  • The Valeo units have what is called a "floating stator", meaning that when the unit is assembled the rotor is not pressed into the alternator castings like a conventional alternator, but is placed/centered in the housing and held in place by the pressure of the through bolts holding the entire assembly together. If these units are dropped, or are subject to pressure during installation,the stator can actually shift slightly which will cause noises that range from a magnetic type 'hum' to a metal-on-metal noise.

Broken alternator mount

Showing 3 out of 9 Posts | Show 6 Hidden Posts
Question From jackslap on Broken alternator mount

Hello everyone, Way2old may recognize this as it is posted elsewhere but I thought I'd ask here in hopes for a quick response...

This is a 95 Chevy G20 van 5.something liter. Back in the middle of summer I replaced the serpentine belt and I noticed a small crack at one of the bolt heads. It seemed like it could have been an edge between two pieces of metal, sort of a joint of sorts and so I decided to just keep my eye on it. Granted it's a weird spot for a joint to be, but I left it alone anyway.
So now it is cracked in two spots, that original one I just mentioned and now a HUGE one over on the opposite side. The alternator is just dangling in place and wiggles around quite freely now.

What I'd like to know, what my manual doesn't show me is how the hell to replace that mount. It is one big piece of metal that seems to be part of the engine itself. There are no easly visible mounting points that I can see anywhere (I haven't really tore into it too far though). It almost seems as if a new peice of metal will have to be welded to it in order to get it fixed, but I'm sure that is not the case. Here are a few photos. Can anyone start me off in the right direction or should I just take this thing in to a mechanic tommorow.

BTW, my level of experience is moderate. I've done a lot of my own car repairs over the years to include water pumps, alternators, radiators, wheel bearings and seals, rear axle replacement, brakes, installed my own car stereo. Is this something I can handle in a few hours? If not, I'll just pay someone.

Response From Sidom

That was/is a common problem on those. The whole bracket has to be replaced. It's actually not as bad as it looks. No special tricks, just take a common sense approach to it, but pretty much everything has to come off.

Response From jackslap

By everything do you mean all the pulley devices? Water pump, AC etc... I think I'd have to pull the radiator out to get to all that stuff, what is that part even called? How would I know what to buy is what I'm asking?

Can you estimate what it would cost to have a mechanic do it instead?

Response From Sidom

Yes you have to pull all the accessories but not the water pump or the rad. Man it's been a while since I've done one of those. It paid like 2 or 3 hrs. if I remember right? After you did a few of them it was real easy to beat the book on those.

Response From jackslap

Lol, you're saying all this as if this is ancient history....sad but true I guess. Not many of these things floating around anymore.

Two or three hours mechanic time translates to probably 5-6 hours maybe more of my time. It's cold, rainy, I don't have a lot of free time this week or weekend, plus I have an extra 500 bucks coming this paycheck.

Christmas is just around the corner though....man, what to do what to do?

Do you have a part name? I looked up "alternator mounting bracket/plate" on a few parts sites (autozone, kragen) but only came up with a little curved bracket device with a couple of screws, not the right thing...

Response From jackslap

So I found this:

http://www.oehq.com/...G20%20VAN%205.7L.htm#

It is listed as a 1991 G20 5.7L, but I have a 1995 G20 5.7L...will this work? Is this even close to what I need or am I way off? I really don't want to tear into this thing if it's going to be a huge multi-day headache. I would just pay someone if it isn't outlandish.

You said it paid 2-3 hours...figure in parts and I'm out what 400-500 bucks?

Would I need any special tools, gear pullers, pully removers etc. or is this just a standard socket and wrench kind of job?

Response From way2old

Hey jackslap. If you need to remove a pulley, the power steereing should be the only one. Some parts houses rent tools for free. You leave a deposit and get it back when you return the tool. The only other problem I can remember is some of the bolts might be brolen and need drilled out. Other that that, one good afternoon and a few beers when done feels real good.

Response From jackslap Top Rated Answer

BAM! Got this mofo off...I decided to just do it myself and save a chunk for Christmas. Pretty easy going so far. Only had to remove two alternator bolts, two idler pulleys, and the wheel tensioner. Nothing else was attached to this. Whew! Now I just have to find the damn thing, nothing like the picture that I posted earlier. It's more like a "mounting shroud" or something...







Dealers are closed for the night, maybe I'll try Kragen or Autozone armed with this new information. Or I can google those numbers.

Response From Sidom

Glad to see you got it handled Jack. That's not the bracket I was thinking of so you lucked out

Those look like casting numbers so they may not be of much help but you shouldn't have to much trouble finding it, all though you will probably be limited to the dealer or wrecking yard for that part......

Naw.....not ancient history but you did make me think that it's been a while since I've done one the ones I was thinking off.... use to do them all the time, they'd crack, let the alt tilt & throw the serp belt....

  11. A/C splash shield from cradle (3 bolts).
  12. Access panel from bottom side of radiator support (4 bolts).
  13. Engine harness clip from cradle.
  14. Alternator from vehicle. The alternator can be moved out away from the engine and removed from the bottom side of the engine compartment.

Question From bolt buster on ALTERNATOR LT ON

1970 PONTIAC LEMANS ALTERNATOR LIGHT ON ? CHEV 383 CI AUTO

Response From Hammer Time

What have you done? Have you tested the charging voltage across the battery?
What is it?

Response From Loren Champlain Sr

Hammer; That would be an internal regulator. Didn't those years have a diode, up under the dash, that would go bad? Maybe, it was a relay....can't remember. O.F. disease.

Response From Hammer Time Top Rated Answer

Nothing I'm aware of. The diode is internal to the alternator as far as I know.

Response From bolt buster

TESTED BATTERY 12.60 YOLTS BACK OF ALTERNATOR 12.62VOLTS UNPLUGED CHOKE WIRE TO CARB LIGHT OUT

Response From Hammer Time

If you got those readings with the engine running, then the alternator is not charging. I can't remember if that year had an external or internal voltage regulator. If it's iinternal, then change the alternator. If it's external, then you will have to full field the regulator and test it again.

Question From stijnw on nissan cd20 alternator

hi,

i'm working on a old nissan engine(cd20) from a sunny,
i found a component outside of the alternator,
but i don't know for what reason it's there...



can someone help me with this ?

Response From Hammer Time Top Rated Answer

That's just a capacitor that is used as a noise filter for the radio. It filters alternator noise in your AM radio reception.

Response From stijnw

ah ok thx :D

Question From alexs 86z28 on alternator wont charge battery.

i have an 86z28camaro i'm having problems with the alternator not charging the battery, i had the alternator checked at auto zone 3diff, times and it pass as good everytime its a new alternator.

Response From Tom Greenleaf Top Rated Answer

Are you suggesting that it tests good and doesn't work in the car? They may be testing it by, bypassing the internal regulator and it could charge that way as a test.

Regulator should be available separately if you are up to taking the alternator apart (doable if you pay attention) and isn't that expensive for this era - (famous last words) if what I searched was correct.....

Test shown was like this.....

****************

On some internal regulator AC generators, full-fielding can be done by inserting a screwdriver through a special hole on the back of the unit.



**************

If exactly like that and you have room you could test it on car yourself.

Are you replacing this all the time? That isn't right if so,
