Just about to do this (raining today) and have a quick question, I assume the bolt is right hand thread ?
Just checking before using an air impact wrench. Should be right hand thread as the pulley has a woodruff key so shouldn't turn anyway, still you never know, wouldn't be the first time I have tried to remove a bolt the wrong way, usually resulting in snapping them.
Fitting one of the new pulleys from Corteco which have a solid looking rubber face, without the slots.
I wasn't sure it was right and rang them, they told me these are better / safer as they are concentric rubber rings rather than rubber discs. We shall see.

Re: Xantia engine pulley change
Yes, RH thread. Put it in 4th gear and apply the handbrake hard, should be enough to hold it if you are using an impact gun. 22mm socket required....

Re: Xantia engine pulley change
Just another question on this, I had to give up as I couldn't release the lower adjuster so didn't want to fit a new belt and not be able to adjust it.
This is the lower adjuster not the spring loaded top one (Xantia HDI 90).
Question is how hard should I have to turn to release it and will an air powered impact driver help ?
The adjuster uses a hex key, not a square one as most seem to be, so my plan was to use a hex bar I have that fits it then use ai impact driver on that.
I have only used an impact driver (air powered) a couple of times, would this be a better way to remove the adjuster as it should 'ease it out' rather than seeing the twisting of the allen key as at present.
Breaking this would be a real pain.

Re: Xantia engine pulley change
Are you talking the Aux Belt, eccentric pully?? They are an 8mm ALLEN head bolt...
The upper spring loaded tensioner uses a LEFT handed thread on the bolt. Remove the ECU box (two 10mm bolts are removing the ECU out the box) you can get at it easyer.. Use a 15mm YES 15mm spanner on the bolt head to left the tension and release the belt...
The eccentric again is RH thread. ONLY the upper spring tenionser is a LH thread for obvious reasons..

Re: Xantia engine pulley change
Sorry for posting this then wandering off, but back now.
Yes it is the eccentric pulley, at the bottom of the engine. Good to know which way to turn it
I am a bit of a wimp when it comes to putting massive pressure on bolts etc, I have sheared too many with dire / expensive consequences.
I was hoping using an air impact wrench would loosen it with a lower risk of shearing.
I really want to do stuff myself, but if there is a risk of shearing the bolt I would rather it was in a garage where they could fix it. Replacing the crank pulley ant timing belt should be a simple procedure, just this tensioner pulley that is worrying me.
