darkshadow Posted January 1, 2021 Author Share Posted January 1, 2021 thanks for reply. are the vents allways open?. if so it would explain why the boot is very noisy. lot of road noise. i will be putting some sound deadening in when the water leak is sorted. i have also heard that the roof rack fitting , the black strip on roof could let in water. any idea how this is fitted?, Quote Link to comment Share on other sites More sharing options...
Swearwolf Posted January 1, 2021 Share Posted January 1, 2021 its almost always the spoiler, take off, silicone round the mounts and reattach failing that do the same for the tail lights Quote Link to comment Share on other sites More sharing options...
pragmatix Posted January 2, 2021 Share Posted January 2, 2021 The leaky vents is normally a Focus problem not Cmax one, certainly on mine the layout is different as far as I can see. Quote Link to comment Share on other sites More sharing options...
darkshadow Posted January 3, 2021 Author Share Posted January 3, 2021 i have added a image of the area in the c max album page. the area where the water is pooling is where the screwdriver handle is. there is no sign of water running to this area making a mark in the talc powder. if i cover the area , water will pool under .

Gronez Posted January 22, 2023 Share Posted January 22, 2023 Did you ever get to the bottom of this? Mine is pooling water in the exact same place and I’m struggling to find how it’s getting in. Thanks Mike Quote Link to comment Share on other sites More sharing options...
CharlesMax Posted January 27, 2023 Share Posted January 27, 2023 Hi! In my 2006 cmax the water enters through a gap between the bumper and the rear wings. The bumper is about 5mm lowered, I imagine because of a blow it received. The water appeared under the side trims of the boot, and turned the spare wheel space into a swimming pool. The check I did: I removed the side and bottom trims of the boot lid, and focused a garden hose against the slot between the wing and the bumper. On both sides (one more than the other) a lot of water entered (green arrow) By now I haven't time to disasamble the bumper, I have stuck duct tape covering the gap from the wheel arch to the boot lid, and the issue has been solved (in about two months all is completely dry) Quote Link to comment Share on other sites More sharing options...
CharlesMax Posted March 25 Share Posted March 25 Hello! After a while, I have solved it. Under the bumper, there is a vent, one on each side. In my case, one of them has a small crack, but the other one does not. And I have water coming in from both sides. My conclusion is: a relatively small bump slightly wrinkles the metal contour where the vent rubber rests, and the vent loses its watertightness. On the inside, there is an insulator that absorbs small rainwater leaks, which means that the water inside the boot is not visible in the absence of heavy rain. My solution has been to seal both sides with silicone. To remove the bumper, underneath there are two small plastic screws, one hidden under each of the reflectors, and a nut hidden under the wheel arch. To access it, simply remove the last two screws from the wheel arch and turn the cladding a little.

CharlesMax Posted May 4 Share Posted May 4 Hi guys... this has been a failure. Water is still coming in. I have disassembled these vents and sealed them with plastic caps that I have cut to size, sealed them with silicone... and water is still coming in. I'm quite lost with this...

Bol Posted May 5 Share Posted May 5 If nothing works. Attach two layers of aerostop on this part. Did this to fiesta and it worked. It isn't sure it shall be a solution for every case. 1 Quote Link to comment Share on other sites More sharing options...
