Is the spring loaded tensioner seized?a 32mm spanner on it will soon tell you!
If you don't have a 32mm,push down on the belt,and see if the tensioner moves at all.
If it is,it is not too hard to take off,but the(8mm?) hex headed bolt that goes through it,is usually effin tight!
On the other end of the spring bit is a 13mm bolt,undo that and with some wiggling the tensioner will come off,it may need a little gentle levering when it comes to refit time,tho.
If you get this far,take the tensioner and remove the big washer,it may have come off already,and the o ring,probably gone too,already.Use a socket or a drift and knock the middle out,I try not to twist it too much as all the corrosion acts like grinding paste and can leave the pulley running slightly off line,which makes belts jump off.
When it is apart,clean the corrosion off,trying not to miss any,off the pin part or the alloy housing . . . When done,grease it up,refit a new o ring at each end,under the big washers and refit it,tension the belt as in the link above and hopefully . . .job done and no rattle.
The trouble with these tensioners is that they are ptfe coated when new,no grease . . .which is fine until the o rings go then water gets in and corrosion starts . . . .
If you find that the pulley itself is the problem,these are available for about £21 from Mr auto(Iirc).
Oh and sorry,but I don't know how much a garage would charge . . . .
