How to use K-Seal URGENT Watch before you damage your Engine, radiator leak repair fix correctly 

Very good advice on diluting the product before pouring in radiator and also not using too much! A common sense procedure, so easy to overlook and can cause huge problem.!

“This is if you have a slightly older car” 10 sec later Here’s my 90 year old car

Excellent!!!! Had a small leak in my 85 brat heater core... Mixed 1/2 in a bottle, drained some coolant, and poured it in.. After mixing completely off course.... Great advice thank you....I would probably recommend this technique for any style of vehicle.

In 2018 I had a 2006 Chrysler PT Cruiser with a bad head gasket and a coolant leak and I poured an 8 oz bottle of K seal directly into the radiator while it was cool and followed the directions on the bottle. It fixed the problem and I still have that car for an additional 3 years before it just died altogether from other issues.

it works good i tried it drove home from the mechanic shop saved me 1000 dollars...very amazing stuff stops smoke you can drive it good...stuff works cost like 40us

Thanks. That's is really a good advice.

Bro of course you wouldnt want to ruin the engine on that piece of history 😂

Nice ols car mate. Good video thankyou. 👍

K-Seal really works folks. I own a 94 Toyota Celica with over 335,000 miles on it and it smoked like a freight train and after i used a 1/2 bottle of K-Seal and drove it for 15 minutes..... NO SMOKE AT ALL! I SWEAR BY THIS STUFF. IT REALLY WORKS!

Nice car! Good tip!

how long do u have to wait if u do it early morning when engine is cold cold n can u put in overflow tank when engine cold n is it best to just idle n warm up or best to drive let warm up n continue driving just wondering how long takes to actually get through cooling system if added to overflow tank and if it continues to flow through system while driving or do i have to shut car off n cool n start up and wait for warm up again n drive confused thanks

K seal worked for me on a very bad 97 econoline v6, and a less bad 2005 4runner v6.

Ive used K seal many times, i like it, even as a leak preventative. I wouldnt use it in your car ,its not a pressurized system, this product works with pressure to seal the leak. I dont think theres any prob with leaving excess K seal in the system for the next leak

Juat poured 2 bottle directly in my "slightly older" car and then saw your video. to me old is 2001 Galant and 1934??? Seriously? 😂

Hi sir can I use this k-seal ultimate in time reserve tunk on my vehicale.

Rather than drain the radiator, is it not possible to add the K- seal with the engine on tick over? My Alvis has a very good flow at the top of the rad even on tick over.

My mechanic reckons my cylinder head is sound and believes the very, very slow ingress of water to the sump is via the oil galley do you reckon this stuff would seal it. (2005 VW 2.5 diesel)

Feel free to bring your car here and leave it! :) Very nice looker and must be a joy to drive! Found video as my 1974 Ford F600's radiator still has a leak after soldering the tank back up. (Not nearly so nice looking as your car!) Going to try some of this KSeal before throwing in the towel for either a recore or $800+ NOS radiator... if I can find one!

I poured mine in after shaking it and it still works 6 months later

I have a 1998 chevy Malibu and my coolant wont even stay in the tank...its coming out the bottom like piss....would this work for my beater?

J B Weld is good too for visible leaks. Empty radiator, remove all rust and foreign material, seal all the holes, allow 24 hrs to cure

Dang! Look at all that room around the engine!

Question, I don't have any freezing my car at the moment. I have water in it because I have a leak. Can this be mixed with water?? Once I fix the leak, then I will put antifreeze back in it...

I have a 2005 Jaguar XJ8 4.2 Does not have an expansion tank. Car does let off white smoke indicating possible gasket issue. Should I dilute or pour direct?

It sound important but where do i purchase this

Make sense 👌

Hi, interesting process. I'm also thinking that doing it this way on a modern engine, as I believe (despite what the bottle says) that it will clog internally. Maybe even needing to flush the system through after the process to prevent material staying in the coolant after the material has sealed.

Does the HD work on Detroit 60 series???

My leak is on my heater matrix and it's a complete removal of dashboard to get to it. I have no time to do it and it's way too expensive to go to a garage. Any chance it could seal that?

That's an old metal radiator with copper tubes in it you oughta be able to solder that tank I used to working a radiator shop back when they used to have them and we would take the radiator apart and ride them out clean them out and then put the upper tank back on there and we fixed hose and we did it all with solder just an idea probably be cheaper than k-seal

I have water in my radiator atm. Should I fill with k seal, flush and fill with coolant in a few days. Or should I flush now, put new coolant in with k seal?

Just Harry Johnson So was this the first time you yourself have used this product? What I'm really asking is, do you have experience with this and how highly do you recommend this product? Thx in advance.

My antifreeze is leaking into my gasket.. will this seal it off if I add it to my antifreeze

Can you dilute the K Seal with water other than coolant?

I don’t understand how the k seal directions are supposed to work. It says you shouldn’t add it to the radiator but instead add it to the expansion tank. If you do that, the k seal will eventually end up on the top of the radiator anyway. Just and update for everyone. I added it to the radiator and it’s fine. I just mixed it with a lot of coolant before adding it. I only used 1/3 of the k seal too. It sealed a head leak and I no longer lose coolant or have a misfire. I have also been draining the radiator fluid every weekend to remove any excess k seal.

Thanks for the video. Wish I would of watched this a month ago... Diluting the k seal before it goes in sounds like it should be on the back of the bottle. Well both of your tips should. If you don't need the whole thing don't use it right away. To bad my little camry just got one of the bigger bottle added to it tonight... completely... Guess I will be flushing it out tomorrow after it does its job fixing the head gasket. No need for it to hang out any longer. Thanks again

What if there is nothing in the radiator

Bro said slightly older and than shows the first fucking car invented

Any update if how long the k seal last??

Hi all, I need to use this on my brothers car. I was told I would need fresh engine oil to stand a chance of it working. Is this true?

I know this is an old video, but im a simple bloke, and theres so many vids telling different things, yours is first ive seen about diluting it. Ive even watched the k seal official promo add and they say just chuck the lot in, hot or cold engine. Edit, just read the instructions on the bottle, everything youve told me to do in this video is wrong for my car!!!!

You should have used 50/50 Coolant bought at an Auto Supply... But if water works? What the heck...

Will this fix a water pump leaking coolant?

do your heater has to be on or not?!!!

MY BROTHER IN CHRIST THAT CAR DESERVES BETTER THAN SEALER

Damm i poured all the kseal into a water bottle with water filling it to the top but i just saw your video where you poured half damm it didnt tell me that in the instructions

Mixed with water,

I wouldnt be using K Seal in an engine like this. That radiator needs rebuilding. I used a company called Northern Radiators.

Fuck i put the whole bottle didn't even know it had those peel off instructions

Jesus, can y

What in the world are you working on? I couldn’t show us how it works on an average car??

Would I mix this the same way for a head gasket

“Unpressurized system” ??

You need a new radiator Dude

load of crap paid 13.99 for it. aweek later leaking again. bought radweld 5.99 so much better been driving leak free for 8 weeks now.

It dont say pre mix this crap

Slightly older car? Blimey old chap you don't say

Says slightly older car then brings out an almost 100 year old car...

1934 car. I wouldn't put k seal in a classic car.🤣🤣🤣🤣🤣🤣🤣🤣

Be careful when you use this KSeal shit. I put this stuff in my van's cooling system and it hasn't run since February of 2020. Where do I begin? I began to have intermittent stalling problems. Everything that looked like either a fuel blockage or lack of spark etc. I even bought a new $93.00 MAP sensor and STILL the problem was there. So now my engine is essentially running poorly. However I maybe used too much by accident. The head gaskets are a main point of failure if your leaks are else where. The cooling jackets are rather wide BUT the head gasket has small slits that restrict the flow of coolant to prevent over cooling. KSeal CAN stick to your head gasket and slowly DAMAGE your head gasket!!!! So if you use KSeal my STRONG recommendation is use the absolute LEAST amount of it as possible and when your leaks are sealed CHANGE YOUR COOLANT!!! Or take it to a respectable mechanic within a month. Don't make the same mistake I did!!!
