I'm assuming that since people report frayed tatty belts with teeth missing or rounded coming off still in one piece, that if your belt looks in good condition it should be reasonably safe from snapping, but I don't really know if that is a safe assumption. Anyone?

When I did the belt on my BX16V earlier this year, it looked OK from the outside but I had a gut feeling about it.
When it was removed, I inspected it closely & found that where it is joined, it has a kind of stitching. This stritching was in fact worn down & showing signs of splitting on the joint. This was totally obscured from view when in position, so as I intended replacing the belt anyway, it was situation as planned. However if it was just an inspection, I would have definitely opted to replace it; ya kinda "gulp" heavily when you find that kind of thing.[:0][:0]
Based on this experience, I wouldn't even think of not replacing the belt unless I knew for sure who had fitted it & when.
FWIW, my belt was supposedly fitted about 25,000 klms prior to my inspection. I checked it due to having found other jobs done by a so-called "specialist" that in my opinion weren't up to scratch.

It isn't really safe! A belt can look sound from the smooth side, and yet when it's turned over and flexed in reverse, the base of the teeth can be seen to be split.

I fear that Anders is being a little pessimistic. Any non citroen backstreet garage can do this cheaply if you really cannot do it yourself. Personally, knowing that GSF sell spheres at about a third of Main dealer prices, I'd have done the spheres myself, (Doddle, really), and have the garage do the belt instead.

Tom -
I think it's a bit far out - to interprete my submission as pessimistic [;)]
I see no reason why a DIY'er - or an independent garage - should NOT do this job perfectly.
I just tried to point out - that replacing the cambelt IS in fact fiddling with the most fatal part of the engine. Needs some good thoughts before you start off on the job.
It's not just an oilchange job - if you get my point [8D]

On a diesel, maybe, I'd have a go.
But a petrol? Guessing the tension?
[I don't think Anders is being pessimistic, just realistic - here's the proof: is there anyone on this forum that has done this job on a petrol Xantia...anyone?? Apparently not. And now we know why. Thanks Anders]

The reason nobody on here seems to have done a petrol is because....dare I say it....the smart money goes on diesels.....oops there I said it.
Not wishing to be rude or disrespectful but the real hands on crowd are more likely to have a diesel than a petrol, why, maybe they know something the petrol crowd don't, what a spanner is for instance[:D].
Examle, a workmate would like a diesel but allways end up with a petrol because diesel's are too complicated, this yooth doesn't know one end of a car from the other yet he knows how complicated a diesel is, figure that out.
The fact is they are much simpler in operation, though they have now been spoiled by all the electronic shyte to the extent that they are now about as complicated and as reliable as a petrol engine, and look at them bloody things, reving here reving there oxygen this lambda that, spit fart pop, who'd have one[:D].

All true Dave.

I hate to disagree Dave; However, I’d choose a petrol engine every time.
I’m a time-served Engineer (Mechanical Automotive) and have enough experience to know that Diesel doesn’t get grease stains off your trousers. Neither does it run your lawn mower when you’ve been too bone idle to pop down the local tax-collectors for a gallon of revenue-juice and the missus is watching, gimlet-eyed to see if you’re skiving (again).
There’s a pleasure to be had from setting up a twin-choke carb so that it runs sweetly throughout the rev range and a perverse sense of achievement to be obtained from getting the timing spot-on with an elderly car so that it runs as the good Lord intended, despite the elixir of valve life having been removed from its fuel. Calibrating and phasing a Diesel pump??? Er, where's the romance - the <b>SEXINESS</b> in <b>THAT</b>???? [:D][:D][:D]
I’ll sing along to an ‘Essence’ V6 on maxi chat – but a Diesel? Who asked for the percussion section anyway???? [;)] When I bury my foot in the carpet want a surge of raw power – not an asthmatic grunt of HGV wannabe lust!!!!!! [:p][:p][:p]
(All in good humour, Sir! ;-) )

Hehehe and all taken in good humour don't worry.
But now the serious reason for owning a diesel, and my personal number one out of the three, the other two being economy and reliability.
A few years ago on a wet Nottinghamshire road there was a family of three riding in a car, it wasn't new in fact it was quite old, anyhow it was being driven by the mother with her husband in the passenger seat and child in the back.
They came to a bend and unfortunately were going too fast for the conditions and they strayed onto the opposit carriageway and into the path of a lorry, the impact though not that severe was enough to tare the fuel tank loose, it being full of petrol ignited at slightest provocation and the car was instantly engulfed in flames, the husband and child got out with no serious injuries, the mother was trapped by the pedals, they and the lorry driver could not get near to do anything because of the flames and heat, she burned to death in front of them.
If that car had a diesel engine in it a fire would have been unlikely in those circumstances, diesel being a much more dosile fuel than petrol, any fire if it happened would have been local to the source of ignition, fuel scattering itself on the road surface under the car would not have burned.
I could tell you of another accident where five kids would have walked away from a bit of dodgy driving, but because of the petrol engine they died.
So you are welcome to sail along in your V sixes or whatever, just make sure you keep it between the ditches and that you can avoid the plethora of assholes that make motoring so dangerous, becuase if you can't that fifteen gallons of liquid explosive under the back seat might just spoil your day[:(].
I have a car to get me around, to work and back and to the shops, I don't have one for reasons of sexiness, exhilaration or whatever, I don't pamper it I use it, I don't spend money on kitting it out with fury dice, silly lights, stripes and the like, I will spend any amount in maintaining it to a High standard of safety to afford my family and anyone who rides in it the best chance if the worst should happen, and if it does I'm glad it runs on diesel wether it sounds like a bag of spanners, or smells like a lorry[:)].

Petrol engines are great in fast cars but citroens are usually bought for comfort and utility. My XUD9 is the quietest diesel I have ever come across. The ignition doesn't get damp and the engine runs on a tiny amount of fuel. Mid range torque is strong and after years of rubbishing Dr Diesel's evil invention, I have to admit that I am almost convinced. Mind you my engine has done 150,000 miles so I suppose it is thoroughly knackered compared to a petrol engine of the same age ;-)
