Technical Coolant downpipe weld problems

[hymert]

I've got a 2006 registered motohome based on a Fiat 2800 Ducato. I've been told by the dealer that the downpipe from the engine coolant reservoir is likely to fracture at the point where it is bracketed on to the top of the engine. I can see a tiny rust spot at this point but there is no leakage. Has anyone else experienced similar problems. Thanks

Here is a section from my previous post on changing the the Timng Belt on the 2.8 JTD - https://www.fiatforum.com/ducato/218539-2-8-jtd-timing-belt-replacement.html which has relevance to this problem.

"I also removed the bracket bolted to the intake manifold behind the cover as it has some wiring harness retaining clips & two studs with nothing attached to either which hinders easy removal otherwise.
NB: On reinstallation of this bracket I bent the mounting lugs (& removed the studs) so that the two large plastic wiring loom clips could be used to support the coolant bypass pipe that crosses over from the thermostat housing to the front of the engine. This was done because I had asked the parts department at the local Fiat dealer what was the most common thing that went wrong with the 244 Ducato. Apparently out here, it is this pipe cracking from the vibration - which it certainly does, I was told it was $400!! to replace. Think I would use a rubber hose instead for that money."
Hope this elaborates on the problem
Cheers

Any idea from which date (approx) this was modified ?

TIA Dave.
