I posted this up in the maintenance forum But I dont seem to be getting any responses there. Do I need to remove the S/C to get at the alternator? It kind of looks like it but not totally. From the bottom by the filter you could get at the electrical connection. But I'm not sure if you can get at the top bolts properly.
Here is the link to my post. I have also posted up pictures of the S/C install for referance.

Any input would be appriciated.

Back in the day my alt died and I had to do this exact same thing

Yes you will need to remove the SC. It's only 4 bolts holding it down and a few misc items connected to it.
yes u do, because i had to and didn't want to. but, if you installed the s/c yourself, you're gonna be surprised how fast u can disassemble and assemble it. i think it took me like 20 mins to deinstall and another 20 to reinstall.

Whoops, I didn't see it was for a 2.4L, my post was pertaining to the 2.2L SC.

I did the install myself. I was thinking if the thing does crap out on me.
1.)Take off Belt
2.)undo fuel rail and pull injectors w/rail
3.)undo S/C bolts on top/bottom of S/C
4.)Try and move S/C out of the way enough to get at alt bolts. If I have to pull the whole thing out Ill have to disconnect all connections.
Do you have any other suggections.
separate the tb from the s/c, the two hose connections, the map, and yes remove the whole s/c. it doesn't take that much honestly.

This is true on the ecotec but not on the 2.4 since the charger is cast as one with the manifold. It sucks but you do have to remove it.

I corrected myself above, temp brain fart on my part.

You have to pull the fuel rail to get access to the bolts of the S/C.
Also I was thinking you could probably just remove the TB from the S/C and leave it dangling there. Then pull out the S/C. Then you dont have to disconnect anything except for pulling out the S/C to get a the alternator.

my quote was only for the "leaving the charger hanging" question. yes, fuel rail, brackets, belt, and that pita hose that goes near the a/c compressor are also included.

Funny thing was it didnt do it on the way to work this morning which is about 20 minute drive. Not once which is weird. Ill keep an eye on it on the way home tonight.
I dont understand why it would be dipping so much then just run fine this morning. It's not like it's summer out and I'm pushing the S/C alot and heating up the alternator.
Question: Isnt there a test you can do to test out the alternator. SOmething like you pull the battery terminals off when the car is running and the car should either run or die. If it dies then the alternator is bad. If it keeps running it's good. How can something be so half failure. Doenst make sense.
Regards,
Had to do this not 3 weeks after installing my 2nd charger...that sucked
i think it was on like the hottest day of the year too, which sucked even more.
14.330 @ 96.37mph
Well the car seemed to run fine on the way to work this mornind and home tonight from work. I have to go out later to the my parents house. Ill see how she's runs over there and back.
Alfredo turbokav had another idea in my post in the maintenance forum. See link above. He said it could be the wire from my alternator to the battery. If you look at my S/C install pictures. You can see that wire goes to my starter then it looks like to the battery. Also you can see that there is some tape on that wire as well.
Anyway, I'm going to keep an eye on it over the next couple days.
I cant speak from personal experience.... but i took my car to a local shop and they told me my Alt was going bad. So i told them to change it while they had it in there.... They called me back later saying that they had never messed with a SC like this beofre and were afraid to touch it... and said if i was willing to approve a lil added labor time, they could try and get it out without touching the SC.
They managed to do it.... got new one in, worked fine for a few days... then the NEW Alt crapped out on me... so took it back and they had to do it all over again... this time free of charge.
They claim they never touched the SC for fear of hurting it. So there must be a way to do it.... they did it TWICE
hmm i was thinking about it the other day
would it be possible to unbolt the mounts and jack up the engine to get to it?
im sure if it was your guys would know about it, i just forgot where the alt bolts to the block
Ken, Navycav3,
I dont think it's that easy. If you look at the pictures from my supercharger install in the link above. It looks like one of the bolts of the alternator is right under one of the supercharger intake runners (closest to the timing chain side). So I still believe it has to be removed. I think that bolt is probably pretty damm long. I would have to take a closer look at it under the hood of my car.
I would like to know how they did it if they didnt remove the S/C.
yeah youre right, the runner is right in the way
thats what i thought just wanted to throw the idea out
I am going to be replacing the alternator on my car while it is strapped to the dyno. I am doing this to document the increase in power from the md-ld9 pulleys. And would prefer to just install a new alternator with the new aluminum pulley. From my experience I honestly do not think it is possible without pulling off the sc despite what they told you Ken. Even if it is I think it would be just as easy to remove the sc. I will share at that time how long it took me and take a good look at if it would be possible without removing the sc.
