addiosamigo Posted December 25, 2018 Share Posted December 25, 2018 I have noticed that I have a leak somewhere as there is water in the passenger footwell (left hand side). I know this is common issue in the MK2, but can't see a pollen filter anywhere when I open the bonnet. What I have noticed is that the windscreen surround has come away at the top of the screen, it's plastic not rubber so not easily going back in place. Could I glue it? If so what would I use? I've highlighted the problem area below.

Gymfocused Posted December 25, 2018 Share Posted December 25, 2018 Could be the heater matrix. The pollen filter is inside, under the dash. You can access it from the passenger footwell. 1 Quote Link to comment Share on other sites More sharing options...

If water is blowing in under the roof, it can track along the roof and down the A-pillar (at the side of the windscreen) and into the footwell. I have had this, from a hole in the roof made by a previous owner. Removing the A pillar trim inside the car might help identify if that is the route, eg by putting some paper in it. Pulling that pillar off often damages the fixings a bit, but it will still hold in place after. If it is from the heater, then a smell of antifreeze should be detectable. I would try using a decent silicone sealant to fix the surround to the screen. It is flexible, and removable if it proves to be too weak. 1 Quote Link to comment Share on other sites More sharing options...

Sort of like a glue? If so what type of sealant would I use? Thanks Quote Link to comment Share on other sites More sharing options...
ScaniaPBman Posted December 26, 2018 Share Posted December 26, 2018 If you are going to seal the top of the windscreen have a good read of this older thread You need to be careful using any old silicone sealer on the screen, not all sealers are compatible with the sealer regularly used on screens. The one I purchased, as noted in this older thread, had a short shelf life amazingly. ScaniaPBman. 1 1 Quote Link to comment Share on other sites More sharing options...
addiosamigo Posted December 26, 2018 Author Share Posted December 26, 2018 In the end I managed to just push it back in. I didn't realise that the whole surround went into the groove, it just needed more of a push in and then down. I don't think thats the source of the leak though, I will need to investigate More.

addiosamigo Posted January 1, 2019 Author Share Posted January 1, 2019 I got the carpet up and it's soaked, doesn't smell of anything, just looks like rain water. It's wetter more inwards towards the drivers side. Could it be the pollen filter? Quote Link to comment Share on other sites More sharing options...

Common problem with the pollen filter housing Mine is soaking since ford replaced the pollen filter last October I complained last service and they billed me for a new housing 😂 how could I have broken it 1 Quote Link to comment Share on other sites More sharing options...

Cheers I'm 90% sure that's what it is, But regarding fixing it yourself; I too would like to know as I'll be spending the same amount of money at the dealers hoping they fix it correctly; I'm aswell have a go at fixing it myself, You will need a pollen filter as existing one will go mouldy after being wet or saturated is probably a better description of its current state, 1 Quote Link to comment Share on other sites More sharing options...

Got the glovebox out, got the fusebox down, removed the metal bracket (had to get a socket set for this) then got stuck on the bolts for the pollen filter cover. I needed 7mm socket but only had down to 8mm. I will buy a 7mm socket tommorow and continue! 1 Quote Link to comment Share on other sites More sharing options...

Great deal on the focus, The pollen filter housing leak is a known common problem though from 2005-2011 it's exactly the same focus just outter panels differ Another leak is in the boot when the seal around the rear spoiler bolts deteriorate; I've taken off the spoiler and applied silicone around the bolts prior to refitting much like a jam sandwich; Done it as preventative maintenance, 1 1 Quote Link to comment Share on other sites More sharing options...

I really don't think it is coolant as it's just rain water, no smell. I only noticed it when the rubber mat was wet and I looked underneath and saw that it was shining. Put some kitchen towel down for a few days and it soaked up a bit but when I took the carpet up I realised how bad it was! I'm going to try and remove the pollen filter today when I go and get the other socket. I'll let you know how it goes. The worse part is going to be getting the AC hose back into the glove box! I haven't got any leaks in the back yet, but I may work on that as a preventative measure. What exactly did you do? Cheers Quote Link to comment Share on other sites More sharing options...
Larkspeed_NL Posted January 3, 2019 Share Posted January 3, 2019 I had this same kind of issue with an escort, drove me nuts trying to find it, turned out to be a rust hole in the top of the firewall, you couldn't see it by looking under the dash or when the bonnet was open. I found it eventually when I stuck my hand up under where you cant see in the engine bay and my finger found the hole. Every time I drove in the rain the spray was getting in the hole and running down under the carpet into the footwell. We used to joke we had an escort with a built in swimming pool. So if the pollen filter housing is not wet I would start looking for hidden holes. 2 Quote Link to comment Share on other sites More sharing options...
addiosamigo Posted January 3, 2019 Author Share Posted January 3, 2019 As I feared the Pollen filter was brand new! Changed in April. Bone dry. Having looked further I can see no water coming down from anywhere, its all dry. No smell, just water. Having got it all up, I will dry the carpet out as much as I can, then monitor it weekly. So an update is I'm still none the wiser to the leak! 1 Quote Link to comment Share on other sites More sharing options...

So an update is I'm still none the wiser to the leak! Just a suggestion, look on the bulkhead at the rear of the engine, there should be a rubber hose which will look like it has disconnected from whatever it’s connected to. This hose is a drain to channel rainwater away to drop onto the ground. Check this hose isn’t clogged up with debris because if it is, I’d suspect the water to be building up and finding its way inside the car. I haven’t had this happen yet on my focus but I did have it happen on another car I had, the hose was sludged up with dead mushy leaves and once I cleared it, fixed the wet carpet problem.

Ah ok thanks Russ I'll check that! Is that on a MK2? Also where abouts am I looking? Cheers 1 Quote Link to comment Share on other sites More sharing options...

Cheers Yep, open the bonnet and it’s at the top of the firewall (slightly left of the centre) it’ll be hanging down. If I get a chance I’ll take a photo in the morning to show it’s position. If I remember rightly the diameter on mine is roughly about 10mm diameter and maybe a footish long. 1 Quote Link to comment Share on other sites More sharing options...
addiosamigo Posted January 6, 2019 Author Share Posted January 6, 2019 Just an update on the leak situation. The carpet is wet again! It's not soaking but enough to come through the dampener and saturate the carpet. There's no water in there so it's obviously been soaked up by the carpet. Now my feeling is it is either the defrosted water making its way into the car or the air con is leaking. The coolant is full so that's not leaking, (not sure if heater matrix is different). I used Aircon on my way to work and back again and it's started to make a whiring noise which I read means it could be out of refrigerent. That would make sense if it's leaking! So the saga continues! I will find this ***** leak! Quote Link to comment Share on other sites More sharing options...

Regarding the heater matrix, it's plumbed into the same loop as the engine i.e out of the engine, through the bulkhead into the matrix, back out of the bulkhead into the engine so if the matrix or matrix pipework was leaking you'd definitely notice a drop in coolant. 1 Quote Link to comment Share on other sites More sharing options...
