Mk7 Ford Fiesta Boot Leak Repair & Rear Bumper Removal
Вставка
- Опубліковано 4 бер 2022
- Having recently discovered water leaking into the boot and pooling in the spare wheel well of my Fiesta I have been trying to diagnose where it's coming from and this video covers the common areas gleaned from forum posts and suggestions and covers the removal of the rear bumper to access two common areas which are prone to leakage.

This is a fantastic video, I followed this and fixed my water leak, very much appreciated. No water, no leaks noticed now with the serve rain we have had recently in Feb ’24 (UK).
I followed this video and managed to stop all the water slipping into my Ford Fiesta Mk7 59 plate. The boot had water in it and it had also gone into the rear passenger carpets footwells. Took a while to dry out.
I think my water leak was coming from the two holes that are just covered up by tape, these are located behind the rear bumper, very poor design from Ford and also wear the main body meets the rear boot panel, just below the roof gutter as per the video.
I sealed the joints at the top between the main body and rear panels,
Changed both rear vents for brand new ones from Ford (approx. £20.00 each) and sealed the outer side of them with Tigerseal (purchased from Halfords - this is a great product, very flexible and rock solid)
Removed the old tape that was covering the two holes on either side of the rear bumper (tape was coming off and the holes were exposed) - used body filler and spray sealant to make this a permanent closure, sealed around the various grommets around the light fittings.
Ford Air Inlet vent part number: 4858452
I used the following products, purchased from Halfords
Gorilla Tape Black Extra Strong
ISOPN Body Filler P.40 with hardener
Davids ISOPON Aluminium Mesh
Halfords Anti-rust Primer Grey
Tigerseal Black 310ml - this is so good and extremely strong/flexible, highly recommend
Thank you again for this great video.
I find this very helpfull.
My tailgate started with condensation thats soaked the underside of my rear seat bench and water in wheel well and same right back corner as in this video! I think water is coming in these vents you are talking about on mine or the holes with tape on them.
Yes that will defo be the issue, I had the same problem. This is a very poor design by Ford.@@jaketaylor5470
Thanks for this video ! Discovered water leaking in to the boot area, both sides around the same time. Immediately replaced the rubber seals on the rear light units but found more water last week. Hose pipe test showed water coming is when sprayed from the top of the light unit and when sprayed below so must be holes behind bumper. Removed bumper to find air vent was missing on the drivers side. Explains the clunk I heard a few months back while driving. Also tape seals had come off almost exactly the same as yours. Vent replaced and holes sealed now. Water test today - wish me luck ! One tip: don’t leave the boot and doors open too long when working on this - interior lights stayed on throughout and drained the car battery !
I've just taken the rear bumper off and your video was a huge help, especially the tip about pushing the little rods holding the bumper to the wheel arch protector through from the front - I just used the short end of a smallish allen key to push them and then they pulled out easily with pliers, allowing me to push the plugs out forwards. No idea if I'll fix the leak but this video and your other one have given me lots of ideas of where to look for problems. Thanks very much!
Thanks for your Fiesta videos. I have water getting into my boot and after checking behind the lights everything appeared fine so going to follow your videos to remove the bumper and also seal up everything.
A good clear and well described video. I have the same problem so it will help me. Thank you.
Yes, Vice Grip is the best source of information to get your going to town rig back in shape 👍
subbed. ill be attempting this soon , same exact issue as yourself. i did take it to a garage to have new air flaps fitted, thinking that was the cause but it made no difference so this time i will do it myself and seal those tape holes. ill be following your progress so keep me updated .. thanks for a great video.
Thanks for the great walkthrough. Had to remove the bumper too for the exact same reason, namely shoddy work by Ford. Turned out mine was missing the tape over the 2 large holes in both side, no wonder a bit of water came in :) Cheers from Denmark.
Had no Idea this was so common Thanks!
this video help me so much! thank you very much sir!
Great video. Very helpful.
Thanks for the video,very informative 👍
I did this same repair exactly two years ago and then my trunk was then bone dry. I used flex seal tape instead. Sadly, I noticed a bit of water today in the back today after a heavy rain 😖
Great, informative video, thanks a lot.
Very entertaining and very informative, typical Ford bodge, should have been sealed properly when made
Gonna try that today, thanks a lot
Thanks mate. Really helped me. Same issue I think
Many thanks for this video. My fiesta has the same problem and the garage could not find the cause of the leakage...
Fingers crossed one of these things sorts it.
Snow covered and 10cm more tonight here in New Scotland (Nova Scotia). -15°C last night, but a balmy -5°C tonight. Good luck. Water leaks are almost as bad as electrical gremlins.
Yikes! Stay warm there. We're currently dry but still chilly.
Really helpful video. I am preparing everything to try this, following your guide. Just a quick question - when I take the bumper off will the fact that I have parking sensors make any difference? Is it just a case of disconnecting/unplugging them as I carefully take the bumper off? Any advice gratefully received as I am a new car DIYer. Thanks
I haven't seen one with sensors personally but I imagine they'll be a simple plug connection, just take care to lift the bumper away carefully to avoid pulling the wires.
Best sealant for this job is Granville windscreen silicone sealant from Halfords. Easy to use and goes off in 15 mins. I used self adhesive lead flashing to block the holes (only because l already had some)
Good to know, is 15 minutes long enough working time though?
It was ideal for me because l was working in a cramped garage during wet weather. You certainly don’t want to leave the cap off the stuff between applications!
Excellent video that helped me to finally deal with the leaks. Just one comment, use an other sealant as silicone sealants acidity and tends to cause corrosion. Other than that excellent video
That's helpful thank you. What type of sealant would you recommend?
@@spidiq8 i used polymax in The Netherlands available in the Uk from Griffon
@@arthurroubos9178 Thanks, I'll have a look for that.
Is the black bumper cover piece just clipped into place? Mine came off when i went through some water so I need to replace it.
Yes it just clips on.
Excellent video thank you! Have you had any problems finding water also in driver footwells? Seen a video online, possibly door card membrane??
I haven't but if it's front footwells only I'd suspect the door membrane. That's always been a common one.
Check the drip panel below the windscreen for dirt build up which causes water to overflow an run inside car below wiper motor. I have recently sorted this problem out on a 2009 Fiesta and now working on the rear leaks :(
@@fsherryff49 Hi, I have the same problem on my fiesta under the passenger seat mats, especially the rear one fills with water, can you explain how you solved it.
thank you
Do you have any recommendations for different clips for putting it back on?
The clips on my car wont get loose, im more likely to break the part on the car than getting the clips out.
I think its a shame that this simple job is such a pain. When I remove it now, I want to use better clips to mage it an easier job next time around.
I'm afraid I don't know of any offhand, I'd recommend a ford owners forum or similar as they're usually a wealth of aftermarket parts knowledge.
Sadly it seems most things on modern cars are just not made to be user friendly to strip and reassemble and service centres will have a bucket full of spare clips as needed.
Hi, great video thanks for the information. Made me chuckle with the McDonald's stir stick 🤣. I'm having this water issue on my wife's car. Seems to be definitely coming in from the back and due to recent rain for the first time has travelled into the rear footwell. Did this trick solve your issue? Also any tips for getting the car dry again?
The only way to dry is to remove the carpets. The water soaks the sound deadening foam first before reaching the carpet so you need to get it out and either squeeze or wet vac the foam.
I have noticed a little ingress again recently but we've had torrential heavy rain and some of the sealant I used has cracked so come spring/summer I'll be removing and replacing it with something more flexible.
@@spidiq8 ah I was hoping to avoid removing the carpets but I think I know someone with a wet/dry vacuum I can borrow.
When you say more flexible sealant I take it you mean rtv?
@@zoeandbengamble5353 I'm going with bathroom silicone. I have a tube ready. The tube I used in the video was supposedly rtv but it was unlike the rtv I used way back when on my BMW K1100LT water/oil pump change video which was very flexible and rubbery even months after with numerous heat cycles in direct contact with an engine.
This stuff has cracked and dried.
I believe there are machines that valeters use which can vacuum moisture to a higher degree from fitted car upholstery but that's only based on a few videos I've seen. It might be worth asking though as I fully understand removing carpet is a chore.
Hows it going ? , have you managed to stop the leak ? . After looking at mine , the water seems to be leaking in from higher up from the weld seals near the roof strips. ive used silkafex down the cannels and stopped it from the drivers side rear but just resealed the left side as it was still letting in slightly.
After a lot of poking about I think I've finally sorted it. There was more than one point of ingress and the holes behind the bumper being sealed definitely showed a reduced leakage. I do have a montage of clips to edit and upload once I'm happy it's dry in there.
@@spidiq8 looking forward to seeing it mate :)
@@081064perry Hopefully it won't be long before I can upload it. Fingers crossed I've sorted it now. It seems to be the bane of many ford owners and it's otherwise a great little car.
Great video! I'm currently working on a similar project. Could you please help us out by telling us the year of your mk7 Fiesta? Thanks so much.
Mines an 09, I believe this problem affects all years of this shape though.
Many thanks for your videos spidiq8. I have the same issue and managed to get the bumper off yesterday and have sealed the two holes. both the top holes were uncovered as the original tape had peeled away. I decided to cover that whole area with sealant rather than just fill the two holes - did you consider that? Curious as to why you covered it with tape and then sealant on the edges. I was going to put tape over the sealant but now wondering whether the tape will actually stick on the sealant. I also have an issue with the front doors, certainly drivers side where water is coming through the door seal, have tried to glue it but will look at how easy (or hard) it is to replace them myself!
Glad it helped. I felt the holes might be too big for just sealant. Sorry I can't help re the door seals as I've not looked at those.
@@spidiq8 I did put tape inside i.e. behind the holes first as you suggested and then sealed over. just spread it over a wider area than the two holes. Will put some water over it later I think it see if its worked - bumper is still off so may as well before I put it back on.
@@aswadqadeer947 I see. Fingers crossed it works for you. It's surprised me how common a problem this is.
Hi mate, just a quick question because this is has been bugging me for some time. By the looks of it, the plastic trim that's on the rear bumper can just be removed with some slight force, is this correct as I really want to remove mine and paint it over.
The bit that's grey? Yes that's right. I recommend as with any plastic trim you do it in summer or in a warm garage as plastic gets more brittle in the cold.
What is purpose of this holes that were tapped? Why are they there in first place? To leak water and make problems!?
My Fiesta leaks on front left side of boot corner.
You got me there.
I have no idea what use they're for. I could only assume that they were for one specific model and it was cheaper to have only one panel pressed?
@@spidiq8 Makes sense
Thanks for that Video, but you should not use bath silicon. It contents ingredients causing corrosion and is not covering low temperature.
Thanks for the tip!
Looks like the same boot leak I’ve got after checking the other places. I’ll have to whip off the rear bumper and see what’s going on.
Could I get away with putting the bumper straight back on after taping/sealing any bits? I live in a terraced flat and my car is on the street 🤷🏼♂️
@@WIZWARDCODWAW Hope this solves it for you. You can put it straight back on yes. I left mine overnight just to check the sealant and the vents and holes first.
Quick tip. Take off the lower grey trim panel first on the bumper. Imani
Unsnap from underneath and wiggle out and you can see the 2 lower bungs and remove them easier. I discovered this on refitting and am going to upload a very short clip showing it shortly.
@@spidiq8 ok thank you! Was trying to get bumper clips off with flathead screwdriver but mine seem like antiques...getting myself a clip remover tool and a bunch of new clips as feel like they’re gonna snap!
@@WIZWARDCODWAW Not a bad idea to have replacements. Mine aren't incredible but they're usable. Also the ones which hold the mudflaps and wheel arch liner, you can push the pins from the arch side. Easier with the wheel removed but you can push them completely through and remove them easier then collect the pins from behind the liner if they don't fall out.
@@spidiq8 Finally got round to doing this. Thanks again for the tutorial, invaluable. Although sadly it rained yesterday and water is still getting into the boot, same place (car hasn't been moved either, so I guess it is dripping from above?). The next places I am checking is the roof trim bits...and then maybe re-check the hinges again. Frustrating because when i pour lots of water in various places it doesn't get in!! Rain must gently tickle through somewhere.
You could of fitted some grommets in the holes ? That’s what I’m just about to do
I could have if I had some.
Dry? In Scotland? In March? Yeah, right. That's Barbados or Fuerteventura! ;⁰)
Hahaha I wish it bloody was. Believe me, I'm as surprised as you. 2 days of dry in march! It's not normal, there was even a bit of sun.
@@spidiq8 "even a bit of sun"......that's the spirit Che.
Did this still work for you?? 😊
It did but has started leaking agian, I have noticed that the silicone I used on the top of the boot seams has dried and cracked so need to clean off and redo with better stuff.
You could have simple put the fixed vent onto the opposite side.
Achieving what?
will do this on sunday, i put silicone on trunk doors, where they just pointwelded these panels. God this car is poorly made
I dont umderstand for the life of my how the water rises souch it.flood the whole boot?
It either runs down through a gap or is thrown up by the wheels when driving on wet roads and in rain.
Pretty straightforward.
Wiper grommet!
Not a chance, not where the water is leaking in, it would have to undergo some epic re routing to make it appear where it is.
I have sealed from top to bottom.
Lifted the gutter strip as there were cracks for about 6" up there, sealed.
Around the top joins, all sealed.
Taken out the vent, sealed.
The holes covered in tape, sealed.
Still getting water in. watering can full from the top and I get some in the corner above the wheel well. Tried shining a torch through all the holes and I get the feeling it is coming from behind the bumper somehow still but more from the middle but I can't see where from.
Frustrating isn't it. I'm hoping I've finally sorted mine and have another update to film the last (fingers crossed) bit and edit and upload.
You'd think there were only do many places water could enter.
@@spidiq8 One thing I have found is that on the side where the water is coming in, the bumper bracket is missing the bottom4-5".
it all clips in but the bottom area that curves areound the wheel arch and has the tiny mudflap, all gone.
Now when i had the bumper off I ran a watering can of water down from the middle of the top of the hatch so it runs down all the gutterways, and this time there was no ingress. There was a tiny bit of damp around the rubber flaps on the vent but that's it.
I'm wondering if that bottom portion of the bumper bracket also deflects water away from the vent? or is the water getting in behind the rivets holding the bumper bracket on?
I have ordered a replacement bracket from ebay, and the proper plastic coated rivets and I am going to make sure that I put some sealer around every rivet hole.
I also have a spray tin of waxoyl that I may spray all over the rivets holding the metal bumper bar onto the rear panel. Just in case if someone had bumped the back of the car the panel is slightly warped there and water is getting in there.
if that doesn't work I have no idea, lol.
@@soopafamicom If I'm picturing that correctly that's where the wheel arch liner pops onto the bumper and the little mudflap, I'd imagine that would allow more water to spray from the tyre and possibly into the vent?
@@spidiq8 Yes that's it.
the whole area there is missing, in the vids where it mentions to get to there you have to take out a bolt under the liner to remove the bumper...all gone.
I wonder though with how it is shaped it channels water down below the level of the vent. With it missing, water could be bouncing back from the inside of the bumper, soaking the vent and overwhelming the capacity of the flaps to keep out water.
Just a theory.
@@soopafamicom That would be a good guess and one I'd assume. That wheel arch liner will stop a lot of water spray
Treat yourself to a replacement rear light rubber seal.
I did, covered in the videos relating to this.
Blanking tape 😂😂😂😂 what a stupid design why didn't they just put rubber bungs in holes
Behave, that's a sensible solution.
