Just had to repalce the auxiliary belt for the second time on my 406
diesel. Started it up in work again the other day and it started making
some noises and on looking I noticed that the belt had moved over
towards the engine again and was rubbing against the engine.

The Haynes manual mentions something about a bolt in the middle of the
tensioner that you have to slacken to replace the belt but I can't see
any bolt there. It is possible that the Haynes manual has made an error
I suppose. Has anybody else had this problem and do you have any
pictures of the tensioner that I could look at to see if something is
missing.

Ta,

Is it just me or have the French made it deliberately awkward to work on
