« on: January 28, 2009, 03:20:23 PM »
i am about to buy a used flex a lite electric fan. I was just wondering how everyone was wiring it. I was thinking just putting it on an on/off switch but im not sure what the best way is.

Wire it with a relay for sure.  You don't want hi-amps running though to the dash anyway.  Use at least 16 gauge wire as well.  You can run 14-16 from the battery to the relay and fan then run something like 18-22 to the dash since it's lo-amps.  Get a good switch.  I'd look for AC toggle switches since the DC automotive selection is usually crap.

autozone and advance auto have

180 degree on, 170 off kits, they have the relay and both sets of wiring ready to go.  the thermoswitch goes into fins of radiator

temp sensor goes in teh cooler part of the rad.

$80... is it posible to just get the 185-170 thermostate add get your own realy and peice one together for less.../ how does the thermostate work? does it send out a signal that has to be read or does it just alow current to flow when between the 2 temps( looks to me like the  kit is jsut a relay, the thermostate, a circute breaker and some wires)?  sorry for hijack but i figure that this may be helpfull to more people than just me.  (sorry for any spelling errors no mozila on this computer)

yes, u can bye all seperate, thermoswitch, relay and wiring, or you can buy the whole group and save soldering and fuse work and ALL that time.  just a suggestion.  go to autozone and check them out.

http://www.dccontrol.com/0820.htm  The FK35 would be a good fan controller for you.  It varies the fan speed for the specific engine temp.

thing is autozone isn't in my town and online it says they don't stock it so you have to get it special ordered... so i might just order online and be done with it.

ok so now that i have $$ im going to order one... what temp should be used. the 185-175 or 200-185... the thermostat is threaded in if that makes a difference becasue it will read from the block / intake rather than the fins of the radiator.

It also uses less amp, as it does not turn the fan ON all the way but rather does a soft start (speeds up gradually); something to consider if you are running a stock alternator...

Check DCC's shipping times. I saw on another board that they ordered parts from DCC and it took months for them to ship.

The website did say they needed a 10-day lead time due to demand.  Prolly varies.  I contacted them via email and received my part in a timely manner.

Well worth the wait on the DCC fan controller.  Very complete, all the wiring and connectors I needed, and works very well.  Very happy that the fan only spins as fast as needed, definitely minimizing the current draw.
