1. Buy these... https://www.skandix.de/en/spare-parts/interior-temperature/heater/heat-exchanger/clip-heat-exchanger-service-kit/1042870/
2. Fit them.
3. Find something else to worry about.
If you would rather try your second nearest VX dealer, then you need part number 93171800.

Shameless bump...
Terry, have you seen this?

Thanks, Doc, just seen it.
The man offering for sale the matrix and washers that I bought has given up and refunded my money. Seeing no way I could mend the matrix system, this morning I decided the car was probably a wreck. I therefore joined the matrix and pipes with the epoxy adhesive I used before on the thermostat. I will let you know how it turns out.

Yes, it is daft.

I agree.
I am not sure where I went wrong. Heater was giving out no heat, blocked matrix seemed likely cause. I could find no furum guide for the Omega, but Haynes made it sound simple enough, with his usual 'refitting is a reversal of removal'. I found refitting difficult
The car cannot be driven. What should I have done?
-
Finding the part number for the seals and clips took me five minutes. On top of the five minutes spent finding a working parts list. Neither of which was particularly arduous.
Granted, I could have done this when you first had the issue (as could anyone else :-X) but it is what it is... Not from being unhelpful but certainly from a lack of inclination.
If I were you, my next step would be to give the above part number to your nearest dealer and get them ordered. If they aren't prepared or cannot be bothered to, then order them via the link above.
Whether you need another matrix depends entirely on how much you may have buggered up the existing one.
Apologies if that's all a bit direct.

No need to apologise, all fair comment. The e-bay matrix came with washers and new clips, I could buy another easily enough. My problem was not managing to assemble it correctly. I still believe there must be a technique, a procedure, that I have not twigged. On the assembly line at Russelsheim they must pop these on in under a minute, with never a leak.
Using Loctite EA9492 was a desperate measure. It has not cured fully yet, it's colder than when I last used it. Having done so will make dissembly almost impossible.

Thank you, relieved to hear that. It begs the questions, how do they do it on the assembly line, and did Haynes find it so simple as to be unworthy of advice.

Never claimed to have on one of these, but removing the trim is generally the trickiest part...

On a Vectra?
No.
But I have struggled with that sort of clamp, and copious lubrication from the start was the solution. Limited access and rigid pipes are what make applying the force necessary to fit the parts together tricky.

Looks like I shall scrap it, Doc. Are you interested?

I have tried high temperture epoxy adhesive, one pipe is sealed, the other leaks. I may yet try other lash-up cures, but I am weary, and if DG, or anybody else, would like to try, I wish him luck.
My current dream is to saw through both pipes near the matrix, get good sight of the leak then repair it and rejoin the pipes with hose and hose clips.

Which is, surely, what henryd has just suggested re Marks post. Yes i know, "don't call me surely". ::)

This was suggested as a last resort previously in Terrys earlier topic about removing the Vectra footwell trim... :y

Having failed several times to seal the new matrix to its pipes with the washers and clamps supplied with the new matrix, I glued them together with Loctite EA9492. I was aware that if this failed to seal both joins I would have a problem. It failed to seal the upper join; I have a problem. Now I cannot remove the matrix.
My inclination is to scrap the car. Other options: saw through the pipes near the matrix, remove matrix, strive to seal the leak (upper pipe) with EA9492, reassemble with hose and hose clips. Any more?
Car is 2008 manual Vectra petrol 1.8 saloon, MOT expires October 14th, reg.is DN08BOV.
-
It looks like an awkward S.O.B.! :-\
-
You bought a cheap matrix, so sacrifice that:
cut it off so you can rescue the entire pipes without damaging their ends. A few minutes with a Dremel will work.
Order another matrix plus the genuine clamps and gaskets DG found.
Remove the gunge you applied; gentle heat from a small soldering torch will break down the epoxy, then you can scrape it off. finish with mild abrasives; soapy fine wet&dry and/or scotchbrite
Connect the two pipes with generic hose and clamps to return the car to service until your new parts arrive and you can face redoing the job.
You've not been defeated by much harder jobs, or bigger cockups. Why start now?
Good luck :y
-
Plumbing all reconnected. Heater still produces no heat. Bother. All that work for nothing. Pipes to heater are both hot.
-
Well done :y
Blend flap stuck? Have you had the heater panel out? Everything correctly reconnected in the engine bay?(iirc the Vectra doesn't have an hbv, so everything is within the heater box...)
Is there a reset procedure in the handbook? Possibly press and hold Recirc and Eco...
Be mindful that the facelift Vectra C has three different types of aircon: basic aircon (three dials- no auto setting and four switches)Life, Exclusive SRi/single zone climate control (three dials - auto setting on fan speed and four switches) Design, optional on SRi/dual zone climate control (five dials and four switches) Elite and V6 equipped cars.

Thanks Doc. Having removed the glove box I see a pink lever, but no fag packet black box. Mine seems to lever into a duct. Also it resists pulling off. Any thoughts?

There you see a pink lever on the right, but no fag packet size box. l
-
With engine running that pink lever moves when I turn the temperature knob from low to high, so I can imagine it turns a flap inside the vent to divert air flow.
-
If it's moving then that suggests that it's working :-\
If you pull the centre console trim below the glove box and disconnect the lever and move it manually... Any resistance on it? If yes, then you might be looking at another heater matrix, or at least removing that one to investigate the flap...
Personally, I would pop the trim back in and get it MoTd before spending any more time on it.
Once Motd, you can either tinker to your hearts content or swap it. Mot history suggests that it won't need much, if anything, but it's obviously worth more (financially and to you) with one :y

This car never gave out much heat on purchase ln June 2019. On July 2019 I see in a thread about a coolant leak I changed the thermostat housing with thermostat and commented that the heater worked better.
'Thanks to all for advice. On removing the thermostat it was clear from rusty lower screws and the appearance of the thermostat holder face that the thermostat gasket had been leaking (right again Doc), so I merely replaced the thermostat in holder. I drove the car 150 miles yesterday, no coolant loss, and now the heater works.'
Then followed more work on the coolant leak about the oil cooler, which I eventually cured, now the heater no longer works at all. Curiouser and curiouser.
-
Did you plumb it in the right way around?
How much sealant did you use?

I think it's plumbed the right way round, but I am not sure now. The two hoses to the pipes to the matix are interchangeable, and I could not see it mattered much.Does it?
I used no sealant.

I meant the oil cooler connections :-\

The coolant connections to the oil cooler had to be right, one end to the thermostat and the other to the water pump. I used new 'O' rings, possibly with a lick of grease, and the seal is still holding coolant.
-
Obviously something happened in the course of fixing the oil cooler.
Any plugs left in?

Fascinating theory, Doc. I thought the pipe from thermostat to water pump went via the 'T' connection to the oil cooler, then on to the water pump. There was a pipe from the water pump direct to the heater matrix, then it went to the thermostat, then either to the oil cooler or the radiator. Am I confused? I can see this might be my problem.
-
I have just checked; from a cold engine start, as coolant temperature reaches 190 after 9 minutes idling, both pipes to the heater are equally hot. I cannot imagine what went wrong when I changed the 'O' rings in the oil cooler section that could cause the failure of the heater.

this thread from the Vectra C forum concludes that if both pipes are hot then the matrix is not blocked, and the fault lies with the flaps inside. My pink lever certainly moves as I turn the temperature knob, engine running, but this has no effect on the heater output.
-
The hoses from the thermostat are connected the same way as on my other Vectra. Both pipes to the matrix get hot, which suggests the matrix gets hot too. The car has aircon fitted (no longer functioning). I suspect the flaps which mix the air from aircon and heater matrix are misbehaving. The recirculating air valve servo motor and linkage seem to be OK. I am out of my depth here.
Meanwhile all my three Astras have passed their MOT tests, so this wretched car is a spare. At a pinch concentrated winter screenwash, aerosol deicer and a pair of gloves, would make it useable for local runs.
