Yes, You need to get a new alternator with an electric fan. Just call a junk yard and see if they have any. Make sure you find out if the is a guarantee on it. Secondly, there are a ton of 3g alts out there on different vehicles. Do a search, a lot of cars have alts that will work on our cars. I know a 94-95 gt does, there are thunderbirds, f-150s, cougars, v6 stangs, and more. Good luck.

The 150a fuse will be good enough.I dont know it the wires are the same color as mine but the directions for my alt says LG/R"new plug" will splice into the green"fact plug"and the Y/w"new plug" will splice will splice into the yellow"fact plug"the white wire is not used.

I have a question about the fuse for the new 4 gauge power wire on a 3G Alt upgrade. I was planning to put this near the battery or solenoid, whichever I use for the power supply.

I read that some people are putting the fuse under the factory air box, which would make the fuse location closer to the alternator.

I always thought you wanted it closest to the power supply. Can someone confirm the best location for the fuse on the 4 gauge power wire from the 3G alt stud to the battery or solenoid?

Wish I had seen your post sooner since I just went thru this so I feel for u..I bought the alt. at pepboys, I asked for a 95 mustang alternator then checked the pulley and it had 5 grooves which matches my belt. The pulley is bigger than the 2g but don't worry because the belt tensioner will still be in range when u put the belt back on(if not change belt so it's in range).

I got the parts at http://www.partsexpress.com

I also ordered the Stator Plug from http://pa-performance.com

Price Each: $4.50

That's it man! just sit back and wait for the parts to arrive.
I put the fuse on the solenoid end about a foot or so then tucked it next to the battery.

I purchased a pipe and used it as a breaker bar, it made it 100 times easier to get the belt on.

All i need to know now is where to put the inline fuse on the 4 gauge power wire. Should I put it closer to the alternator, or closer to the power wire where it connects to the power side of the solenoid? I have read to put it both places. Which one would be better? Closer to the solenoid, or the alternator? Thanks.

I just use the a tire iron and wedge it between the tensioner pulley and it's body(where the range dial is) and use it as a lever - real easy.

I guess it doesn't matter where you put the fuse as long as you put one. I put it on the solenoid side and if you think about it, the fuselinks that were on the two 10 gauge cables that you're replacing are on the far side of the laternator..there are many diagrams on the web, here's one http://www.tffn.net/altwirng.html

Bringin this thread back to life

i'm going to do the 3g conversion here on my 88gt soon. would you guys recommend getting a new 3g alternator?... or getting one off a car at the junk yard?? i don't know how much it would be at a junk yard, $50 or something -- but i can get a new one for $170+tax at my ford dealer.. i'm afraid of a junk yard one acting up, since it will have probably been sitting for a while. tell me what you all think --

new 3g/junkyard 3g?????

Depends how long you want to keep the car. I know I will not be getting rid of it so I bought a 130 amp Boush at Pepboys with lifetime warranty. Think I paid about 160 with core.
