Hello guys

 

I have been having this same problem with my sharan 1.9tdi, got my alternator pulley sorted out thanks to this thread but I have a problem with the bracket that holds the tensioner wheel, where the bar goes through the alternator mounting bracket there is a bush, mine has lost this bush and I cant find a part number anywhere or a replacement bush. Does anyone out there know the number for this or if not then the dimensions so I can source a replacement part. I have attached a photo of a good one

Hi,

 

6 months ago I fitted a new tensioner with a new belt, all seemed ok. Then about a month ago the belt started to squeal again. Having looked at the belt while the engine was running, the tensioner was twitching all over.

 

As i didn't buy a genuine part I suspected the tensioner and changed it again but the squeal was still there at full lock!!

 

So havin read the post from "littledaz" last night I contacted Ford for a price, they said I had to buy a new alternator!! So I removed the alternator and took it to local alternator specialist who fitted a new pulley and tested it for

It seems that quite a few of you are suffering from this. From the description of your symptoms, this sounds identical to the issues that I have successfully rectified on Audi models at my Audi dealership that share the same engine.

 

First of all, this mainly affects the diesel models as they are the VW group engines. The noise is due to the ribbed v belt bouncing around on the pulleys thus loosing grip and creating a squeal. The reason the squeal is worse when turning the steering is due to the heavy load from the pump. Anybody that thinks the alternator is the cause is correct, well almost. The faulty component is actually the alternator pulley. It has a one-way clutch built in to the pulley which allows the alternator to freewheel in one direction. When this pulley seizes, it causes the belt to load up on the tensioner side causing the tensioner to spring back. This effect then causes the belt to be slack in certain places, mainly at the power steering pump area, causing the noise and rough steering feeling. You can usually view this by the tensioner bouncing around at tickover when it should be steady. The more load on the belt, the noisier it will be i.e. on full lock.

 

There is good news and bad news.

 

The good - the pulley is available as a separate part ( about £50 at VW/AUDI/SEAT dealers, not sure about Ford).

 

The bad - the pulley requires a special small spline tool to remove it and is fairly tight.

 

 

There is a check that anyone with a small amount of technical know-how can do.

 

1. <b>Disconnect the battery</b> (we don't want any thermal incidents from shorting the alternator).

 

2. View the alternator from above.

 

3. Identify the pulley end and look through the ribs of the body of the alternator.

 

4. Identify the alternator fan blades which can be seen through the ribs.

 

5. Insert a small electrical type screwdriver in between the ribs and try to turn the fan clockwise and anticlockwise.

 

6. If the fan turns freely in one direction and tries to move the pulley in the other it is OK.

 

7. If the fan tries to turn the pulley in both directions it is faulty and is causing this issue.

 

N.B. The fan does not require much effort to freewheel.

 

 

 

Another way is with the alternator removed.

 

Lock the alternator fan with a screwdriver or similar and try to turn the pulley in both directions.

 

If it freewheels in one direction it is OK.

 

 

As I said earlier, I have rectified many Audis with this issue.

Rarely does the belt or tensioner need to be replaced but, consideration has to be given to how long you have endured the issue. If you find that your pulley is faulty and have the ability to remove your alternator, you can greatly reduce the costs in diagnosing this issue and save on unnecessary replaced belts and tensioners.

 

Hope this info helps you,

Hello everyone! I just bought ford galaxy mk1 1997, 90hp, and now I'm expierencing awful screech noise while turning the wheel when a car is not moving, but engine on and while driving very slowly. Also I feel that the steering wheel is shaking a bit while doing this. First I thought something might be wrong with the power steering, fluid (its ok), belt, tensioner, pump?, but then I found this thread and littledaz instruction. I wanted to check it by myself, but I cant find alternator fan blades, I just cant see them through the ribs. Frankly I dont even know where to look... on the back or on sides of alternator ? I took some pictures of it so you could point a finger where to look for those blades :wacko: This is my first car and I dont know anything about engines, but I always want to fix everything by myself. And I bought a book "I fix my car by myself - Ford Galaxy" :)

 

Any help would be greatly appreciated.

 

So...

 

This is the damn thing, example picture from another car actually, other pictures are showing mine.

...but mine has different label :

and that is the infamous pulley i think?

and the back of my alternator

hi all, just wanted to pass on my thanks and appreciation for all the advice on this topic. I have just performed this fix on my 2004 Alhambra and it has worked a treat, took just over an hour not very difficult and replacement pulley purchased from GSF (cardiff branch) for around

Hey all.

Ref - Galaxy tdi 130bhp 2003 location - Dundee

 

Result.............like everyone else, tensioner noisy.

2 years ago, as part of service, Ford replaced the aux belt and tensioner.

OK for a week, then they wanted to change the power steering pump. Declined this as they couldn't guarantee a fix.

 

So, I changed this myself and then the power steering rack.........still not sorted.

 

As you can imagine, well pissed off, until I saw this thread last week.

 

Purchased tool kit from fleebay, and pulley from local factors.

Fitted yesterday.......result.

 

Well pleased.

Hi guys

 

I'm pretty sure my TDi is having this problem. Mechanic has checked and I don't have the 1 way pulley - he also checked with Frauds as well (don't have part # to hand).

 

I need to catch up with him but before I do, could replacing the pulley that I have make any difference?

Don't think you can get the pulley on it's own from fords.

They are available from motor factors but you will need the special bolt removal tool.

Better still if you have a alternator/starter repairer near you take the alternator off yourself and take it to them they will usually supply the fit the pulley to your alternator.

I too have the 'rumbling noise' under the bonnet and also extremely heavy power stearing when the car is stationary and idling, but becomes lighter once the car wheels are moving slightly or with higher revs. An additional problem I have is that the battery drains if the car is unlocked for more than 60 mins or if the ignition is on in the final position for about 20 mins.

 

Do you feel the battery issue is also a symptom of the alternator belt issue (writing this now it would seem so)

 

Thanks,

 

Angus
