Hello guys, after I searched the net for days in vain for a description, how to change the heat exchanger with the Peugeot 406, Bj 05/1999, petrol, I now ask here in the forum for your help Have found here already a post by DiNERO, where he writes that this is not so complicated, and then wrote it on, but up to now I have no answer. However, I have to work slowly, since the coolant smell becomes quite annoying (apart from that This morning I went to it and removed a few panels and the center console. I think that I found at least the supply lines to the WT, but I still don’t know how to get to the thing best. What’s also surprising is that I could not detect moisture near the supposed WT. Are there other reasons for coolant odor in the interior? The smell kicks away. always on when the vehicle is warm. Cooling water level is OK, engine oil a little bit. Please help me, I’m quite frustrated!!!!!
