Keep an eye on the Engine / Coolant Temp when running with no Aux Belt, they warm up rather quickly. 

[The Sheriff]

Just got round to having a listen. That's a bearing of some sort, sounds as dry as a nuns fanny.

You've done some strange things in your life matey.   

[mka306]

Sounds like payday will be shelling out for a cambelt, kit & water pump just to be on the safe side, can't risk losing the big lump for something that I can sort out especially now I have the DVD guide from OOF on changing the belt kit and w/p

[deviator]

Did you take the aux belt off first? It could just be the tensioner on that, unlikely but you'll be miffed to do a cambelt and still get the same noise.

As deviator say just says & I said yesterday, run the engine without the aux belt for a short while, if the sound disappears then it's aux belt related ie alternator, tensioner roller etc

Being honest, if you're confusing a fan/aux belt with timing belt I'd ask someone else to look for you

I realise which one it is now and I will check but to be honest it will be good to change the belt, kit and water pump just for piece of mind.

It's up to you, but it's not a job for the faint hearted.

That's why I bought the DVD on how to do it, if I can do an oil cooler change I should be able to manage a cambelt change.

the consequences are somewhat different though ......  Make sure you beg or borrow a proper cam locking kit 

Jumping straight onto a possible cam belt tensioner/idler bearing is jumping the gun a bit. Just slip the aux belt off the tensioner & run the engine before you think along the lines of cam belt

I totally agree with you and I do intend on taking the aux belt off and checking if the sound is gone or not, but my point is would it still not be better to get it changed so then I know the belt won't go on me anytime soon and the water pump will be good?

[Andy B]

Don't you have any history of when it was last changed?  I'd leave the water pump  .... if it ain't broke ...... don't fix it  assuming it's a GM pump, which is better .... a second hand OE pump or a new pattern pump?

The Water Pump runs off the Aux Belt, nothing to do with the Cam Belt Change, whip the Aux Belt off, as said before, my money is on a noisy water pump bearing.

OK I will do it today and report back.

My opinion as well.   If you remove the aux belt , you will find out instantly if the problem is related to those components that the belt runs.   

Would advise that you make a sketch of the aux belt route though before removing , to assist refitting of it

Bottom line is though  . . DON'T  run the engine without the aux belt more than a couple of minutes
