I have an 86 burgandy fleetwood brougham and when i start the car it does a quick whine for a second then runs normally. It just started doing this and it's pretty quick. Anyone have this problem before or know what it is ?

Thanks

I don't think it's the belts because I hear that to on a wet day. I have no clue what it is and it's starting to become more noticeable. Someone told me it could be the alternator I was just hoping someone out there has had the same problem. :banghead: It sounds like Injectors going but it's not fuel injected that's for sure. Like a fast whine and I am starting to notice it more and more I am just hoping I can keep this beast alive it's my normal day car :lildevil: I have no clue what it is, I just want to be prepared for the worst lol


Thanks

Hello.
By your description it seems that it is a bearing in one of yours engine accessories, like the subjected Generator, but it can also come from the waterpump,
AC-compressor, servopump, or the thermoclutch on the fan if the car is equipped with that, but most common is that it is the generator.
How to find out? With the engine off, try to feel if you can feel any radial movement when you grab the accessories pulleys and (shake) them. Due to the belt tension is it often hard to feel any fault in this manor.
An alternative is to loosen the belts and try then, but it is better to first try this:
With the engine running, grab the biggest screwdriver you have, hold the handle to your ear, and put the tip of the screwdriver, on the suspected parts housing, beware of moving parts.
If it is a bad bearing it should be like a grinding sound compared with others.
There is a special tool for this instead of the screwdriver, and that is similar to a doctor’s stethoscope and is of course better than the screwdriver, but not too many have such a tool in their garage.
It would be best if it was the generator, cheapest and fastest to fix.
Good luck.

I'm thinking its the bendix drive on the starter. Sometimes they wont slide back after the engine starts and spin with the starter causing a whine type noise. You might try placing a piece of garden hose on the starter then to your ear and have someone start it. Might have to be done from underneath? If in fact thats the noise, then either replacement of the starter or shimming the starter will fix it. Good luck!

Alright the problem has gone form a whining noise to like a wet belt squealing noise. Also today when I started the car first start in 2 days it started then died saying no charge. The noise is coming from the part circled into pictures. I'm not to sure what it is but have feelin it is the alternator. Let me know what u think.


This one is a closeup of it . The sound if coming from here .

My LT1 is doing it now, alternator front bearing. To be swapped very soon here....

Olds V8's are notorious for power steering squeals. Check that too like Katshot said. It is easy to have a loose belt there. But get an automotive stethascope and listen around. A screwdriver, rod or extension isn't sensitive enough and precise enough. The are cheap and an invaluable tool. I found a broken piston with an automitive steth. A 3 foot extension couldn't. But for this excersize, the extension or screwdriver should work. But the steth should be in everyone's toolbox.

If you think it is the AC, pull the belt to isolate. Not exactly fun on an Olds V8, but doable.

hmm if that's the ac compressor then that's deffinately making the noise. Does that run even when the a/c is off? I run the heat a lot now that winters around and it makes the sound with or without it on. I'lll be attempting another start tonight and a drive to work lets hope I make it !

The compressor will generally run whenever the climate control is in "AUTO" or when you select a defrost setting. If you have it on "ECON", the unit will not be on. If the noise is coming from it even when off, look for a slipping belt or possibly a dragging clutch. If it were to make a noise constantly, I'd say look at the pulley bearing.

It's been raining for like a day. I go out and start the car no problem can't even hear the noise. It does sound like a bearing gone noise though it would make sense. That belt there goes down and hooks up where the fan is and that's how it gets pulled when the motor is running. I'll try it today with econ on and if that thing stops moving and the noise stops maybe i can narrow it down. Starts normally now so I don't think it's the alternator. The Check Engine light has been on for a year and it makes me crazy. I changed the oil plugs / cables and air filter. Think changing the oxygen sensor might get rid of it?

thanks

yea the inexpensive way sounds good. I ran the car with econo and the a/c still moves. The noise has weakened now and seems to have faded. How would I be able to read the codes?

thanks

What part of it moves? The pulley part that the belt is on will always move unless the engine isn't running. Do a search and you'll find some posts that say how to read the codes.

I read up about checking codes just a little confused on ODB and ODB2. Which one would I use on the 86 fleet. From what I gather there to different types of connections????????

Thanks

Excellent, now all I need to do is locate the diagnostic port and I'm good to go. Thanks a lot for the help.

You think any old OBD computer will work as long as it's not version 2 right?

I don't mean any old piece of garbage lol I'll get one that works. I'm seing the OBD II more around then the original version. Ebay was my first shot @ it.


Thanks,
