Electric Radiator Fan Install simplified?
Looking to get rid of the clutch fan and shroud, runing some piping and itl be in the way. For now il be sticking with the stock radiator since its brand new. Il be using 2 14" fans, and basicaly what im looking for is the easiest, simplest method to wire them in. I want them running at all time when the car is on.
Il be upgrading to a alluminum rad with fanshroud later.
Can i tap into my fuse box? With those add a fuse things? Anyone have some install pics by any chance?
If you have any info on it please let me know id appreciate it, i did see a similar thread but i couldnt get answer.
Thanks

You could just run a switch and risk forgetting to turn them on, or add a relay to a 12v switched ignition source that will engage the relay once you turn the key.
As for tapping into an existing fuse I would not suggest that. E-Fans pull alot of AMPS and constantly running, may overload that circuit...eventually causing a fire.

I did it and its simple as can be. buy a radiator fan switch kit and it comes with a diagram. The relay will have 4 wires to wire up: one main power from the battery, one ground to the temp sensor, one power wire to a switched source {ie. a wire that's only how when the ignition is on, so the fans don't run when the car is off} and a power wire to the fans.
I have a aluminum supra radiator and shroud ( i put heat resistant foam between the shroud and rad to seal it and have optimum air flow} and just eBay fans. It performs great and doesn't over heat in hot Texas weather. Even with full A/C

I envy your a/c comment .

Great thanks, so something like this?

Now since theres 2 fans do i need 2 relays or will 1 be sufficient? And then i just wire it to the ignition or some sort so itl turn on with the engine on correct?

I have 2 of those installed, but have replaced the temp sensor with the switches on my dash.
Here are a couple pictures that will help you along. One being how to wire dual fans with a single relay (although 2 is more ideal, one will work) and a detailed diagram of the relay.

Ohh ok im starting to understand it a bit, thanks alot man
So there 2 wires from the battery running into the relay and only one needs a fuse? Bridge into the 10 gauge wire with the 16-18g with no fuse? Or is it after the point with the fuse
And the temp sensor could i wire that to the ignition or an accessory that comes on when the cars on?
I guess i want to hard wire it to the ignition

Man I was just wondering about this yesterday... I pulled the fan shroud from the car and was going to try and think how to repair the mounting ears which are all broke off so its just dangling there...but now I think I will just put it back... I Used the CL search function....lol. and looked at all the electric fan discussion and most of it was one sided with people saying it wasnt worth it..... then somebody mentioned using is300 electric fans which sounded like good option... is there any chance of improving cooling over the stock fan?
wonder how come noone ever did a writeup on this project...

Only reason I have e-fans is because of my engine swap and not wanting the bulky GM clutch fan under my hood. I have had e-fan setups in the past on my S13's that I regretted, and switched back to the mechanical fan. It all depends on how much time/money you put in to the setup to determine if its worth it or not.

As for the fans and shroud swapping over should be easy, but Im going to doubt that the electrical side is plug and play. Could be useful writeup though if you get it to work easily

Heres another question, i have to use 10 gauge wire for the battery wire to relays, and from each fan to relay correct?
I guess im a little confused on the wire gauge needed. And will 1 fuse be enough or will i need a fuse.for each relay. And what fuse size.
Or can i attach the 10 wire to the 14-16 wire? Even if id the 14 wire is 2 inches long? Will that burn it out,?
Or running a 30amp fuse through 14 gauge wire? But il be using 1 wire to power 2 relays, will that sort of even it out?
Now each fan is 80watt/12 volt, so thats about 6amps? So each only draws 6 amps? Thats wat the calculator said. but a larger amp fuse cause the fans to work harder/spin faster? Or what will more amps to the system make it do?
Sorry for all these questions lol, i wana make sure i do it right
