alternator replacement (Page 1/2)

Okay, so a few days ago my fiero's alternator crapped out on me, so i bought a new one, and i have a good understanding on how to replace an alternator, but I just want to know if y'all have any tips/tricks to make replacing it less of a pain in the a$$.

It's a "pain in the a$$" when people don't describe their Fiero when asking a question. And yes, it makes a considerable difference with an alternator replacement.

Ouch! Geez, Patrick, cut the newbie a bit of slack.

Patrick is right. It depends a lot on your car but if you search the archives or go to Ogre's Cave you should be able pick up all the data you need. There are a couple of step by steps around. Chances are you'll have to come in through the right rear wheel well after you pull the plastic inner liner. If you have a pre-'88 car, you may want to upgrade to a CS-130 alternator. It's well worth the effort. Fierosound has a good how-to in the FAQs and how-to section (http://www.fiero.nl/forum/Forum9/HTML/000035.html).

If it is a stick or auto the replacement job for an alternator on the V6 engine will vary . The auto is more difficult as there is less room to work. If you have an auto the alternator can be taken out from the right wheelhouse as Mike has said but its a bit more involved than that. I've only done one but I recall having to remove both the alternator and the mounting bracket for enough clearance to get the alternator removed and installed. If you have a stick the process is much easier.

I apologize for not putting enough info, I didn't know it varied that much for each fiero. It is an automatic (though i plan on swapping it because it used to be a 4 speed) and it is a notchback, and it's an 86. Thank you to Mike and Dennis for helping. will definitely be going through the right rear wheel well. I will post pictures of the car in future posts, so that way y'all can see the car. I'll try and fix her today, as I get my driver's license tomorrow. (i'm 16)

No apologies needed. People who are on this forum are here to help. That is part of the enjoyment of this hobby and the young guys like yourself are the future of it. Good luck with the car, It is 34 years old will require some TLC . I'm sure that you will have fun with it while asking more questions.

It's a V6 right?

Like Dennis said, it is helpful to remove the bracket and get it out of there and out of the way.

It's like pulling teeth!

Interesting how everyone has assumed that this car has a 2.8... and not a 2.5... or possibly even a swap.

86fierorestoproject... in the future please mention the year, engine and transmission that your Fiero has when asking a question, because no, we're not all going to remember.

yes, it is the 2.8 V6, and we got it out, but boy was it a pain. we are gonna put the new one in wednesday as i am gonna get a new belt tomorrow. Thanks to everyone for the tips!

If you have time....check into the dodge runner belt tensioner / belt conversion. Solves adjustment issues, squealing etc. A second alternative for squealing and it does help with adjustment is the Rodney Dickman idler pulley.
