I am planning to change the cambelt, tensioner and alternator belt this weekend
I haven't changed a cambelt since I last did them on my GSA a while back....... this was dead easy once all the panels were off
Thanks,

Take careful note of the routing of the Auxillary belt as it's nothing like any other engine. If you do loose how it goes, I have a diagram...The cambelt really is a lovely job on the Activa, bar for two things. NEVER use the crank pulley as a timing reference as the hole is on the outer of the dual mass part and it always slips. You must get hold of a solid pulley from a lesser XU engine for this and I use one from a 205GTi engine.
Secondly, it has a manually adjusted eccentric tensioner and you have to be careful in setting the tension on it.
That aside, the job itself is this: Remove the crank pulley by undoing the central bolt and normally it's not too tight as it should only be done up to 88 ft. lbs.
Remove the timing belt covers. One bolt is a bit tight for access but you don't need to touch the engine mount.
Time the engine and pin the cam in the timing hole and crank in it's timing slot using the pulley you obtained for that job.
Loosen the eccentric tensioner and slip off the old belt.
Replace the water pump as a matter of course. Check the condition of the tensioner and jockey wheel. If they run smoothly there is no need to replace them.
Replace the belt and tension so that the longest run of the belt can be twisted between thumb and finger an easyish 90 degrees. Don't over tension as the engine expands as it gets to operating temperature and if the initial (cold) tension is too much it can be over-tensioned when hot.
Check the timing carefully and then remove the locking pins and spin the engine over a good four or five full revolutions with the crank pulley in place. Recheck timing and tension.
If you want, leave the covers off and run the engine up to full temperature (be careful of any fuel lines that may chafe on the exposed cam sprocket) and recheck tension whilst the engine is hot. On the longest run of the belt, you should be able to just twist 90 degrees.
If the belt whines then it's too tight.
Job done!
After reading up on changing a rear ABS sensor for my Xantia a few months back, I found that in the latest BoL ('93 - '01) that you need to jack up and secure the front of the car on axle stands to get at the rear ABS sensor...hmmwainy wrote: More useful than a normal Haynes manual too....... My favourite piece of bad advice from a Haynes manual is that you need to take the dashboard out on a GSA to change the left hand wiper pivot, when actually all you have to do is take a speaker out! Come to think of it, I'm sure the Xantia manual tells you to take the dashboard out to change the heater controls.
Think there must be someone at Haynes with a dashboard fetish.
