Hi all.
Got a squeaky pulley.
Sprayed WD40 and found out, as you look at the engine from the front, it's the big pulley top right hand corner.
Can some one please tell me if this is just a pulley for the belt or is it a part the belt is driving.
hope you can help.

The belt tensioner usually makes the noise.
The two top pulleys are tensioner and pas pump
-
Top right from front of engine is Power Steering Pump pulley, which is indeed driven by the aux belt.
-
Low fluid will make a noise too
-
Belts can squeak too. I had a mysterious aux belt squeak that would come and go; I eventually cured it by replacing the belt.

Someone posted about a squeak from their car and it turned out to be the tensioner. so as mine was making the same noise I changed it only to find out it was the cambelt tensioner. and I'm still waiting for my new cambelt kit to turn up from a company I ordered it from on Wednesday and paid the extra postage to make sure it got here in double quick time.

Good job you took notice of that. 3.2 tensioning and alignment is slightly different from doing a 2.5 as per the dvd. Lower idler has no adjustment, or at least it didn't on mine.

How did you determine the squeak was the cam belt tensioner? It's easy to establish it's the aux belt or its pulleys, you just release the tension on the belt with engine running and see if the squeak stops.
I have suffered aux belt pulley failures, but they do it silently as the bearing seizes, then the belt slips, breaks, lights come on, power steering stiffens etc. If there is a continuous squeal varying with engine speed, it's probably the aux belt squealing as it passes through the pulleys. If the above seems too dangerous, spray some WD40 on the belt and that should stop the squeal.

I just assumed that as I've replaced the belt/tensioner as well as the alternator that it should not be any of them making the noise as it disappears within a few minutes.

If the OP found that spraying the belt with WD40 stopped the squeak, it was definitely the belt, not the tensioner. WD40 lubricates the belt running through the V pulley, not the tensioner bearing. Any belt running through a V shaped pulley is liable to squeak, cure is replacement. I had to replace 2 new Vx cam belts because they squeaked. JamesV6CDX suffered similarly; after considerable mileage his got quieter.

Thank you all for all the replies :y
