Just showing you how I fixed my small head gasket leak with a product called K-Seal. This product seems to have a high amount of positive reviews on Amazon so I decided to give it a shot to fix my head gasket leak, PERMANENTLY. Link: amzn.to/2NOrre7
Here's all the products related to this video!

Update* Leak did stop but it wasn't from a head gasket leak it came from somewhere else I have no clue wear. Planning on doing a cooling system flush now so that this stuff doesn't wind up clogging small passages in my cooling system.

NOTE: My coolant leak was very small at the time only had to replace half a litre of Coolant every 5000 Kilometers or so. This product may not work if you have a large coolant leak.
Disclaimer: I (Darksyne) am not sponsored by K-Seal I bought this with my own money and take no responsibility for any damage this product may cause while in your car.
Update: I made this video 2 weeks ago and coolant level hasn't dropped, so far this product is working, I plan to do a flush once the weather gets warmer to prevent any possible clogs in the system.

THIS STUFF WORKS !!!🎉👍👌 like a charm 😁 I have 351,266 miles on my truck[1997 dodge ram 1500] all original. The Water pump just broke 40 minutes ago & fluids were everywhere. I put this K-SEAL stuff in and not only did it fix the water pump leak it also fixed my head gasket. I've been blowing white smoke for almost a year 😲 Now, no more like smoke😇 I'm driving from Reno Nevada to Tahoe with no leaks and my running temperature has always been right at or around 200 now it's running at or around 190 to 200. THIS STUFF WORKS🎉👍😎😲😁

@TIYX 4 года назад

You know when a water pump leaks (usually) that means it is shot. The bear on the water pump acts as a seal. When the bearing goes the water pump then leaks to let you know the bearing is shot. But it could just be the gasket leaking.

@arielaceves5806 2 года назад

Funny I come across this comment. I too drive from Reno to S. Tahoe at least twice a week. The radiator cap broke on my car and leaked all of the coolant and of course over heated. I noticed I was loosing coolant...ugh! I just poured this into my cooling system, hope it works!

@nj_beatz Год назад

Just bought this for my 8th gen civic fd. My radiator had small bubbles and pressure every time I took it for a spin (possible pinhole leak in the head gasket). Tried it today, drained some coolant first and put some directly to the top radiator hose then mixed some to the coolant I returned. I only used maybe 3/4 of the bottle since my cooling system only has 5.5 liters of coolant. And wow! the results are very positive! No more pressure and bubbles on the radiator. And the car felt smoother and responsive no more power loss after driving it for an hour. This is a real game changer! Super impressed with this K-seal. Will observe it more for a couple of days, but the initial results are promising! Excellent product!

@rons9197 3 года назад

93 Honda Accord 265,000 miles. Stopped leak I had in the head gasket. Added to coolant for 500 miles then drained then put distilled water for 400 miles. Drained distilled water and replaced with 50/50 antifreeze. No leaks at all after a couple hundred more miles.No clogs in heater core it is working as is the radiator. Amazing no leaks now but I will be replacing the head n head gasket.

@geraldos9094 3 месяца назад

Man, I just poured some K Seal into my water reservoir, after a mechanic just told me my gasket around my water pump is leaking. Haven’t seen a drip under my car in 2 days. I hope it holds because it’s a $2K job to put a water pump in this Land Rover Discovery.

@mikemilano7701 4 года назад

Make sure you read the bottle, these small bottles are supposed to treat up to 22 quarts of coolant so if your car only takes 8 quarts of coolant you should only use half a bottle. Especially if you don’t have an expansion tank for say a classic car it will completely clog your radiator and cause other problems. Make sure you fully read instructions prior to use!! Good luck with it, it worked for me in the past!

@Darksyne 4 года назад

yeah I think I mentioned if your car has a small cooling capacity like the older civic's, you don't need to use the whole bottle. But if you have a big truck that takes a lot of coolant, then you should use K-Seal HD which is a bigger bottle for those heavy duty cooling systems.

My car was leaking as if someone was pissing! I had previously fix 2 freeze plug in the same day. After I fix those, I had another leak in the back side of the engine, in which was really hard to get it to and did not want to bother with having to replace that freeze plug. I watch this video after thinking about engine coolant leak seal. When I saw this video, I had no doubt that leak seal would do the trick. I I used the same item, name K Seal after finding it at a local O'Reilly's parts store. The price was $36.... And was worth every penny of it! It work within 30 seconds!!! I have no more leaks!!!! That stuff works like a charm!!!! Thanks for the video! You would get a five star rating from me!!!

I went to auto zone bought a bottle of this and a quart of valvoline for the ol gal and let me tell you I'm riding around Phoenix in 108 degree heat with a/c on and not regurgitating out the overflow anymore from exhaust gases in the coolant this stuff is a miracle. yes one day I will pull the heads and get to the gasket and provide tlc but this helped for certain

@hssumm 4 года назад

Works as intended...... before you pour it in the radiator, run engine for 10 minutes. Do not over heat. Add coolant to just about full then top off with K-seal. Run heater full blast for about 15 minutes. Shut engine off and allow to cool....at least 24 hrs. It worked for me.

Nothing serious just normal water vapors from the condensation that builds up in the exhaust, so the car is in good health still. This stuff works but remember to flush out the extras once the leak is fixed so it doesn't clog the system.

@samhicks97 3 года назад

*This. Product. Works.* Real talk, I had a 'leak" it was more of a torrential downpour on the heatercore, and I drive a 64' Dodge custom 880. And yes there are no aftermarket heatercores for this car, so I was at a loss on how I was going to get the heater working again, and I was short on funds to get a re-core at a radiator shop. Lo and behold I tried K-seal and it stopped the steady stream of coolant that was pouring out. Quite unexpected for a sealer to work even on a gaping hole. So if you have a slow drip of coolant, I'm confident that K-seal can plug up that pin hole leak. Hell I'd even dare say i had the worst leak possible to even let a sealer take care of the hole. I gave the K-seal a run for it's money, and it delivered. Better than bars leak, bars leak sealer didn't even do anything to seal up the hole. Recomend using this product, I'd still advise on getting a permanent fix, broken part/ heater core.

K seal clogged my radiator by using it the way you did. That's why it says to add to the reservoir rather than the radiator itself. It will sit on top of the flues and not let water pass and cause overheating. It really needs to be diluted first before entering the radiator

I used a bottle of Steel Seal to fix my head gasket, drained the coolant, removed the thermostat, flushed the cooling system really good, Then use a radiator cleaner to clean the cooling system , Make sure to flush out all the cleaner 100%, When engine is 100% cold add steel seal with distilled water, turn heater on high & let idle for 30 mins with the radiator cap off........Let it cool for 1 hour the let idle again for 30 mins with the radiator cap on...........next morning let it idle for another 30 mins then removed all water from the system to let the steel seal cure for 24 hours, Replace the thermostat, fill with coolant and your good to go.

It may not say it, but if I were going to use it, I would remove the thermostat if you pour the radiator so it circulates immediately.

Tip. 🤔 When ever a product says, shake well before use, if it's an arisaul can or, something to that effect, make sure the cap is on tight! (if afflicable) and let it sit on your bench, up side 👆 down, 👇 for 3 or 4 minutes, then shake the product, the recommend amount of time. (Depending on the shape of the container, you might want to set "blocks" or "bricks" 🧱 around the container before, your leaving it on your bench, this will prevent it from tipping) This will help, free up, everything that settled to the bottom of the container, since it was manufactured, shipped and stored. 👍

@gregorythoman8281 6 лет назад

If you have a head gasket leak you can easily tell by checking your oil. It it looks like a milkshake you have coolant in your oil which means you have blown head gasket.

@Theywaswrong 3 года назад

Coolant leak could be going into the exhaust system and out the tail pipe. Head gasket leak doesn't always go in the oil or vice versa. If you oil looks good and you dont see any oil in your water BUT you are losing coolant, its going out the tailpipe. A bad leak will have a good bit of white smoke, steam. A very small leak you may not notice it but if you are losing water and its not in the oil, its going out the tailpipe.

Not completely empty. Should just be low enough so you could pour the whole bottle in it.

@usamakamal2092 Год назад

My radiator is not holding any water at all. Do you think it will work?

@jessicafaith8439 5 лет назад

Will this product damage my system if there is no leak? My vehicle shows several signs of a possible blown head gasket.... But I have no way of ascertaining for certain

@Darksyne 5 лет назад

You can have a mechanic perform a head-gasket leak test or your car would burn a lot more white smoke than normal and smell sweet if it's burning. So far the K-Seal hasn't damaged anything in my car since I poured it in years ago. Once I noticed the leak was gone, I flushed my old coolant out with new coolant and made sure the un-used K-Seal was removed before it caused a clog. Hope this helps!

If the leak comes back, you can get another bottle for free. Or says it on the back of the bottle.

@at1838 2 года назад

Does anyone know, does it matter whether you add to a cold or warm engine? Instructions say it does not matter. Do you think it is better to add to a warm engine to make sure the thermostat is open and the coolant is flowing? Does it matter whether I am using this for a head gasket versus another type of leak? thanks so much for the video!

@Darksyne 2 года назад

It doesn’t matter but you should be careful when the engine is warmed up because then the cooling system is pressurized.

START CAR RUN HEATER FULL BLAST THEN OPEN THE HOOD AND RADIATOR CAPP PLACE FUNNLE THEN START POURING SLOWLY UNTIL THE RADIATOR IS FULL CLOSE RADIATOR THEN PUT WATER IN JUG AGIAN AND ADD TO RESIVIOR....DONE GO RIDE AROUND FOR A BIT AND YOUR DONE. .....PS..

Nice! Glad to hear it worked for another person. Btw they make a K-Seal specifically for heavy duty trucks that comes in a bigger bottle so that you don't have to spend extra money buying multiple regular bottles. It's called K-Seal HD I think.

@josephbohme7917 7 лет назад

even so thermostat should be removed if you want it to work more easily

Joseph Böhme too much work on this engine. The instructions on this product doesn't require you to remove the thermostat anyway. I warmed up the car and cooled it off enough so I'm able to remove the rad cap.

Also car is losing power.... I know it's the head gasket.. Do you think this would work for me... Cheers guys....

@Darksyne 6 лет назад

Yeah sounds like a severe blown head-gasket. First I recommend changing the oil and coolant then if you want to try to repair with K-Seal then I recommend the K-Seal Permeant Block and Head-Gasket Sealer: amzn.to/2PbqQ6R Since that's a more heavy duty product meant for blown head-gaskets. The K-Seal is meant for slow leaks and minor headgasket leaks so I recommend trying the K-Seal Block and Head-gasket specific sealer. Just remember to change the oil and coolant first to avoid cross-contamination.

@dawnlokki4734 6 лет назад

@@Darksyne ... Wow..Severe.... .Sounds terminal.😕👍

@Darksyne 6 лет назад

It can be fixed, it's only terminal when your engine stops working :p But once you see a milking colour in the oil, that means coolant and oil is mixing so you should to something sooner rather than later. That's why I recommend the K-Seal Headgasket and Block seal because its a stronger product than the K-Seal from this video for larger leaks like in your car.

@dawnlokki4734 6 лет назад

@@Darksyne ...Very much appreciated. .. In fact the mechanic checked it over today and the oil only has a slight discoloration at the moment and not like "milkshake" 😆 yet..... Clearly mixing. ..

I have purchased this product but I would like to know the correct way to use it, after using this product should I take out the cooling water and clean the cooling cycle then pour new water or what?? Should I mix this product with water or coolant?

@leexgx 2 года назад

Usually just stays in the system until you replace the coolent after 3-5 years (depends if your using blue/green coolent or g12/g12+ witch is long life) last time I used it I didn't flush it (more then 5 years ago, water has been drained but it flushed 2 times in last 2 years) about to get some more because got bubbles now and heater core sometimes stops working until I get to 1800rpm (probably because the system was emptyed all of the k-seal is gone from the system) I thought k-seal was for external leaks so was looking for gasket sealant before having to change gasket or the car it self, but seams k-seal is goto it be really helpful if the sealent companys actually stated coolent compatibility like g12/g12+ witch is very common but liquid steel type products usually incompatible with (believe its fine with g11/g10/blue/green normal 3 year life coolent stuff) but k-seal is compatible with long life 5 year (g12/g12+/red/pinkish colour)

@Hinokami_TT 3 года назад

Do you have to drain your whole coolant? Or just a little bit to add the k seal?

@samhicks97 3 года назад

I'd opt to drain/siphon some coolant till you can get K-seal in. AND to top it off with distilled water or coolant, to promote fresh fluid mix with the sealer.

@quinnguy9484 7 лет назад

Thanks for the video. should I pour the K-seal directly into my coolant reservoir? The temperature in my car went to H last night...since then I've replaced my coolant twice today. I'm hoping K-seal will help. Should I pour this directly into my coolant resouvier? I've heard some people pour it directly into the radiator. Thanks in advance for the feedback.

@Darksyne 7 лет назад

It'll work better when you put it in the radiator but they say it also works if you put it in the reservoir.

@quinnguy9484 7 лет назад

Darksyne when you put it in your radiator did you have any coolant in there or had you already flushed it out?

@catfishsnagger3284 Год назад

Why would you do a coolant flush. K seal is supposed to stay in the system so it can continue to seal up any leaks should they form.

@Darksyne Год назад

You can but you don’t want left over stop leak cycling through your coolant system going through heat cycles and risk clogging tiny passages.

Takes a bit longer than half an hour for the stuff to fully kick in, and you're supposed to drive your car after to make sure it works and seals properly.

Pero eso esta bien echo???,yo creo que tienes que quitar la parte de refrigerante por la misma parte que vas a añadir y asi dejar el nivel correcto para que el tanque tenga expansión,y el bote de k-seal es para 21 litros de refrigerante es decir unos 11ml por litro de refrigerante,un motor de 4 cilindos lleva 4 litros,uno de 6 cilindros 6 litros y v8 8 litros,es decir si tu coche tiene 4 cilindros yo pondria 11ml por cilindro osea 11x4=44ml en el tanque de expansion.

@Darksyne 7 лет назад

Honda's subarus, nissans and Mitsubishi's dye their coolant blue because it's formulated differently than other cars. Bars leak won't fix leaks that stuff reacts with heat and only works on the headgasket but could clog up other parts. Trying to flush the unused stop leak has become a pain though.

@herbICG 7 лет назад

So, after all these months, what are your conclusions? Still keeping coolant form escaping the system? how long after pouring do you recommend flushing the rest of the sealant? And do you know if this sealant works with water in the radiator instead of coolant? thanks
