HISSIN50 said:Jerry Beach used to run a 3.8L Taurus fan on his 2G with a toggle. He said that he had to monitor what accessories were on and he only ran the low speed (which was more than enough with his 3 core rad, even in humid Florida). he has since gone with a variable controller (same set up as SGarlic)
I only posted that since you asked and he is busy lately and does not come in here as often.
good luck.
jrichker said:Electric fan = 3G alternator if you want long life & reliability from your car.
The electric fan saves some HP. The stock fan's parasitic drag runs from 7-12 HP depending on who you talk to. The electric fan uses about 1/2 HP of power from the electrical system.
Figure this:
Ignition system & computer = 12 amps
Fuel pump = 12 amps
Exterior lights = 15 amps
Fan (heater or A/C) = 15 amps (can run between 5-25 amps depending on setting)
Radio & instruments = 10 amps
Wipers = 10 amps
That's grand total of 74 amps from a 65 amp alternator. Talk about overdrawn at the bank!
Here's websites with pictures of the 3G installation...
See http://www.geocities.com/smithmonte/Auto/3G_130A_Alternator_Upgrade.htm - all the tech data you could ever want to know
OR
http://www.mustangcentral.net/tech/alternator.html - excellent pictures of installation
Use these sites for information on the right way to do the wiring. Some people will tell you that you can skip the wiring upgrade, but it will catch up with you sooner or later. A fire in the wiring harness is ugly and expensive.
Under no circumstances connect the two 10 gauge black/white wires to the 3G alternator. If the fuse blows in the 4 gauge wire, the two 10 gauge wires will be overloaded to the point of catching fire and burning up the wiring harness.
See WWW.partsexpress.com for the fuse & fuse holder.
Fuse @ $3.90 each (need one) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=071-952
Fuseholder @ $5.80 each (need one) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=263-630
4 gauge black wire @ $1.25 a foot (use string to lay out routing & determine length) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=100-196

I do have a new alt. and battery though.
MarSaleenMustan said:I was wondering if a junkyard electric fan would work with the stock fox alternater? i know its recomended that you upgrade to the 130 amp, but is it possible to make it work considering i have a stock radio(aka no sound system) and manual windows/locks on my 88? not to mention no AC(if it matters) including no fan box from under dash. i'm not looking to do a DCcontroller setup, just a simple switch inside and a simple electric fan.
MarSaleenMustan said:Actually just lastnight at work(i work for autozone) i went back to where we have all the cooling stuff, like electric fans, fan blades ect. and noticed there was a kit too, it consists wires, a relay, and a sensor that you feed through the radiator, it goes for $21, so with my discount i'm looking at $16, not to mention there was another kit which was adjustable, i didnt open the box to see how exactly it works, but it was priced at $17. I think i might get atleast the $21 dollar one.
yeah its an Imperial, so what about the AC line deal? i dont have AC.Biggeley said:I really like the autozone (hayden or imperial brand) non-adjustible one.. It comes on at 180 degrees and off at 165 degrees.. The probe is nothing but a copper rod that slides through your radiator fins and then has a non-adjustible temperature switch that screws into the end of the rod. Simple design, very reliable and has been extremely consistent. Has a diode for attaching it to your AC line. And only 20 bucks for the setup. The 30 amp relay should be good for lower-powered fans but I upgraded it to a 75-amp relay to run my taurus fan on high.
i dont have heater/ac, not even the fan box under the dash, so i'm hoping that helps.Biggeley said:I used an 89 3.8L taurus fan with a stock alternator with no problems. I just used the 'low' setting on the fan and used it for several months. It put quite a drain on the system when the lights or the ac/heater fans were on as well, but I never was left with a drained battery.
