WES180 Posted November 29, 2016 Share Posted November 29, 2016 Hi. The gutter rails have been mentioned before for possible leaking points along with rear lights and hinge mounting points. My 2012 Focus was actually leaking through one of the rear quarter body air vents located behind the rear bumper. Its easier to sit a trickling hose pipe on the roof and then wait for the water to start coming in so you can trace it back. My wifes Grande Punto had a leak due to one of the body panel seam seals perishing! It really is time for a bit of investigation work im afraid rather than guessing.

I had water leaking into my boot, and using a watering can, tracked it to the gutter. In warm, dry weather (ha!, might be some time from now!), I firmly shoved a generous amount of silicone sealant up under the gutter, in between gutter & roof. It seems to have stopped it. I Just have water coming in the front now. I have not managed to track that down yet. It may be the windscreen. Bah. 1 Quote Link to comment Share on other sites More sharing options...

If it is then a good smearing of grease on the gasket will create a seal. I always do that on my cars as it cured a leak in the past for me. You should be able to see on the gasket if water has been getting past it as there will be a slightly dirty residue on it where its been leaking in. I wouldnt use silicone as you need to be able to remove the light unit in future to change bulbs, grease doesnt set so it will not stick the light and car body together. 1 Quote Link to comment Share on other sites More sharing options...

When light, if all is not frozen solid, I will try to get one. I just re-read wot I wrote, and didn't mean gutter, I meant roof rack rail. It was late! The C-max may be different in design there. I checked the rear light cluster thoroughly first, it did not seem to be that on mine, but it is a weak spot. Quote Link to comment Share on other sites More sharing options...

I just pushed the nozzle in as far as it would go (where the screwdriver is), and squirted plenty of silicone in there. It seems to have done the job. It does not look like the area inside that tailgate has been washed recently, or indeed, ever ! Quote Link to comment Share on other sites More sharing options...
