Simon's new Xantia V6 and Leaf blog

Bugger! Now that is a large spanner in the works!

So it calls up the same intermediate pipe and the same rear box, yet a different clamp. Got to love Citroen

Good grief! At least I will have both size clamps to cover all bases!

This is like the handbrake cable saga (trying to identify the correct hand brake cables for a V6) all over again...

That explains why I have a 74.5mm clamp in my collection that never seemed to fit my Xantia...

Kept my interest ... riveting discussion for a wet Thursday afternoon

What I really notice is the exhaust is NFP. Thank goodness for the good old Poles for still turning them out even if they have crooked tail pipes...

Just picked up the two types of clamp and while they're the same design the size difference is obvious:



Anyone want to place bets on which one turns out to be the correct one ?

Not keen on that design of clamp as they're hard to reuse, but hopefully it won't be back off again in a long time...

I would pack the threads with plenty of copper slip grease. I might even coat them in the same.

The correct one, or the one that fits? Especially as we don't (yet) know the flange size of the back box.

Just looking at the size of the clamps in my hand - I don't think the large one is the correct size for any V6 back box - even a S2. There's no way the back box flange is as big as the one on the tail of the cat.

So I reckon we'll find the listing on service citroen saying that the back box uses the larger clamp on S2 is in fact wrong and that all of them use the smaller clamp in that location. (And the large one on the cat tail)

Simon,

If the big one isn't the one you need I'll buy it off you then as I need a large one to secure the cat on the XM.

Sure, no problem David. If I don't use it its yours. Does the part number match for the XM though ?

I only really got it in case the whole centre section has to be disconnected from the cat to work on the exhaust more easily - I'm hoping that won't be necessary! That was before all the confusion about whether the larger clamp was in fact needed for the back box but I reckon it's not unless my memory of the other V6's exhaust system is playing tricks on me...

So i win the prize then

I'll PM you my details so's you can get it in the post tomorrow ...

You don't win anything until the job is completed!

No problem with a pair of these:

[CitroJim]

Ha! I often wondered if there was a special tool for those clips

I made one using a set of extensions on the end of circlip pliers...

[RichardW]

Bought them when I did the turbo on the Picasso - there is one of those clamps at the top and bottom of the DPF - which has to be removed to get at the turbo (and there is not enough room at the top for any other type of clamp). They've got a clip on the side so you can expand the clamp, and leave it expanded whilst you pop it on the pipe, then line the joint up, and drop it over. No bother. Trouble is, you still have to get the joint properly aligned, otherwise you have to take the DPF heat shield off again - which involves taking the radiator out again.... Still, rad had to come out anyway to change the AC condenser so all was not lost completely
