Hi, looking at replacing my aux tensioner/and belt today as it looks fairly old and cracking in places ..question is where is the tensioner and how do you access it , i have all the rads out and pipes from air con removed to make things easier 

[RobseyMV6]

15mm socket on aux tensioner nut and turn clock wise to lossen belt 
to replace tensioner pulley undo nut and take off, then replace and do up again.

top left pulley is tensioner for aux. 15mm spanner, rotate clockwise to move it to slanken belt for removal

I can see the pulley/tensioner wheel , so is the nut adjuster located at the side ...looks like very awkward access ?

Its spring loaded, so no 'adjustment', as fully automatic. 15mm clockwise pushes against spring, allowing belt removal

in the middle of the pulley, the whole pulley moves.

yes, put your 15mm spanner on it & turn clockwise, as if you tightening it up, the pulley wheel will move to the right allowing you to remove the belt.

Got it ....Had a pully shatter on my last 3.0 and the belt wrapped itself in some most unusual places , left me stranded on the M1  someone i knew replaced the belt but couldnt remember how he slackened the belt off .

Thanks all

when fitting the new belt, put over the tensioner pulley 1st, then slide it over the waterpump pulley last as its smooth & it will slide over easier.

Will do  while looking at the state of the aux belt im wondering when the cambelt was last done I know it was done at 80000 but the car has done 40000 more since . Does the plenum have to come off to remove the cambelt plastic cover ?

belt & tensioners need replacing then, change waterpump while you at it.
plenum comes off, yes.

Might as well while its all apart , i was thinking when the new rad comes tomorrow just to put it all back together but the cambelt condition would be on my mind ... will enquire how much a kit and pump is and sort it out

have a look at www.vauxhallworldparts.com
they sometimes have a good deal on gates kits.

This one on ebay i found   http://www.ebay.co.uk/itm/Timing-Cam-Belt-Kit-VAUXHALL-/300640813274?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3AOmega&hash=item45ff96c0da

Not a bad price but ill ask in the local car acc shop if they can do any cheaper ...think its about £23 for a water pump
