That's more of a squeak than a squeal.  A slipping fanbelt is quite a distinctive squeal, a shriek almost, not like that and will happen particularly when you rev it.  If that is the case spraying some anti slip on it will stop the noise but carry a spare belt as the belt will go soon.   However your squeak sounds like a bearing noise.

Obviously it is difficult to tell where it is coming from in a video but just in case put a stethoscope on the timing belt cover (or briefly run without the aux belt as suggested) and make sure it is not ththe timing belt, the most expensive problem if not fixed.  My timing belt made a lot of noise when it was going.  Not like that squeak though as I recall.

95% thats tensioner pulley bearing mate ;)

As Kevin says, try it with belt off - but only for a very short while (that belt drives waterpump)
If its quiet then try removing and regreasing pulley.  I suspect though you will need a replacement.

I thought it was the tensioner to be honest. How hard is it to do the tensioner?

Get a new pulley only, not complete tensioner (~£25 on TC from memory)

10 minute job, drop aux belt off, undo 15mm bolt through pulley and remove pulley, fit new tighten bolt and refit belt - job done :y

Could be many things that's what's so annoying  :-\

Pulled the tensioner off today it was bone dry all greased up now and put a little more in the new pulley will go for a run again later.. Easier to take air filter box out to check/remove the tensioner  :y 

Symes comment made me wish i'd checked mine also seen as i had pretty much everything off  :'( ;D

No need to remove air filter box to remove tensioner assembly ???

If pulley bearing dry just remove pulley - 1 bolt (15mm) - off in minutes ::)

Aye, If you want to get the 2 large long bolts out holding the tensioner with a little more ease yes IMO :y

Hmmm interesting thought on the alternator bearing,never heard one squeak before...a grinding yeah but not a squeak.

Im sure Irmscher Jim will have a spare alternator we could try :y
