K-Seal Avaliações 530

Well nothing worse than that smell of leaking coolant in your car then the warning light and then the sodden mat in the drivers footwell. The cause was a leaking heater matrix on my Ford C Max. Top up and leaked out...garage said £1,000 to fix...what?, no way. After a trawl on the net I came across this product...well time to try I thought. Followed the instructions and waited. Engine on and wait to heat, at first there was leakage but once it reached working temperature it seemed to hold. Only 75 miles in and now no leaks...Happy days and thank you, all for £12.40...result. Update in a week.....

Ok so I haven't tried the K seal yet.
My 2006 Nisaan Xterra was overheating so I took it to Midas (they do all my major auto repairs) They did a compression test and it failed. 😪
Said it will be $4000 usd to repair. This is our only transportation for my family. So I'm praying this works. Stay tuned for the results. Wish me luck Colin!

My 2003 Volvo S60 was losing coolant and I was getting "Turn off engine" warnings. Whenever I turned on the A/C, the coolant would drain. I diagnosed online for what could cause this, and was seeing radiator replacements costing nearly $1,000. Fortunately for me, I came across K-Seal. So easy - I poured it into my half-full coolant reservoir and drove around for 30 minutes. Not only did my A/C run ice cold, but the coolant level remained full! Immediate results and a savings of $1,000! Based on many other reviews, I'm confident I'll get another 10,000 miles or more without any more coolant problems.

I will admit I was a little skeptical, but this product is amazing. I have a 2004 BMW 325ci that was leaking coolant. With it being almost 19 years old I didn't want to put a ton of money into figuring out why it was leaking coolant. I bought the K-Seal Ultimate, put it in about a month ago and haven't lost 1 ounce of coolant. And my car is running better than ever!

Dear KSeal
Good Afternoon! As a Commercial Pilot and Aerospace Engineer; actions speak louder then words. Recently, my 2009 Murano 3.5L AWD with 120K Miles; developed an internal Engine Coolant leak. Originally, using k&W, sealed the radiator. However; failed to repair the internal engine leak. After a two week waiting period; purchased Kseal multi purpose and followed specific instructions. Within minutes; the KSeal Performed as stated and sealed the internal leak. It has only been several days. However; the water level is being maintained. Great Job of saving me thousands in $$.
Regards

i have a ford focus 1.0 ecoboost (eco boom) engine , just done 83k , noticed on cold start up a misfire , just thought it needed a service and new plugs as it was over due , on inspection on cold start up misfired and a puff of white smoke , did a compression test and found out cylinder one was down on compression , with these ecoboost engines apparently they are not designed to be fixed and are a throw away engine ? so thought i would try K-seal ultimate bought it off ebay popped it in and wow fair play stopped the cold misfire and no loss of coolant and no white smoke , just done an other compression test and all cylinders now read the same , i am really impressed and thanks to k seal they have save me alot of£££££ , thank you i would recommend it to any one

I just replaced my water pump for the first time (meaning I’ve never done it before). For a couple days after I noticed some coolant on the ground after I parked for awhile. My hunch was that the gasket wasn’t sealing properly. Instead of taking it all apart and starting over, I added a bottle of K-Seal to the expansion tank. I drove for about 45 minutes and the leak was gone. It’s now been 3 days and no leak. This stuff works!

Hi Colin,
I am at GL16 7PB
I have a Transit camper (ex flareside) PJI 9345 2.5L
It has developed a heavy drip coolant leak from back end of engine head,so cannot see it but coolant starts appearing after engine idling 15/20 minutes from cold. No oil in leaking coolant, no water in oil, no white smoke, engine fine. Spotted it the other day with expansion tank low after a short (8 mile) journey. I presume it is a crack. Is this repairable with K-Seal and what chance of permanent success?

I drive a 2000 Chevy S10 with the 4.3 V6 vortec engine. Noticed a leak and sourced it to the upper bypass hose. Replaced it and noticed water pump weep hole was spraying driver side. Went to Advance Auto and bought the eight fluid ounce k-seal. Let the truck cool in the parking lot for an hour and then added it to the radiator after shaking it for 45 seconds. Added water to my radiator cranked it up and drove it lightly home 4 miles away. Parked it in the shade and let idle for 40 minutes with the defrost on heat full blast setting. Appeared not to have any water flow at this point. Truck was out of gas so drove it up the road and put a few bucks in it, then drove it up the road for a few miles. The temperature stayed at 208°. Drive it a few miles back home and parked it. Turning engine off pop the hood and notice a tiny spray hole coming from the water pump, driver side. At this point I don't know what else to do I tried to call the helpline and it is 11:15 p.m. on Saturday so they are not open. I have to work in the morning and it's a 20 mile drive. Got 2 gallons of water in the back, wish me luck.

My 2018 Ford Escape 2.0 T had the beginning symptoms of head gasket failure (actually it looks like a Ford design defect). Rough idle at cold start and white smoke from consuming radiator coolant. Dealer said 'long block replacement' required, an expensive repair. I used k-seal and the engine now idles properly and no more white smoke at startup. Not sure how long it will last but it is impressive that it worked. I really had nothing to lose trying k-seal since the repair costs are close to $10K CAD.

I just used K seal in my 2008 Buick because I had a radiator leak and blown head gasket. It worked great but now a month later, it is running hot. Is it possible I need a new thermostat or to have the radiator flushed or both. I hope I get this problem solved as I don't want to trade cars in this market.

Had a crack in an oil cooler on the turbo, only leaked when engine was cold. Kseal stopped the leak.

Rebuilt a 2019 F150 with 20k miles. After complete, lots of dripping along exhaust pipe led me to believe i had a head gasket leak. The radiator was dry so recovery personnel must have run truck without coolant to overheat the engine. Did my research along with testimonials. Installing K-seal solved all leaks. Cabin heat works normally. Just bought another bottle to fix a 12 jetta. Thoroughly comfortable with product

Ultimate head gasket repair worked 100%. Awful misfire and rattling investigated by garage - camera down showed rusty head gasket due to liquid ingress. Coolant levels down drastically after one drive. I put the k-seal in and followed the instructions and next morning, no misfire, driving fine. That was 3 weeks ago and all is still good!

After the mechanic failed to fix the leak after a $3000 repair job, we went online and saw the K-Seal review and demonstration on YOUTUBE.
We used the product and our car has been running fine ever since!
This product worked as claimed for us!
Grateful!

I had a 2005 Mercedes with a gushing coolant leak, thought a new water pump was needed. Mechanic advised to try KSeal. I didn't have much faith...
Bang! 30 minutes, done deal!
My 2014 Mercedes sprung a leak last week. Thankfully it did it in town as I had just finished an 1800 mile road trip.
I thought, "can it work again?" Poured KSeal in expansion tank, drove 30 minutes. Done Deal Again!

Just a recommendation, K-seal radiator sealant works brilliantly for motorcycles.
The result is great. I think it sealed pretty instantly. Of course I ran it until fan came on and off and checked levels repeatedly during about 6 hours of riding. If I go one a long tour, I think a dose of this (1/4 or 1/3 of a bottle) should be packed alongside JB weld for emergencies.

Couldn't be happier, especially as replacement is unobtainable and recore is expensive. £12 well spent. (I did actually also by the cheaper Wynns and Holts brand radiator sealant also, but I figured, K-seal only sell one product type, so they live and die buy it working properly)

The longer story is I noticed the garage topped up 200ml when she went for a carb tune up.

Then when straightening fins I notices a drop of bright green coolant, so I guessed I had a pin hole coolant leak. (maybe 1 drop per 5 minutes)

Scoured internet for testimonials, and while none had a glowing review from everyone, K-seal had the best overall ratio of recommendations and lack of complaints. I guessed people are 10 times more likely to complain than sing praise and it was one of the more expensive brands so I gave it a try.

K-seal is also one of few that actually mention motorcycles in the instructions and importantly can be poured direct to a cold radiator rather than expansion tank.

The particles in the bottle do settle, so shaking and pouring soon after is important.

I read a horror story about pouring a radiator sealant undiluted into the core (with fine passages) and it instantly blocking rather than repairing, so I syphoned off some coolant from the rad cap, mixed it well in a jar with the radiator sealant and poured as much back in as possible.
Will definitely buy again if needed and will recommend to anyone that'll listen.

Hi , I trusted K-Seal to my 2009 Lexus RX 350. I put the stuff in, but didn't really follow the direction right. But it WORKED. I did buy a new water pump to replace the old leaking one. But K-Seal is holding it together GREAT. It's buying me sometime until I can replace the old pump. Thanxs K-Seal.

Got to admit I never had much faith in stuff like this, figured it was a waste of money, a scam. I got a 2000 Toyota Camry that the head gasket blew or cracked head not sure which but started clearing my personal items out to take it to the junk yard. Buddy of mine come along and suggested K-Seal. I told him I wasn't going to spend $30 bucks for something that's not going to work. I was wrong! This stuff is awesome! I followed the directions and I'm flabbergasted! I been driving it for 2 months now and NO issues. However, I wonder how long it will last? So, the way I see it, if it lasts a few months, I got my $30 worth. Thanks K-Seal!!

I have a 2010 Ford Ranger pickup, 4.0L V6 with 68,000 miles. Had a recent overheat, poured coolant in, took care of it. Within a couple of days, took it in for an oil change. When I picked the truck up, they told me I was leaking oil and coolant - Blown Head Gasket. In the 10 minutes the truck sat waiting for me to pick it up, two 6 inch puddles of oil and coolant. Being a V6, highly recommended you replace both banks of the V6 even if only one blown. Would have been $3,300. Bought one can of K-Seal Ultimate, ran the engine 30 minutes. Not a Drop! It has been a month, I check under the truck and open the hood every time I take it out, hasn't lost an ounce of fluids! Trucks runs like dream! Amazing product. I bought some time - probably months / year or more - for me to figure out what next, and saved $3,000!
