and you should be fine.

just run a relay and have it on all the time...

I have mine running a ground from the frame to the fan, then a 12v accessory power source and a inline fuse and a switch.

well thats cool but where do i hook all this up

hook your power to the green scanner connection located on the drivers side front corner...its a green 6 pin connector...connect it to the....middle plug...just try the middle ones..hope that helps...

On the fan motor there are two screws. Hook up 12v pos to one, neg to the other. I think you can reverse them to make the fan spin backwards. Anyways make it so the fan is sucking thru the rad. Then take a wire, a screw and 2 ring thingys. Take the rings and crimp them on each end of the wire. Put the screw in one and screw that onto the negative hole on the motor. Take the other end and find somewhere to ground that on the chassis. One of the radiator bolts should be sufficient. Now crimp a ring on another piece of wire, put that on the positive screw on the fan motor. Turn the car ignition to ON, get a dmm and start testing the plugs under the hood for 12v. There should be one at the passanger (I think?) strut tower for AAS. When you find 12v, turn the key to off and test again. Make sure its not constant 12v or itll drain the battery. Get a spade connector, crimp it on the end of the wire and plug it into the plug you found 12v at.

The only concern I ever had was about a thermo switch. How do you hook that part up exactly?

Scott 89t2

but then you have 10 amps going through the thermo switch.. which is not good. always use a relay for high drawing stuff.

weither you are using a manual switch (don't), a thermoswitch (do), or powered straight off a 12v souce (don't) you need a relay.

Scott 89t2

wait never mind I think most thermo switchs are built in relays

ight thanks i just wish there where pictures im more of a visual learner

rx7_ragtop used to have a site with pics but it's gone.

well buy a temp switch and it'll tell you one the back

dr0x

whats the website that sells temp switches, they also sell e-fans?

Bigretardhead

I went to get a thermo switch at napa (for my fiero fan ) and the guy tried to sell me one that bolted into the radiator?? is this the correct thing to get? I thought I was supposed to get one with the little needle thing that stuck into the radiator fins?

dr0x

There are a few different types. Id rather get the needle type than one that bolts into the tank on the radiator. Less work to install it. The one that bolts in youd have to make a hole for it and blah.

The thermal switch you can get at Autozone, it's called the Imperial (part# 226203), sells for around $16. It has an infinite dial adjustment to turn it on at a given termperature range.

Don't forget that the fiero e-fan uses a chasis ground. You will see a wire bolted to the stator housing that runs to where one of the fan shroud bolts go. Since you can't actually bolt this fan down (and utilize the chasis ground), you will have to run another wire from that bolt on the stator housing to a ground point on your car. I ran mine to the radiator tank supports.

If you are really lazy like me, Hayden sells an e-fan kit that will include everything you need; including the connection for the A/C clutch override.

If you go with the Hayden kit (or anyone else for that matter), it comes with a 25 amp fuse. When my car was sitting at idle, the fan would turn on and off with no problems. As soon as I started driving, I blew the fuse. I moved up to a 30 amp fuse and everything has been fine.

Some of you guys just shouldn't wire stuff up...

ALWAYS wire electric fans up to the BATTERY via fuse and relay. Never just tap into the first switched 12V supply you can find, because most of switched 12V stuff in the engine bay is very low current, and the wiring and fuse won't be suitable. Electric fans draw a lot of current (particularly on start-up), so should be kept seperate from the factory wiring.

Use a relay and DON'T USE the green connector to feed 12V to your fan. You can use the connector as a switched source for the relay and get 12V from the battery. A relay costs $5 dollars and takes another 5-10 minutes to install. Its not rocket science. Theres a diagram on the back of the package telling you how to connect it.

I once wired rewired the headlights w/ a manual switch and no relay. The switch really was going to be temproary. In about 5 hours of drive time from here to another city, the switch had literaly melted due to the 25-30amp draw. I endedup having to hardware the lights on the way home. Burnt my hands pretty good in the process too. If you ever want to see hardplastic melt in your hands...

Electric fans (in my experience) tend to burn up everything. Always use a relay and/or a heavy duty switch and wire it straight to the battery.

Amur_

I used 10-gauge automotive wire and the Flex-a-Lite temp switch, all wired to the battery, for my Fiero fan.

I'm a long way from being Mr. Electric Guy, so would someone please answer this question I have about what's been said - are you saying that adding a relay to the e-fan's circuit will ease the 'thump' on the charging sys when the fan initially engages?
