need help with e-fan....calling all electrical guru's..

hey guys!!

ok, heres a ? about the civic...

the guy that owned the car before me removed the stock fan, and replaced it with a e-fan...thats fine by me

well...he has it wired up to a togle switch on the dash for it to come on and off...U have to chose it...

how would i go about wireing it up, so where the fan would kick on at a certain temp, and kick off at a certain temp, as to not drain the battery or etc, yet cool like its supposed to?

thanks guys!!!

I'd be willing to bet that every Civic ever made came from the factory with an electric cooling fan, wired to a thermoswitch in the cooling system or controlled by the ECU. Take a look at a shop manual and just make use of the stock controls that were engineered for that car and are probably still there.

ditto, if you cant find anything, get an aftermarket controller, i could get you one, but it would be better to wire it up the factory way

As a quick fix you can get a relay and wire it up a switched power source. That way it is always on when your ignition is on. But....It would probably be better to do what they said ^^^^^^

More than likely the switch that controlled the stock fan failed, and he put the switch in to control it.

I believe the stock system has the switch going to a relay to control the fan. Find that switch and replace it and you're part way there. He may not have even removed it and replacing it may do the whole job if you're lucky.

Why get an aftermarket one when the thing only needs the thermal switch replaced? Makes no sense to re-engineer it.

only reason i suggest it is because it may take days to figure out what part he needs, order it, and get it to work, and see if thats the right part. or he can just a universal controller and do it and be done.

I agree that the right way is to get the factory system to work again, but if it were my car, and I didnt want to stress about it, i would just get an aftermarket controller

I don't change things I don't have a reason to change. I'm just not that much of a masochist. I didn't add an efan until my stock one failed, etc. In fact, almost all the mods are I have are enhancements to fulfil a "need" I have (or think I have, lol...)

If you find the original wire (assuming it's a one wire switch) and ground it, and the fan runs, get a switch. Heck, you can get 'em almost anywhere.

If it's a two wire switch, short 'em together.
