Jim

I dont know what im going to do for pre bedtime reading when you have finnished this project

And will the V6 be prowling the streets by the end of the month then?? or are there other things, oil pump strainer, cam belt/tensioners etc that you want to do first?

Don't worry Dean, There'll be plenty of bed-time reading in this blog for a long time yet

The gearbox is only one item requiring attention.

After that, there's the following adventures:

Cambelt/waterpump;
Heater Matrix;
Hydraulic leak from the rear hydractive block;
Front Brakes;
Blower running at hurricane speed.

Plus, no doubt, other things not yet revealed

This blog will go on and on....

Well at least the engine is out so the cambelt should be a pleasant experiance for you, although maybe not on the wallet.
Havent worked on a Xantia before but i have heard of grown men weeping at the thought of heater matrix replacement in them so i wish you all the best there, everything else sound like a good bit of tinkering, i take it you will just change out the Hydractive block? or rebuild?

I live to tell the tale of a heater matrix Dean

I assisted in the replacement of the one in my 2.1TD and was coached by a real vetaran matrix replacer. But yes, they are a nightmare of the highest order and by far the worst job on a Xantia

11 hours of solid work.

The electrovalve is leaking on the hydractive block when in soft mode. The usual problem of the alloy of the valve body corroding. the block itself is Ok so a new valve should crack the problem. The downside is they're eyewateringly expensive new. Luckily I have a good one in my stash but it needs new O rings and they're not available seaparately. I'll be having a chat with martin at Pleiades about suitable O ring material for that.

Cambelt should be good, except for the cost, I've been very kindly loaned the kit of special tools for the job

Access is currently brilliant

Everything else, relatively, is a nice gentle walk in the park...

I've gone past the stage of just fixing the problems on this car, it's now officially a restoration project...

I have always found this strange, you can get a refurb kit for an FDV (although cit list them as balljoint kits

) but you cant get any height corrector seals / parts individually so you can re build some things but not others and it seems the MK2 XM/ Xant hydractive blocks are the same story:? .

Just to rub it in, the Xm matrix took me. ooh, a whole hour to change last year!, i know i know, poor me

Hi jim,
on my car, when cold, between engine and box make a strange noise. the noise become lower and disapear in a few minutes, even in driving or idleing. And if I took it from P to R, the noise lower suddenly.
first time of the problem, the noise not too loud but later is becoming louder and louder.
what is that??where is the noise come from?

Welcome to the Forum bl4ck clio

What type of 'box is it on your car? Knowing that, I'll be able to give some better thoughts on it but generally, it's likely to be caused by much the same as on the 4HP20.

I take it they are easier to get at!

Sounds like the noise is engine speed related, IF it is the box the only things that turn at engine speed when stationary are the Torque converter and the oil pump....................wonder if the torque converter mounting bolts are loose???? but that wouldnt stop as the engine heated up though.

Some take the steering column out to ovoid damaging the fins on the corners of the matrix but its not worth it imo, take a few screws out, a couple of pipes, catch the deluge of coolant, pull and the old matrix is in your hand. It does sound much easier than 11 hrs hard graft, i would hate to see a stealer bill for that job

If only the Xantia had been designed like that!

my dealer workshop say, the noise from the plate between torque conveeter and flywheel. it has triangle face. It maybe have crack (near the bolt specificly).
Isn't it true?

Deanxm · Post by **Deanxm** » 10 Apr 2009, 09:45

It is possible yes, it could have cracked due to stress, the torque converter is bolted to the flywheel, usually by only 3 bolts and if the flywheel has cracked badly and one of the torque converter bolts have let go it would make a nasty noise.

Hope its cheap for you

That plate is called the flex plate, and problems can happen with them here's some information on them.
