heater matrix replacement

[pat]

Hi Guys,

I need some help. the heater matrix of my car is leaking and I don't now how to replace this. Do I have to remove the complete dashboard or is there an easier way? It's a 406 HDI 80 kW estate from 2002 (D9?) with ECC. The passenger side is getting wet with coolant, so i'm quit sure it is the heater matrix.

Appreciate your help.

Regards, Pat.

Hi there Pat, welcome

Apparently you can get to the heater matrix on yours by removing the glove box (I'd have to remove the steering column on mine )

Hi and welcome on in Pat,

I have no useful contributions on the matrix im afraid,

but Steve are you sure pat isnt in a left hooker too, he doesnt mention his location but he does say 80KW (like those bloody Europeans do ) not 90 or 110hp, just a thought,

so Pat where in the world are you buddy?

Thats'a very good point, errrr, Austria

Looks like you've got to take your steering column out Pat. It might be worth getting at it by removing the lower covers to see what's going on first.

Thank you for all your quick reply's and warm welcomes, what a good forum this is!!

Your right, I'm from the Netherlands (now you understand my poor English) and my 406 is a LHD. So if I understand previous reply's, I "just" have to take away the steering column to get access to the heater?

no as yours is left hand drive remove the glovebox to get to it

I couldn't see anything when I have my glovebox out, other than the fan. I think the matrix connectors are on the left too

Steve,

You could be right about the connections. On the bulkhead in the engine compartment the hoses to the heater are also a bit left from the middle.
Does this mean I can disconnect the hoses to and from the matrix from the left (without removing the steering column) and take it out from the right by removing the glovebox?

Regards, Pat.

That I don't know, the Haynes repair manual for the D8 says it always comes out from the left but the book for the D9 just says remove the glovebox without mentioning which side it's on Perhaps it would be worth taking the lower covers off and having a look.

From Passion406 (apologies for the rough Babelfish translation - do you speak French too?)

hello,
following an odor rather unpleasant to the setting of the heating, I must think of changing my heating radiator…
I think of making it at the same time as the belt of distri considering the water pump will pass there….

so did some among you already make, can you say to me if it is really necessary to deposit the steering column like it says the review or if that passes without that?

thank you!

hello yes it would be necessary deposited if not its will not pass

A .pdf (yuk) from www.coupe406.com - http://www.coupe406.com/documents/Tutor ... therme.pdf also in French but there's lots of pretty pictures.

Glad I`ve not got a left hand drive car....that job looks a pig!!

[steve_earwig]

It looks a lot less complicated than I'd have thought in the pdf.
