Having spent a "fun" weekend replacing my heater matrix (1999 Xantia HDi) I'm in no mood to ever do it again!
So what's the collective wisdom on why these fail and how to prevent it?
I have not yet investigated why my particular one failed...

Re: How to prevent xantia matrix failures?
It will almost certainly have failed at the join between the plastic top and the aluminum matrix.simoncanfer wrote:I have not yet investigated why my particular one failed...

My old ax diesel heater matrix failed exactly the same, at the joint where the plastic meets the core. Condition wise it looked as new when i removed it! I had changed the coolant regularly in that aswell, I guess its an age related thing.

Range Rover has Valeo Matrix and they fail like our Cits. They are a huge job to do . Someone was telling me of a shortcut with RR whereby a bit of the dash which is not seen can be cut out for accsess and then refitted. It makes it a whole lot simpler.

No, it wasn’t … never heard of that in the past.was the failure rate as bad
The heater core used to be all metal, and never was a cause of leaks.
The Xantia also has the hot water flowing through it all the time, while the older systems had taps like on the BX, where the hot water only flows when the heater is used for heating.
A buried matrix with plastic top is just cost cutting, incompetence, voodoo engineering, or deliberate mischief, if they’re capable of thinking that far.
My inlet tube leaked and the matrix got bypassed, but that’s only feasible because I’m in an area where you can live without heating if you don’t drive at night in winter.
