Electric Fan Questions Reply #1 – December 17, 2009, 03:05:06 PM Well, one thing that I have noticed with some Mech fans, is that they tend to lock on first startup so you get a roaring sound until you get a little temp, so the electric fan eliminates that, so it's quieter. It also allows your engine to warm up a little faster, as the mech fan is always pulling some air through the radiator.As long as you install the fan correctly (Don't leave too much air gap between it and the radiator) and you have a properly functioning radiator a 16" should do just fine.Unless it's a really shiznitty fan, or one hell of a toggle switch, you CANNOT run the current for the fan directly through the switch, as most Efans draw 15-30 Amps continuous while running and up to 60 Amps on start up. Use the search function to find the wiring diagram using a relay and a temp switch to do it right. Summit Racing sells the whole fan controller at a pretty reasonable price. Quote Selected

Electric Fan Questions Reply #3 – December 17, 2009, 05:53:55 PM At the very least you'll need a relay to handle the amperage instead of the switch. You wire the switch to the relay, and the relay to fan. Quote Selected

Electric Fan Questions Reply #5 – December 17, 2009, 10:03:39 PM As far as I know everyone HERE(And that's a lot of people) that has done it, used the method with the relay.As long as it isn't a normal 2-5 Amp toggle, and it's rated for the amperage, then fine.But if the wiring melts down, and your car catches fire, don't say I didn't warn you.BTW, the fan swap has been covered in depth on this forum, try searching for the answer to your other questions.

Electric Fan Questions Reply #6 – December 17, 2009, 10:08:01 PM why would you not use a relay? its not much tougher or more money. and that will save you one day when the switch gets burned up and you have to drive home with no fan or worse yet, overheat the switch and a fire. those people either got lucky or just haven't used it long enough yet. theres a reason why high load devices get relays. its your car, but i'd never trust that without a relay in mine.

Electric Fan Questions Reply #8 – December 18, 2009, 10:30:47 PM for my electric fan setup i used one relay two 60 amp fuses and a super heavy duty switch and heavy duty wire. because i learned my lesson on cheap parts. i had a cheap toggle switch after 5 minutes of use it started melting the wires and the switch. if i was you i would use a relay and maybe a fuse or two to aleast not burn your car down. if you dont you might as well start caring a fire extinguisher in your car.
