- How to remove the heater matrix in a Peugeot 406, without having to remove the whole dash.
The heater matrix uses the engines coolant to heat up the interior of the car, when the coolant is warm it passes through the heater matrix, essentially a small radiator, the blower passes air through the heater matrix which then leaves the air vents as warm air.
Unfortunately in some cases the heater matrix can leak or become blocked, if it leaks then you will notice a loss of engine coolant, soggy carpets, misting windows, and a smell of coolant in the cabin. In this case its important that you change the heater matrix as soon as possible to avoid damage to the engine by overheating.
In some cars you need to remove the whole dash, but here i show that it is not necessary with the 406. Its not the easiest job due to limited access for some of the fixings, but it is possible with ordinary tools, one thing i would recommend is torx allen keys which would avoid the need to drill into the dash.
I dont flush out the coolant before doing this job because the car used here is for the scrapyard, if your car is a good car then drain the coolant, and have a container ready to catch any coolant when removing the pipes to the heater matrix.
When reinstalling the heater matrix use new O ring seals, there would be no point in going to all this effort to have another leak because of something as simple as O rings.
I have no idea why a heater matrix would develop a leak, perhaps if your pollen filter is damaged and letting in particles that may puncture it, or if you don't change you coolant frequently then it might start to corrode the matrix from the inside out.

Great videos, have a wet carpet at my driver seat, and it tastes like coolant so this was informative, guess i have to change the heater matrix. Have a leftsteered car but shouldnt be that different. Really good videos!!
Hi did you fixed your leak?İs it the same at a lefthanded peugeot 406 ?
very help full video thanks a lot mate 🙌🙌🙌🙌
+Zafar Iqbal Glad to help thanks for the comment
thank you very help full .
Thanks for the interesting video, now I understand what the heater matrix is.
Anyone who is changing coolant ect please please clean it all up. Cats and Dogs are attracted to it (due to its sweet smell amd taste) and the antifreeze in coolant is highly toxic leading to death very quickly. Ethylene glycol has a very narrow margin of safety - which means only a tiny amount can result in severe poisoning. As little as one eighth of a teaspoon per pound of body weight in a cat of undiluted antifreeze can result in fatality.
Thanks for the video..
Thanks for the important safety note. As i have a very hyperactive collie pup i find the best thing to do with antifreeze is when draining any is to keep the pup away until it is all cleared away.
this video is of the peugeot partner van of 2009??? because i have a leackage from under the dash
thanks
Hey! Does this matrix have anything to do with the AC syste?
I've changed the compressor, ac radiator (in front of the main radiator), changed 1 pipe and made sure all seals are fine. It still leaks refrigerant somewhere?!! Could it be from this one little radiator under the dashboard? Or it holds only engine coolant?
Please advice.
Cheers!
very impressive and informative! So does this technique work on all older peugeots (306, 206 etc) or just the 406?
Im not sure about the other peugeots, they might possibly use the same heater matrix unit but weather or not the dash sits in the way i am not sure.
hello and thank you for such good videos. my question is related to peugeot 106 XSI heater radiator removal. can i do it without removing dashboard and how please give me a tip

Nice video, very informative.
I assume its a similar job on a 307?
Hi, thanks for the comment
Not too sure about the 307 i have never actually changed the heater matrix on one
nice job i try and hope
It isnt too bad a job on these, some of the other PSA cars you need to remove the dash to get access to the heater matrix.
Hi,very good job 👍İs it the same with a lefthanded peugeot 406 ?
I'm not too sure, i think the heater matrix is still installed the same way around so the steering column may need moved.
blonde girl takes her car to a mechanic when her car starts to run rough. Nothing to worry about love "says the mechanic" just shit in the air filter. great says the blonde, how often do i have to do that?
would this work for a citroen xsara?
+Jeremy small My mum has a Xsara and i would need to check i dont quite know, at the moment i doubt the xsara is the same but they might have designed the matrix so it can come out without removing the dash
+peugeotCitroen2CV oh okay thanks for getting back to me, i was asking because im goi g to have a go at it next week because my heating is cold lol andthats my last solution and as we are going into the winter its not cool having a cold car lol
Does the car have 2 of those heater matrix or just one?
Just the one
Great video :) does it work on a 306 st.car ?
To be honest i dont know, i have never done this on a 306, but a mate has left one of this week ill take a look and see, although i know its not possible on the xsara hatch i have and it shares most of its bits with the 306.
Doesn’t anyone know to remove the evaporator core on Nissan qashqai 1.5 diesel
E manuals online, download a manual for it should show the process to remove the evaporator. The quashqai is not a car i have worked on a great deal.
what size is the O ring
I cant say that i know myself what the seal size is as i never took any measurements at this time
However i have looked on peugeot servicebox
The part number is 6462 40
This i think should be what you need: www.ebay.co.uk/itm/646240-6462-40-Citroen-Peugeot-SEAL-/222454626193
20x3 mm
Hi / u r the best /what about Citroen Xsara! can you

May also be worth trying the same but for vw sharan and seat alhambra.
