Thanks man. 2000 4runner with head gasket issue. Going to pick that up and try it. I'll post results tomorrow👍

Worked for me today. My issue was exhaust into the coolant system. I had no coolant into the oil. I introduced the Kseal into my top radiator hose 2/3 and 1/3 top of radiator. I also bled the thermostat housing which is important

I've used this a few times it's always work for me you got to catch it right in the beginning. I recently noticed my ford focus occasionally had a little bit of the white smoke so I put a thing of K-seal in as more of a preventative as these are notorious for fluid intrusion into the cylinders. So far so good but when it starts to get really cold below zero it will tell me how it did this time

It worked on my mother's 1996 bmw 520i e34. Symptoms: white sweet smoke, not extreme but noticiable . She was lucky because it overheated once and the head was not deformed. I guess it was a small leak in the head gasket. I watched this video before try it, so thank you for sharing your experience.

i use it all the time....like it

Well I'm going to try it on a Northstar engine and see what happens. Anyone who is a mechanic knows how they are. So we'll see. Thanks for making the video

worked for me on my 2002 mercury mountaineer

My 05 corvette is loosing antifreeze and my oil is fine and I'm not over heating but i changed my thermostat and reservoir cap and I did see some white smoke at start but not as bad as in your video so do you think kseal can help mine? Thanks in advance

I used k seal on a 2001 infiniti qx4 3.5L about a month ago. 249K miles on it, only added 300 miles since the treatment, good so far.

Does it still work if you don't un-plug leaking spark plug / corresponding fuel injector?

Thanks for the video Jabo. I just tried K-Seal in my Nissan Xtrail. Fingers crossed. Mine wasn’t near as bad as yours so we will see how this goes. Will keep everyone updated. 😃👍

My car was using coolant on long trips, and there was bubbles on the radiator, I didn’t have the money to change the head gasket rn soo I just found out about these sealer’s and bought the K seal, drained and clean the whole system put new coolant on it and the k seal, let it idle for 30 minutes, then let it cool for 3 hours, again idle for 30 minutes and cool for the rest of the night, about 10 hours, there’s no bubbles, doesn’t smell like coolant getting burned and doesn’t smell like gasoline on the reservoir.

I used K-Seal twice on my 06 GMC Envoy Denali, but it didn't hold. The coolant is leaking, but not into the oil and there's no white smoke - but it only takes 60 miles of driving and it starts to overheat. I'll need to get a mechanic to do the head gasket repair.

Was there antifreeze in the system when you added the K seal?

Amazing

Going to try this product in my 02 ford ranger but it's very cold outside please wish me luck

My 2005 honda accord has white smoke when i start it but it goes away after about a minute. But it has some rough starts so going to try this stuff.

I'm a mom of 3, in Chicago. I have a 2011 Jeep Wrangler Rubicon. I had #6 & #4 cylinder misfires. Turned out, coolant present when the 6 & 4 spark plugs were pulled out.. I was told my Head Gasket had a leak. No smoke, no overheating etc. Nothing, just coolant disappearing after about 2 or 3 wks, then all of the sudden gone overnight. Only one time did it "shake" on first start of the day. All other 1st starts are hesitant, and then fine after about 15-20 seconds. 3 mechanics said HG are not "fixed" or "replaced" and that the entire engines have to be replaced with having a "leak". I'm a woman, but even I know that's total BS!!! The stealerships in Illinois are also horrible crooks and liars! Even stole parts off my special edition Jeep! Cannot be trusted. We're a low-income family and I just bought a can of K-Seal today. I'm going to "try" to fix this myself after I research some more. If there's anybody in Illinois that is familiar with this stuff and head gasket leaks, I'd appreciate a friend RN, and some info/help. Thanks everybody. And thanks for this post Jabo The Mechanic.

Where I can get this k seal in South Africa

For a 4 cylinder 1.9 liter engine, do I need to pour the whole bottle? Or should I just do half?

Bro how long did it keeps up

Hi. Do you need to get an oil change and coolant flush after using K-Seal? Thanks.

yeah K seal been around for a minute

Do I have to flush the old antifreeze mixed with K-Seal after the leaks sealed ? If so how soon

Can i pour it into the reservoir instead of radiator?

Do NOT put pure k seal into the radiator put the k seal in water or it will clog the radiator

Blue Devil didn't work for me. K Seal is great!

Do you have to remove the thermostat?

Jay is cute as hell to me

Hi all! My 2004 4runner has been misfiring on cylinder #2. After new plugs/engine coils, replced fuel injector, the check engine light came back. No white smoke, no over heating, just shaking on cold start, then good. My mechanic friend said 99% sure its cracked gasket. I bought Kseal ultimate for gasket, poured it into the reservoir in the store parking lot, drove around for 20 mins, then parked for the night. Next morning, no shaking at startup. By lunch time, the check engine light cleared itself. 2 weeks later(Yesterday morning) it started shaking again on start up & check engine light on again. I checked the code, still saying misfire on #2. Did i not use the Kseal correctly the 1st time? Does anyone have any suggestions? Im a single mom who LOVES her 4runner and Cannot afford a new car right now! Especially here in So cal!! 😢

I have coolant bubbling in my reservoir and the reservoir tank fills to the top after a short drive plus the temperature gauge spikes and returns to normal as soon as I accelerate. I used k seal . Removed top rad hose and poured it into cold engine then took car for a 15 minutes drive and left it run idle after the drive for 10minutes the k seal did absolutely nothing to fix the problem.

In your experience, how long has the seal held up?

Hi mate, just wondering for how long does it last the repair??? Do you have any idea? I'm in Australia and I don't know if buying a k-seal bottle or the bar's leaks head gasket fix 1 step (branded as rislone in Australia). Kseal is $25 and the Rislone bottle is like $90 here in Sydney, big difference in price but I see many people using the kseal, thanks for your video!!!

Was is k seal ultimate?

Cannot beleive that someone can smoke this s...

I’m only one minute in and I hope he’s only joking lol. Don’t put any sealant in your car unless it’s a junker and you don’t care 🤷🏽‍♂️

Please stop selling snake oil fixes. I know you get paid good from the sealer company. There is not even one dollar worth of value in this product.
