How to Fix the Honda Civic MK8 Boot/Trunk Water Leak

The water leaking into the MK8 Honda Civic 2006-2011 is a common fault of that model and Mark. It makes the extra luggage or spare wheel compartment unusable. In this video, I figure out a way to fix this issue by using paint lacquer.

Thanks for the video, sir. While its an old video, it's still helping people out.

[@Fin6531]

I had the same problem and followed your steps to stop the water coming through. It seems to have worked perfectly! Thank you very much 😁

[@yamyam3905]

Before taking things apart , run sealant along bottom of tailgate glass , this was where my leak was coming from .

[@NonConformist-ys4wr]

This is the main cause of all civic boot leaks .... 💯 %

[@SMACKYOURB1TCHUP]

Thanks ! had a puddle in bottom of boot. Followed your guide. Boot 100% dry today after a night of heavy rain. I did also run captain toms creaking crack along the top of the spoiler where it meets the glass. All the way across in the gap. That is also an area where leak can happen with the spoiler screws. Worth doing at same time since it doesnt require any extra dissasembly of lights etc.

I have a Type S which I sort out the leak in my boot and the main area where the water enter into the boot is the boot lid around the number plate area on the inside, Where some clips inserted in the metal which get a bit weak and a few unnecessary hole are there too which need bonging up. “Very difficult to work on..Many ppl who have these Hondas 2006-2011don’t know. I had so much water in mines before I sorted it then when I move off or brake I could hear the moving water.

[@dean3703]

Ive got the same and just found this out today, will investigate but thanks for this

[@Fotiossone]

Thanks buddy! This solved my problem and saved me a lot of money! I bought a universal lacquer spray from Halfords. I waited for a dry day, cleaned well with a wheels spray I had, then I applied three coats of this universal lacquer and problem is solved. I had dried the boot with an industrial sponge as well as I could and after a full day of rain I noticed it's still dry. I'll monitor it from time to time but so far so good. Thanks again for sharing this!

[@EducationPineapple]

Well done...hope to still see many more saved MK8 civics on the road in years to come. They deserve it.

[@AWMJoeyjoejoe]

I didn't know there was such a thing as an industrial sponge. 😂

[@robertwalsh5203]

For my 2008 civic the boot leak was coming from the diesel cap latch, not a huge job but finding the leak was definitely the hardest part..

[@View-From-Above]

how did you solve problem? Did you silicone around cap?

[@stars7902]

Je vois que tu parles aussi français ! Alors vraiment un tout grand merci ! Je vais essayer d'arranger ça demain ❤️

[@hibbs79]

1st. Interesting video I have a civic and although no leaks yet I am waiting for the day. Thanks for sharing. 👍

[@hippo319]

Ive had a boot leak - just unblocked the drain in the fuel filler using a cable tie - hopefully that will fix it!

[@megafilmsrainbow5236]

I have sme problem I have water in fuel cup and in the trunk thnx for share this vydeo .

[@willtato8778]

Thanks for the video. Not sure if you still have the car, but can you remember how you took off the trim piece at 7:26? Was it just a simple upwards pulling motion to 'unclick' it out of it's position?

[@EducationPineapple]

Push the sticky out tab at the rear of the roof trim towards the front of the car then it just lifts and other connectors just pop out.

[@willtato8778]

​@EducationPineapple sorry, I was referring to that large plastic piece at the bottom opening of the boot (the piece where the boot lock mechanism (the loop shaped thing) goes through the hole on the top.

[@EducationPineapple]

Pull it at the bottom evenly and it should pop out.@@willtato8778

[@bernardCHRISTopher]

Thanks for video. I have leaking in boot and nearside back seat. Ill definitely give this a try.

[@Tintoycar]

Did it work?

[@DirigiblePlum69]

I couldn't even get my roof rack thing off!.

[@TheAnnieSisters]

I have enjoyed your thorough and lengthy videos of these honda issues. As I have been standing and pondering for weeks over my multiple leaks. My boot tire well went unseen for who knows how long as the black sound proofing stuff that is stuck to the metal turned to goop. If you touch it you can literally smear it and pull it out. I have no idea what this is called, I tried to flatten it out but it is still soft and not hard, can you suggest anything to put over the top to harden it again as nothing can touch it without being covered in black tar or grease stuff

[@EducationPineapple]

Anything that has been damaged from water to that extent should be torn out. Then fix the issue as shown. If you don't want things banging around then just put an old blanket in there.

[@thebanditsix]

I had same problem on my EP3 with water in the boot,water gets in through the roof gutter, run's down the inside of the rear pillar into the boot,I used VTEC black silicone sealer from euro car parts, stopped the leak.

[@andresilvasophisma]

Was this because of the two things on the roof? I'm suspecting mine is leaking to some extent, as sometimes the windows arr foggy, even without driving it for a few days. It might be just a slight leak.

[@giovannineron1865]

J'ai procédé de la même manière avec les même conclusions il y a plusieurs années. Les joints de carrosserie..... Pour l avant sa fait 3 fois que je démonte la voiture en 7 ans et aujourd'hui jusqu'au ailes j ai des photos si tu veux.? Pour moi ca reste les joints de carrosserie de la gouttière a partir du bas du pare-brise jusqu'au niveau de la suspension moteur.

[@EducationPineapple]

Nous devons faire ce que nous pouvons pour garder ces vieilles voitures en état de marche. Bonne économie de carburant, moteur et système de démarrage puissants. Bonne électronique. Bon design. Corps et suspension solides. Au Royaume-Uni, après ce MK 8, le MK 9 est devenu trop compliqué, mais j'aurai probablement un jour le break MK9 pour le grand coffre à bagages.

[@arronb1]

Thanks for the video really helpful. I was going to lay down some sealant since then in the basin well I've drilled some holes for now to keep the water away. So your saying lacquer instead of sealant ? How's it been since.

[@EducationPineapple]

Needs a new spray every year or so, so far very waterproofed.

[@wackadakka3134]

use tigerseal and it will be done ......., forget about it done

[@tobyprior8839]

It seems there is quite a few people having this issue recently as I noticed a couple of other pretty recent videos on here with this issue and I also have it on the passenger side. I dont know if you know it but there is a Civic forum called civinfo and there is loads of people on there with this issue as well and a lot of people like yourself believe its the seam sealent at the top thats gone and thats where it is getting in. Like you I was not keen on trying bathroom sealant to try and fix the problem so I have tried the Captain Tollys for now to see if that has done the trick as that dries clear. I also brought some Sikaflex SBT+ clear from screwfix and put a bead of that around the rubber grommit for the wiring harness. I actually stripped out my boot to get a better look at where it was leaking in at first I thought it was behind the indicator light so I removed that as well but it wasnt there but I did find the seam sealent there had also cracked and had a hole in it so I filled that in with Sikaflex as well and ran a bead on top of the old seam sealent. I only did this yesterday so I dont know if it has worked yet but if its still leaking I might give the Laquer idea a go so cheers for the suggestion. I hope yours is still leak free!

[@richardthered]

Did it work?

[@tobyprior8839]

@@richardthered Yes for now at least touchwood it's still dry and we have had days of some pretty heavy rain. For around £15 in total for the silicon and captain tollys I didn't feel like I had a lot to lose by at least trying it.

@@tobyprior8839 That is great news. I have noticed a dampness in the bottom of my boot. First thing im going to do is them roof seems. I need to strip the carpet out also and check for any rust etc. Looks like getting the carpet out is a chore in itself. Wish me luck lol

So i need just to clean that water flow under the trims ?

That will not work...please watch the video

[@bernardCHRISTopher]

I did this with my car but it was raining on the day.does it need to be a dry day as it doesn't seem to have worked? Like a pond in boot and back seat

[@EducationPineapple]

I would recommend drying the area up as much as possible...wait for a dry spell to super dry it...take off the roof strips...wipe down then clean down with alcohol wipes....spray with slow acting lacquer like described and it should work. If you spray lacquer on top of water filled holes the lacquer cannot penetrate into those holes.

[@bernardCHRISTopher]

@@EducationPineapple thanks for speedy reply. Ill try again when theres a dry spell. It could be a while as i live in the west of Ireland.

[@bernardCHRISTopher]

Hey man just to let you know my car started to dry out after 2 weeka or so. Iv had car 3 or 4 years and its always stunk through the winter from being soaked. Its bone dry the last month or more. Ill reapply when weather gets bit warmer. Thanks a million i was years trying figure it out.

[@AM-wt8qi]

Could be from boot lid and dripping down ?

[@EducationPineapple]

not boot lid

[@Tintoycar]

Hello, when I translate "lacquer" in Dutch I get "paint", is it paint?

[@EducationPineapple]

When you paint a car on bare metal, you place a layer of grey rust proof paint first, then the colour paint (blue on my car), then lastly the lacquer .... the lacquer is the transparent coating that goes on top of paint to protect the paint.

[@AC-db4ek]

how come all hondas have leaking? I can't believe these design flaws.

[@EducationPineapple]

Look on the bright side, all Honda's have engines that can last 300,000 miles.

[@AC-db4ek]

@@EducationPineapple other brands too but without water leakings.

[@jakubgrzanka5107]

Oj mate not with the lacquer... It will do the job but not gonna fix the problem for years, as the car moves and the body works, the lacquer will simply start to crack with the time and your problem might happen again... But good searching for the leak

[@EducationPineapple]

Would that same logic apply to the rest of the lacquer on your car's body? Or do you assume that part of the car has extra movement between the adjoining surfaces? Lacquer, I found, seeped deep into the minute holes, gave extra grip and penetration because of the low viscosity compared with say bathroom silicon, easy and natural on the eye for resale value, and solved the problem 100% since application.
