Mk7 Ford Fiesta Boot Leak Repair - Update Final

[@AnilSharma-s3w3u]

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. 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.

Glad it helped and thanks for the part numbers for the vents etc. Very useful.

I have a Mk7 Fiesta with the same issue. I followed all the advice and tips and was still getting heavy water ingress. I finally located the problem to the near-side roof channel gutter at the rear of car. I removed the old roof channel trim moulding and found a rusty hole. I cleaned it out and filled it with No Nonsense X8 black hybrid sealant and installed a new rubber trim moulding purchased from Ford Official parts website for £33.23. Since then we’ve had several heavy downpours and it’s bone dry inside the boot.

Bought the same model fiesta today , and saw that the owner had done the repair in the same area at the top with silicone. Googled it and this vid popped up. We bought the car. Will need to remove the boot panels properly to check . Thanks for your effort putting these vids together. Well executed

[@spidiq8]

Fingers crossed yours is dry inside. It seems to be a very common problem.

[@amarpatel3154]

@@spidiq8 cheers mate , I did slide my hand inside the boot liners where you put the tissues and felt bone dry. The wells looked dry too. Will need to see when driving in rain .

[@mh24728234]

finally !! it was the roof . seam weld under rubber strips had failed .after 3 weeks of scratching my head ,and cursing ,what a job .

[@spidiq8]

That's really useful info thank you. So the strips that run front to back? Did they come off easily enough?

[@Tony66424]

Yep, same on my sons car..we did this job two years ago

[@chrisgerb6823]

@tony66424 How do you Remove the strips?

[@Tony66424]

@@chrisgerb6823 hey Chris, we had to slowly prise them up bit by bit without bending them. In hindsight we only needed to prise up a couple of cm as the leak was right at the front, you could see it even without lifting the strips. Not sure how we stuck them down again, probably with some RTV

[@Nico-cg2sw]

​@@spidiq8had the same problem on my 2009 Ford Fiesta, yes pull them off gently, we sealed the holes with glue and glued back on the strips

[@Wellibob68]

I had the very same issue, and the drivers side too (2014 fiesta zetec 1.25). I had the bumper removed and sealed up same as you and also had a small hole which had appear along a body join 👀. Sealed too. Water was still getting in although small amounts. Removed rear lights and sealed them same as you and the joins around the tailgate roof they were sealed too (previously). Let see what happens now. 👀

[@MarkGarnham-s2s]

My daughter has this problem with both sides, we thought we fixed it with the silicon on the passenger side, but water is still coming in. I see you got some genuine ford seals, are you able to send me a link to buy these as i am struggling to find these on line

[@user-zs4tj5ll7k]

Good stuff mate thanks i don't fancy taking the bumper off

[@DeliciouslySaby]

Wow you are so talented in lots of things!!

[@spidiq8]

Thank you, this has been more a case of banging my head in frustration and trying one thing at a time. Hopefully this has sorted it.

[@jeffmee763]

Window screen sealer is really good on this sort of stuff.

[@spidiq8]

Handy, thanks.

[@robertwilliams1147]

Can leak from under end of roof rail channel

[@MrHeinzz777]

Do you 'glue' the seal of the taillights to the body with the silicone, or do you let te silicone cure to make another layer of seal?

[@spidiq8]

I tried 'gluing' the seal in place so it would create a watertight seal. However it didn't work and I replaced the seals with new.

[@herrlip72]

14:15 the seals, did you glue the new seals on? Also did you glue the two ends together before fitting?

[@spidiq8]

Fitted on and the gap sealed with silicone so not glued with glue but yes. the ends sealed after fitting and started and finished at the bottom of the lights as that's the area most likely to weep water in.

[@RocketSailing]

Maby molycote 111 silicongrease on the lights gaskets. My sailboat is prone to leakage in some areas. Butyltape and sikaflex sealants are good stuff

[@spidiq8]

Thanks for the info. The sealing problem with the old ones was definitely due to deformity over time though I think. The new ones are holding up though I'll keep checking them for a while yet. Sadly this seems a very common problem with both Fiestas and Focuses of this model type.

[@arslan4638]

@10:50 You put some silicone on that rubber seal ? Or this is some grease that make seal after drying ? At end of video, You said you have bought new rubber seals for stoplights ?

[@spidiq8]

Yes that was my attempt to make that seal work. It was unsuccessful and I bought replacement seals.

[@arslan4638]

@@spidiq8 thx for Your time to read and reply on my comment. Going to my Ford dealership for sealings and will do as like You have done. Luckly they don't build ships 😂

[@spidiq8]

@@arslan4638 Lol, yes indeed. I'm amazed how many people have had this same problem. Good luck with yours.

[@stephenmurphy7064]

@@spidiq8 Please can you share where you bought the replacement seals from as I have the same issue. Was it from a Ford dealership or an online store of some sort? Thanks so much

[@spidiq8]

@@stephenmurphy7064 It was an eBay store but official ford parts. I just searched for replacement seals and the non OEM ones weren't much cheaper.

[@cassw8951]

Has your leak problem been solved then? Great video, thanks!

[@54356776]

Are there any videos on how to remove the panels/carpets ?

[@spidiq8]

Not by me, a search of youtube should reveal any.

[@brax9503]

Hi Did you manage to sort out the leaks? On the fiesta

[@spidiq8]

Yes, however it started again though I noticed that the silicone I used to seal the seams at the top of the boot lids has started drying and cracking so I need to remove it and try a different one.

[@julieposte7972]

Water is in the boot and also running into boot catch, which has caused no end of electrical issues, I had the boot catch replaced as it was rusty, where is it coming in?

[@spidiq8]

If it's none of the areas I cover in the videos then I'm sorry to say I don't know.

[@Sarah-gr2rg]

as @@spidiq8 points to, Julie you could try under the roof gutter strips - I’m just fixing a leak that’s been flooding my boot and my rear passenger footwell (and into the front footwell!)! Vacuumed out over 3L of water today. They just peeled off with some brute force, and I found cracks under them on both sides - sealing with silicone and taping them before reattaching, and hoping for the best. Not such a fan of my mobile mini-ice rink in the cold! Thanks so much for your videos @spidiq8 - you, along with other similarly leaky Tubers, have empowered me to tackle my moist-mobile.

[@spidiq8]

[@thomasedward9065]

Nice omega chrono stop proberbly 1969 ide say is the car still dry aswell

[@itsagoal182]

No disrespect mate, but you don’t half waffle on, try and get to the point a bit more. Dont put sealant on the rubber seal for the rear lights, you want to be able to remove the light cluster at a later date to change bulbs. Don’t use household silicon either, use tiger seal or all weather sealant.

[@christophercooper9762]

Your just making a mess
