Electric fan upgrade?

[82LTDQS]

I want to do an electric fan upgrade on my below listed car. I pulled a single fan unit from a early 2000's CV. It has three wires. Blue, black, and black. I did not bother with any of the speed controler stuff. I just want to hard wire it in at full speed with an ON/OFF switch or just to the ignition via a relay.

Here are my questions: I tested it and its a monster. It seems to suck power and it uses THICK wires. I have the 3G alternator with a nice big wire to the battery. however, I wanted to make sure this thing wont kill my battery or something. ANY ADVICE????:smirk:

Well i wouldn't wire it on with the ignition, but on a switch through a relay. Your car needs all of the battery power to start itself and that would be a huge drain. This way, worst case scenario is needing to flip a switch.

Run it right off of the battery but relay and fuse it. Wire the switch/relay so you couldn't turn it on unless the motor is running...don't want it zapping all of the juicy juice they put in your battery when it was born.

now that I'm awake I realize to make sure it only works when the motor is running would be retarded easy, just feed the switch (on your dash or whatever) with key on power



what kind of voltage do these things suck up? I would definitely not be opposed to getting rid of the monstrosity thats cooling my engine. How difficult is the install?

I will take pictures and document this swap/upgrade. It takes 33 amps continuously from what I have read. Im gona need a fusable link and relay. From what I have read online, I gona need 10g. I will advise. I sow a vidoe some time ago where Im gona have to cut a bit off the shroud.

I always run them on my mud trucks. They kick ass. Not sure on the current draw. But it will keep a 351w running cool at wide open with a 1 core radiator under very heavy load and lots of mud. May want to put it on a toggle as your car may never get up to temp with one in the winter time.

Blaze has one on his vic....might want to ask him how he did it, or check out his cardomain or readers ride thread

i just don't know the size difference or the difference in mounting points etc.....what would I need to do with the belt if I got rid of the fan?

Nothing, just unbolt the fan, and re-bolt on the water pump pulley.

I have one also, but its an after market one. Its a 14'' cheapo from ebay and I have yet to see the temp guage get above half way. It only makes it to half way sitting in traffic when its 100 degrees outside. I dont even use it most of the time, the car runs really cool without it, I only turn it on in traffic or when im sitting and idleing, also for cool down between passes at the strip. Anyway I dont even have a relay I just used 14 guage wire ran it to a hot then put a toggle in the ground wire, you should always break the ground side btw it helps avoid voltage spikes. One of my favorite mods to date definetly recomend. On a side not you should probly use a relay if it draws 33 amps.

I hooked it to my bat charger and it pulls about 35 amps. I ust got a 40 amp fusable link and large starter type relay. Im gona hook it to the ignition AND have switch. Then I can turn it off and also not have to worry about leaving it on and killing my battery!

will it physically fit is a better question. Seems to me I tried stuffing a 98 fan on my car and it was way too thick. The Mark VIII, Taurus, and Continental (88-94) fans are much thinner and move a similar amount of air. They suck about 35-40 amps on high, but if you have a 130 amp alternator it should be OK. You will need a rather beefy relay though. I doubled up a pair of 30 amp relays to handle the load and its been fine for ~2 years.

Ok, Since I went to H.E.I, I used one ignition wire for the HEi (the thick one). And the thinner ignition wire I used for the on/off power for this fan. SO, its gona turn off when the key is off. NO DEAD BATTERY if I forget. I also have an on and off switch to a ford starter relay with a 40 amp breaker. All of the wiring is done. I just need to swap the fans. The fan is too thick. However, ther was this freaking video on youtube that is gone now. It was a video that a guy made on how to cut the shroud too make it thin engough to fit. I will try and find it.

Starter relays are not designed for continuous duty. Not sure how well that will hold up.
