K-Seal Avaliações 530

I just try it on my water pump work good so far it stop the leak hopefully it last long till I can save up to fix it! on my 2006 pt cruiser.

My used 2013 Dodge Journey has slowly leaked radiator fluid for some time. One day while driving to work the radiator gave out. I had a new radiator installed, figuring this would take care of the leak. When I saw that fluid was still leaking, and my check engine light came on, I took the vehicle to a local garage for a diagnostic, along with a scheduled oil change. I was informed that radiator fluid was leaking into cylinders 2 and 4 (this is a 6 cylinder vehicle). I have the estimate in my hand as I type this, so this estimate is in no way embellished. They want $5,163.42 to fix this problem. Since that is about what I paid for the vehicle, I told the mechanic I will just drive the vehicle until it dies.

When I got home, I looked online to see if there are any products available that may extend the life of my vehicle. To my surprise, there are products that can seal small leaks like the one I have. I decided to go with K-Seal, based on the reviews compared to other sealers. I bought my $15 bottle, poured it into the reservoir tank, and took it out for a drive. This was back in June. I am due for an oil change in 400 miles, so I have driven close to 2,600 miles, and not one drop of antifreeze has leaked. My check engine light has also disappeared. I can't thank K-Seal enough for saving me over $5,000 in auto repairs.

Called K-Seal first to discuss the symptoms and nature of a cracked head pushing exhaust gasses out and the confirmed this product would help as it was not the coolant leaking out within the engine. They could have just sold to me regardless but instead took the time to discuss the problem and the solution forward 10/10 for honesty and professionalism

I have a 2009 BMW X5 3.0 and it initially worked for two weeks. I was sitting in the parking lot of the supermarket and I noticed the engine bay smoking! I bought two bottles of coolant and another k seal. No go this time. I have to get it towed 🤬

Be careful with this product initially it will work. But slowly this makes your car vulnerable. This product blown my head gasket for Ford fiesta and I end up with huge loss fixing the head gasket it’s costing me now 800£ to replace head gasket.

I was really hopeful that this would work I have a small head gasket leak and with the reviews I was seeing I knew it would work but to my disappointment it wasn’t helpful for me. I’m sure in some cases it might work great as per the other reviews but for me unfortunately it just didn’t happen.

Had a gasket leak on the sprinter popped a bottle in her and BOOM 4 minutes completely sealed then drove 380 miles and not lost a drop - well impressive

I have a coolant leak somewhere on my insignia I think it's c9ming from a pipe or radiator would k seal solve the problem?

Dit spul doet gewoon waar het voor bedoeld is.
Opel station uit 2009 begint opeens veel koelvloeistof te gebruiken. Ik was echt sceptisch maar zat niet op een 500-1000 euro koppakking/radiator reparatie te wachten.
1,5 flesje erin gedaan en gewoon werkelijk geen lekkages meer (vloeistof al maanden op peil weer).
Lekkages waren niet visueel dus ik vermoed een koppakking...

Money back guarantee yeah right I try two bottles nothing changed at all had yellow black tag on bottle said money back guarantee send them pictures what I paid for it they just left me hanging didn't back the there money back guarantee at all that's joke people don't believe the yellow black tag on bottle that mean nothing to them at all its just way get your money lot easyer they claim fake lie get people believe in junk

Bought a 97 Nissan 4×4... coolant would just disappear not in oil or coming out exhaust... so I tried k seal...it absolutely resolved the problem within 5 minutes... u can't go wrong with this product!

Vauxhall mokka 1.6 petrol
Had the car for 4 years started using coolant smell of sweet antifreeze when car was used brown gunge in coolant expansion tank and loads of water droplets on internal top surface of coolant tank
Feared the worst last used k seal one month down the line gunge gone droplets gone hasn't used a drop of coolant and no smell of antifreeze
Miracle in a bottle I'd say

I bought K-Seal Ultimate about two weeks ago. After extensive familiarization with my vehicles symptoms. I had among other issues come to my comprehension why I would have the best chance of repair using the K-Seal formula that has to do with the distinctly different materials the product uses to close leaks. In my case my oil had become contaminated with coolant. I found THAT this particular K-Seal product allows you to completely ignore the fact that most all the other products with top notch reviews use glass particles, or ceramic to stop the leak. I learned that my vehicles likely problem would have made the mainstreams most popular formulas and process the mainstreams uses that are made up of GLASS fibers (ceramic) that fill in the leak and my understanding is that the type of leak I have will likely not work with that formula. I needed one that stops the leak using a formula without the glass ceramic fibers. I must use an entirely different formula and even then it will be complete "luck of the draw'. The kind and type of leak I have in the engine does not stand a very good chance at sealing using the glass fiber particles. K-SEAL Ultimate Head Gasket Repair has a does have a chance. Hopefully my No Crank No Start issue will be solved this morning and I will finally be ready to use the K-Seal. My vehicle had several problems develop that compounded to to cause my vehicle to become unusable that I had to fix before addressing the leak issue. In Short this review is only part#1. Stay tuned for my part#2 REVIEW. Now to go out and see if my vehicle will finally start so I can use the K-Seal Ultimate. Wish me luck.

Had a small antifreeze leak in cab of 2015 nissan frontier that appears to be from the heater core. Put one bottle into my radiator and drove truck for over 30 miles to see if it'd set. Leak seemed to stop for couple of days but now has returned as an bigger leak.

I have a 2015 Ford Fusion SE Ecoboost with turbocharger, 92k mi.
I have a very long story over past 3 months of check engine light and #4 cylinder misfire issue that couldn't be resolved. Multiple trips to the shop & diagnoses, $2k spent on new turbocharger, and check engine light still coming on. Bottom line mechanic says engine must be replaced--blown head gasket and/or cracked head. Said $9k to replace engine!!
In desperation I did a lot of research on head gasket sealers, bought K-Seal, put it in yesterday, idled it 25 minutes.
Drove it today. Check engine light went away!! Car runs very smoothly. I will write back in 6 months and let you know how it's going! Thanks!!

May 9, 2024 Update: I haven't been able to start the car for a week. Tried various things, towed to trusted garage and verdict is I need a new engine. Now just trying to get rid of it. I'm not sure if the K-Seal failed outright, or if the existing damage was too much for K-Seal's long-term "reach". At any rate, it was worth a shot.

I was absolutely amazed. When the guy at O'Reilly's told me to put the bars leak back and get k seal I was hesitant but I'm glad I did. I didn't know where the leak was but I hadn't looked yet either. When I spotted the leak after pouring it in I said well that was a waste of money. It was pouring out a crack in the bottom of the radiator but to my surprise it actually sealed it. I wish I could post the videos I took

This stuff is amazing!!!! I had a small leak in my radiator and it wouldn’t hold coolant I bought this bottle of kseal and in like 5 min the leak was sealed!!! I’ve been driving a lot for 2 days and my coolant is still full and working great!!! This stuff is a true blessing I’m so thankful!!!!

K seal works. Give it a go, you'll be pleased that you did. I tried it with my mechanic's approval. He said it'll work or it won't but it won't clog up anything. Guess what, it worked. My mechanic uses it all the time, with the customer's approval. Can't praise k seal enough.

I have an old 1977 Aussie Holden. It developed a small leak from the head gasket. My mechanic diagnosed blown head gasket. It was forming only droplets of water but it was consistent droplets developing one after another. I read reviews on multiple products, and also recalled hearing positive comments in the past on Kseal. After convincing myself that the product would not damage anything I decided to try it prior to spending significant money on a head gasket replacement. I added as per the instructions and drove for about 30 mins. Checked still a minor droplet developing. Drove for another 15 minutes,pleased to say fixed. I have waited 6 odd months prior to writing this review in case the results were short lived. However 6 months on, not leaks whatsoever. The reason I have taken the time to write the review is to share with others my successful experience. I am extremely happy and happy to recommend KSeal for like issues.
