I had to replace the Alternator in my 87 Gt. It was charging fine but it also was sucking power from my battery when the car wasn't running. After about a week of not running the battery was dead. New Alternator fixed it fine. But I left the 5 ridge pulley on it and it ate my drive belt after about 3 weeks. After a new drive belt and replacing the pulley with a four ridge one, everything is great!

thanks man - great content will check my 'heater resistor box' in a couple weeks when i pull my 87GT out of the garage.

It's nice to see someone actually replace the alternator properly in a 2.8 2M6 Fiero! I have one question though, what happened to the heat shield that was on the alternator when it was stock?

I'm going to be replacing my alternator before spring too, mine is making scraping sounds, and last fall it wasn't quite working like it should. I'll be upgrading to the '88 cs130 alternator, it's a better, more reliable unit.

Nice video again Kyle, love it. Hey I might have a question about music attribution to you. Will post it in the FB chat.

I thought this was gonna be this straight forward on my 87 GT auto. nope. upgraded from stock to 140amp powermaster from the fiero store so i didn't have to worry about losing charge while stopped. it MOSTLY fixed that but took forever to get it working, found out I had to go with a single 1 wire setup to the alternator and leave the alt plug free. i don't really understand why that is but when I had it plugged in, the car wouldn't even crank.

Luckily you swapped to a manual, this is significantly harder on automatics. I kept having parts store alternators fail, so I stopped buying them and started rebuilding them myself. What did I find on the first one I cracked open? Loose parts. That was in a fresh "remanufactured" unit from the green store.

You lucked out getting that top bolt 🔩 mine was frozen had to remove the whole bracket lift the engine gave it a slight tap and cracked the bracket 😮 on my way to the salvage yard 😅

My alternator on my 86 absolutely screams on a cold start. Its original and I think its time for a swap. Might as well get to that squeaky belt while im at it. 😅

I want a pontiac fiero SOOOO BAD

This exact same thing happened to my Fiero, maybe it's a common problem.

What alternator did you use for your fiero?

Acdelco sucks. many defective returns.

I can not speak to other than an 88. Disconnect all but the wires. just drop it down thru the gap where the tierod is in this video. I rolled mine up onto the oil change ramps which left more clearance.

You have to keep the ribs the same. otherwise you will eat belts. I have been doing this and other fixes since 1992
