Taurus Fan Mod, Snowball Effects Realized
*Pebble is tossed down a snowy slope*
SO, I decided I was bored and needed something to do, and I read the thread about installing a Taurus electric fan with variable controller from DC Controls. I liked the idea, though I might save some horsepower or at least have a reallly cool fan...
*Pebble gets some snow on it*
So I installed it all. It took some love, but it's all beautiful. I highly recommend the controller, an excellent product which is PERFECT for an off road applcation. I mounted the fan to a "new" junkyard radiator with some custom aluminum bracketry and all, it fits perfectly. Pics to come in a bit, I haven't gotten around to it yet...
*Now a medium sized snowball rolling briskly*
Anyway I new I needed a new radiator for some time, I was just putting it off, so I got one since everything would be apart anyway. Then, I decide since everything is apart replace all the belts and what not, piece of cake (this project has already gone far and above the "projected" price I was thinking, but ok). With the fan installed, everything works beautifully- temp guage goes right under halfway and sticks, AC on or off, maybe a tiny wobble here and there.
*Large snow-boulder, smashes a few money trees*
So I have driven it around for a little bit and I get in, try starting the car and CLICKCLICKCLICKCLICK... Battery's dead
So I get a jump and drive home, and I can see every time I stop at a light, the battery warning light comes up and the voltage guage drops below the midway mark. I rev the engine, and the battery light turns off as long as the RPMS are up, and the voltage goes up to about half.
*AVALANCHE*
It's pretty obvious what's happening here, my alternator can't take it anymore and said "I quit!" SO, now I need a new alternator, possibly with an optima to go with it, and I'm thinking the MR2 alternator (can anyone confirm, is it 100amp or 170amp?) and I found a great writeup on how to install it on a 3.0 and all... SO, now I need to find one of these alternators FAST (this weekend) and CHEAP (under $150). Will auto parts stores have them that cheap, or are junkyards my only chance?
Anyway,
Fan Writeup and a dream- $Free
Taurus Fan $50
Variable Controller $115
Belts and Hoses $65
Radiator $125
Alternator $100 (I hope)
Battery $100 (Optima Red Top)
Finding out one $165 upgrade added around $400 of additional upgrades-
PRICELESS
This is the coolest fan ever!

Did you have the fan wired run at the slow or high speed?
I found low speed drew 10 amps and high drew 30 which is a bit much for the stock alternator.

Plus, it's HOT in Tucson right now, especially for around town driving.

Sorry to hear about your misfortune. Hope you find what you need at the right price. I have to ask, did going to an electric fan improve your vehicles performance? I've always heard E fans help save HP, but never heard any confirmations from people who have tried it.

The optima could be your problem... I have seen those cause problems on many factory alternators. The best battery you can get is a Duralast Gold. About the only "best you can get" item at AutoZone. The Optima batteries are the ones that stores sell to make money... they turn a good profit. But hey, they look cool, right?

TRunner- I don't HAVE an Optima yet, I'm going to get one. I just have a 4-year old regular old battery, so it needs to be changed anyway.
This writeup makes it really easy (just buy an extra lower bracket and weld some extra length on it...you'll see.)
Off-Road.com Write-up
As for can I feel a difference in power?
No, my "butt-o-meter" cannot feel much of a difference, except in maybe the upper end. But, I'm glad I did the fan because it DOES make my AC a LOT colder, since the condenser is getting a lot more air through it. This alone, in the Tucson heat, is worth it in my opinion.
I'm going to install the "Linear Indicator" that DC Controls sells (an LED that goes from green to yellow to red), so I can keep tabs on how fast the fan is having to go to keep up. My guess is a little over 50% most of the time, for stop-and-go. I want to be able to keep an eye on such things since most of my offroading is in desert and dune heat, so I want to know if there is a problem before something really bad happens.
Oh yeah, I ordered the MR2 alternator from Checker, $170 + 50 core, not bad for a 100 amper... I'll let you know how the install goes. This way my lights won't dim at idle either (which they have been doing lately, but my idle is like 500 rpms so...)

I have been using optima batteries since 97 and never had an alternator problem.I have two on my 02 with a 9000lb winch and stock alternator.Never a problem.I also use a power inverter to run a small aircompressor.

This is on my "must do" mod list for the future.
Hurry up and find me a fan bamachem!

I found it at a junk yard using www.car-parts.com, for about $50.00
Just look for a 1992 Ford Taurus Radiator/Condensor Cooling Fan, for the 3.8l V-6 (non-SHO), and select your area. It's easy!

the last option is the one?
