Car has developed a noise which seems to be coming from the PULLEY area on the front of engine.
Im no expert but at first i thought it could be air sucking in somewhere but i am sure now that  it sounds like a bearing on one of the pulleys.
So question is is there a common fault with any of the pulley bearings so i could determine which it is likely to be

[GPar]

Almost certainly the bearing in the auxilliary belt tensioner pulley (top left as you look at the front of the engine). Common problem. About £30 to replace and 5 mins to change. You will only need the bearing/pulley, not the tensioner itself. Don't leave too long as the thing can sieze and leave you stranded.

Drop belt off and check all pulleys by hand.  Agreed most likely tensioner pulley (£24 on TC) - to swap undo 15mm nut, remove pulley.  As Haynes says refitting is reverse of removal!!  5min job

Dont buy a new one mate,just remove it and grease it using the black high temp stuff,like i did,job was a good un.

Agreed. If the bearing is caught before it wears too much, just prise the seals off carefully, pack with grease and replace seals.

A tensioner, washed out and re-greased seemed fine. Coule of weeks later it failed, slitting the aux belt lengthways. The flailing belt got between the cambelt cover and the backplate and derailled the cambelt. Result... 24 bent valves and two scrap heads. Is it worth the risk?

If its making a noise, its worn to much....replace.

If its just dry when you do a cambelt then re-grease

[hoj]

Well it turns out it was the tensioner as its just thrown the belt off and the plastic bit has dissintigrated.
Towed back to local garage now awaiting price.
Have been told i can just get the pully £20 or tensioner £60 but dont understand why i wouldnt need the tensioner???
Anyone

[Marks DTM Calib]

Because the tensioner is a sprung assembly with a pulley mounted on the end of it....the puley has failed so replace just that....the tensioner wil be fine

[hoj]

what is the plastic bit attached to - the new pulley i presume

[Matchless]

The plastic bit is the pulley, there is a bearing inside and the pulley is moulded around it.
Undo the 15mm nut in the middle, take off the old pulley, fit the new one, do up the nut and refit the belt.
As simple as that.

[GPar]

I won't say told you so ......oh damn, I just have! Did try to stop you driving it as exactly the same happened to me including the recovery bit. As already said, you just need the pulley and integral bearing. Once replaced, you turn the centre nut to release the tension and enable the belt to be slipped on.

It's worth sorting it out now before it goes completely.

I've had this problem.  I ignored the burning smell as the the belt started to fray and melt...but I got away with it as it disintegrated just as I got back to where I was staying but fortunately didn't cause any other damage.

Anybody got a part number for just the pulley?. Mine is a bit squeeky just lately especially on cold start first thing in the morning

thanks
