I have used K-Seal on 2 Toyota's and 1 Saturn radiator leak and it worked each time and still holding strong. I have the radiators on hand but since the K-Seal worked I have left them alone! Never tried head gasket in a bottle though!

@TheGhungFu 6 месяцев назад

Putting the radiator cap on and letting the cooling system come up to pressure may work. That will help force the product into the head gasket. Pretty sure none of these products will work without several cycles under cooling system pressure. No way for the stuff to get into the head gasket while the cylinders are under higher pressure.

@stopher1971 5 месяцев назад

That is exactly right, common sense, very hard to find nowadays

@stopher1971 5 месяцев назад

K-seal pour-n-go is another rockstar, put it in a 4Runner Straight into the coolant and let it run through the whole system, heater, core and all I think it was less than three minutes. Everything was fixed the hole in the radiator and the head gasket. This is just idling at temperature. This was six months and 4500 miles ago You’d never know there was anything wrong with it

K seal sorted out the leak in my head gasket on a Primera P11 years ago. I drove it another 30,000 miles or so and it was still running when I sold it. That was a 2.0L and about 170bph. On my H6 Legacy Spec B though (model year 2008) it didn't work. Worked initally but within about 200 miles the plug would fail! Ended up selling it to them traders that pay jack-all...

@lamka02sk 6 месяцев назад

We had a small leak in our Nissan Xtrail in the past and used sealant from Liqui Moly with some glittery stuff inside of it. I can't find it online right now, but I can tell you how it worked. So maybe, just maybe, this stuff works the same. At first, coolant was still leaking even after recommended 30 minutes of driving, so we just kept adding distilled water and after maybe 200-300 kilometers, it stopped leaking and lasted about 2 years. After those 2 years, it started leaking a little bit again and we repeated the same process and again, after 200-300 kilometers, it sealed everything up.

@ibcrypto6139 4 месяца назад

I think no matter which product. If your getting combustion gas in cooling system - find the cylinder and remove the plug and heat up/cool down 4-5 times then let cure 24 hours. Most of the products include theses steps under advanced applications.

In 1958 the USS Nautilus had a leaking condenser onboard - it was critical to repair the leak as the ship was about to make the famous transit under water and across the North Pole. The Captain had the crew scour around Seattle for Stop Leak (now Bars Leak), a radiator leak stopper for cooling systems. 140 quarts were found and added; the system sealed and the Nautilus made its historic voyage without any further problem. But, a bit different from a Subaru head gasket leak...

bars leak is the only one ive used in a pinch when i had a old 04 legacy, it held up after use for about 2 years before it gave out and started to overheat again. i didnt care much to repair the car since at the time i lived in ny and it was practically rusted through, cant complain for it lasting just a bit longer since it was gonna go out whether the chassis or motor gave out first

I used the quart sized blue devil on an 07 gmc 5.3L that was using over a half gallon of coolant every week. I removed the thermostat, crimped off the heater hoses and poured the blue devil into the engine via the upper radiator hose. Topped off the system with water and ran at idle for an hour. When cooled i put the system back together with new coolant. It took two long (20 mile) drives to get it to stop using coolant. So far I've put 500 miles on it, and the coolant has stayed at the same level. Fingers crossed i get a year or more out of it.

@julianfisher6134 6 месяцев назад

Well you're looking for a magic fix in a bottle, over the pond here in the Uk try Steel Seal. An engineer gave me this tip years ago & I swear by it ! Out of all the times i've used it ,it has only failed once on a seriously overheated head gasket. About ten years ago I had a hair line crack in my cylinder head by No.1 injector, tried Steel seal and it fixed it.Have never had the problem reoccur. It's made here in the UK but hope you give it a try if it's available over there ? Really appreciate your video's & advise, please keep them coming. Julian.

Try Sodium Silicate and water mix aka water glass i bet its gone after that as they dont sell it anymore in stores. Ive used it before on a 96 grand prix with a 3.1 and my sister drove it for about 10 years. She sold the car and i used to see it around. Also you have to put the cap on after you get most of the air to stop then drive it around for a day, check it the next day and it theres no more bubbles, then drain the system completely and the sit with the hoses off to let and circulate through the system over night. They add 50/50 mix bleed and all should be well.

@feeneysauto3432 5 месяцев назад

I actually seen that blue devil stuff seal a head gasket on a 3.4 impala that had a misfire from the head gasket being bad. It was a customer that didnt want to pay to fix it and I told him if you use that crap its gonna cost you more money because that stuff gets everywhere in the system. When he brought it back a week later i took the heads off and you could see where the sealer did seal where the gasket failed there was all this hard white stuff around it so the sealer must cure when it gets to exhaust gasses. The sealer plugged up the water jackets around that cylinder so it obviously got hot and made the sealer fail lol.

@spencercpu1983 5 месяцев назад

It takes a while to fully seal leaks in radiator anyways I used 2 or 3 bottles plastic at top is cracked. Finally leaks stopped but took a long time just drove it around while keeping coolant level topped up. Total time was over a 4 week time frame first it would stop leaks interemintally then when not completely full then when topped off it would squirter coolant but now has stopped for about a week, I imagine that head gasket may be even more difficult to seal but maybe it would eventually help but I've only used the standard k seal for radiator leak at top plastic housing area horizontal Crack in middle I hope I didn't add too much and won't add any more because I am worried about clogging issues or water pump seizing but for now all good

In the past couple years I have to fill oil approximately 3/4 quart per 3000 miles. Should I have it repair now which is quite expensive or should I just wait for head gasket to fail and do both at the same time?

@attygarland6909 5 месяцев назад

Blue Devil, the 'Pour and Go" formulation failed my blown head gasket. Problem w. that product (and possibly K-Seal as well?) is that it is only sodium silicate/liquid glass w/o anything else added to it to increase its sealing properties. I'm about to try the "Professional" blown head gasket product made by Bar's Leak to see if it in fact works. It contains carbon fibers (think "Kevlar") in addition to the usual sodium silicate in order to quickly work on sealing up the leak(s) w/i 15 minutes or so of running, vs. the B.D.-type products that require up to almost an hour of running time to start working.

@bigc9464 Месяц назад

I never used combustion leak fluid till the last couple years. But I can find head gasket issues through this very method months, if not years before it's truly a problem. I bought my v10 excursion 3.5 years ago with a weak head gasket, drove it for 2 years before I was seriously suspicious. Leak check fluid never picked up CO or CO2 but a power brake would make it volcano out of the degassing bottle. It went over a year from that date before any leak check fluid would pick it up. Before anyone says "it's the fluid" I had universal blue point and the gasoline specific from the parts store.

Steel seal is a better alternative then k seal when it comes to head gasket leaks from my experience. for the folks who want a cheap solution to a major problem just have to drain all coolant fill with regular water/ steel seal and let run for 1 hour with heat on max; turn off let sit overnight then check results following day. Results vary.

I've taken an engine apart that had that stuff in it, and you could see how it was "trying" to work. It had copper deposits around the leaking areas, but wasn't good enough to seal. IMO, that stuff is a waste of time and money and gets that crap all through the cooling system, engine ports, hoses, water pump, heater coil and all. BTW, same with the heater coil leaks. If it is a last attempt and you are not going to pull the engine apart anyway, I guess you have nothing to lose if you are going to junk the car.

Have you verified combustible gas in cooling system with chemical test?

@kitfisto1827 16 дней назад

You most likely have a situation where the leak requires multiple uses regardless of brand. The Bars has the benefit of sealing up the last little bit of leak that the K-Seal started to fill, but didn't quite get all of it. Reverse the brands and you probably have the same outcome.

@friedryce 16 дней назад

@@kitfisto1827 Could be, but more likely I think it's due to the fact that Bar's seals up to 0.015mm vs K-Seal Ultimate's 0.010mm width. I can even see copper flakes where the K-Seal just ended up leaking through whereas the Bar's pretty much immediately stopped the leak when the coolant circulated (maybe also helped by the fact that it's a lot thicker). Believe me, I wasn't expecting the Bar's to do jack s----, whenever I see buzz words like "cabron fiber reinforced" and all that non-sense mumbojumbo, I am super skeptical--like how is it going to help fill the hole? Are the carbon strands pre-impregnated with resin? It doesn't make sense to me and I've worked with carbon fiber professionally. But it definitely worked.
