you slowed the leak. Would have liked to see this run until the leak sealed or the water ran out

[@luffydragneel6035]

Awesome vid amigo For people using it, Don't pour a lot, little by little so it won't clog

Sooo cool. Thank you for the real time visual

[@billsauer3164]

I've used a couple raw eggs and about half cup of pepper in a few different squirting radiators. The egg cooks and scrambles in the hot antifreeze and the pepper will swell up to five times its size. Both the egg and pepper mix will coagulate wherever it's pissing from and seal up the leak. Smells like breakfast when you pop your radiator cap 😂😂 swear to god it works

[@miguelsantillan7697]

😂 good one 😅

[@flameofanor8252]

[@njgeneral3738]

Great video. Bars leak saved me when someone hit and run the front end of my car and the busted radiator wouldnt hold any coolant whatsoever. The big key is if you are gonna take the radiator out to weld it or try and find leaks and leak area is found, then just replace the doggone thing. You already did the hard work of removing it. Any vehicle with a good engine and good frame plus limited corrosion is worth working on. Used car prices are too much.

[@anteneupitra]

it wii bloc everything.aakaakakakaka

[@bigjimcountryboy]

I Have used it . I used it on a 2001Saturn SL2 to fix a bad head gasket , that was pissing out the side of the motor . My wife drove the car for another 60K miles with out adding any more coolant !

[@commonsenseisdeadin2024]

back passenger corner? I had 2 SL1s that both leaked coolant exterior of the head gasket on back passenger corner and 1 had a external oil leak from the head gasket in between cyl 3 and 4 but compression was fine, so never touched it. I was surprised to see the oil leak coming from the head gasket, no idea what caused it, obviously the oil is not pressurized when bleeding back into the crank case. Saturns were beasts, Slow as all hell but if I remember right GM literally stopped making the proprietary engines because it was better than the 2.2/2.4..... Of course they don't replace the 2.2/2.4s with the 1.9 SOHC/DOHC, they stop making the 1.9s. Couldn't have used the timing system GM? No what did those motors run for 15 years? Never got the timing chain issue fixed 😁

[@tjmccay166]

Definitely works. Thanks 😊

[@aaronmenchinger]

I commented on your video from 4 years ago and immediately following the comment, I saw this video haha. Much better. I used this for a small head gasket leak I believe. It's a turbocharged 4cyl Cobalt SS and it worked awesome..... Until I got comfortable that it worked after a few weeks and got into boost. Later that day and following, symptoms gradually came back and nothing seems to work after. So take from it what you will but if I had a naturally aspirated engine I would like to think it would have been semi permanent at least haha

[@tonymemory2279]

On a blown head gasket you have to use pure 100% sodium water glass not any of the store products. Don't use Blue devil either. It's only 30% sodium water glass and blue food coloring.

[@oldguy2082]

Block sealants are really only a temporary repair, the only real fix is to fix the engine. Damage can result over the long term; a block sealant, i.e., Blue Devil, K W Block seal, etc may work in the short term and as such, is okay. But, they can also clog heater cores cause water pump problems etc. FYI -- I used KW Block seal (in the copper coloured can-- )on customers vehicle's for over 40+ years with good results. The trick with KW Block seal or any related product is to follow the instructions to the letter. Don't try and rush or shortcut the process; success or failure depends upon patience and effort.

[@jbd4365]

Yeah I'd never use it on a quality car but I think for a lot of us our old cars aren't even worth repairing something like the head gasket

[@jzwillows]

These products should have passed ASTM 6107 which is a test to ensure they work and cause no damage. In addition some, like the Bars tablets, are OEM (tablets have been used for 30 years).

[@MichaelLangell]

Are you just talking about the product that he’s using in the video or in general? Over 100,000 miles ago I used a walnut shell pellet inside of my engine on my Chevy Tahoe and it has not leaked at all sense.I’m sure it depends on the situation and damage but it’s works great for mine.

[@kevingray7917]

I've used it for a 99 Ford f250 super duty with the 6.8 V10 gasser. It lasted a fairly long time, about 8 months until I pulled a heavy load. Honestly I wasn't to surprised when it stopped working under the extra exertion from pulling 10k. That's a bit much to ask of anything meant to be a temp fix and for a cost of under $10. Had I not pulled a heavy load, I have no doubt it would still be working.

[@robertfrayer6711]

Ya dont think the gunk it left in your engine and around the thermostat contributed to that?

[@SoyMonicaedith]

So they are selling me a car with a radiator leak I think this will help..... My questions is car is stopped do I just pour this inside do I add water? Then start car?

[@sebastianfierro7423]

Great video

[@E85_STI]

This is a great demo and of course the coolant system is under pressure and heat but hopefully no one is using this as a permanent fix. I’ve seen some cars with a spare tire for months on end and that’s not good especially when it’s the front tire.

[@wmsstuff271]

I asume you mean one of those anemic wee skinny space saver wheels. My spare wheel is a full sized number with a brand new premium tyre on it. It could be uses for years if needed.

I had a 2009 Pontiac Vibe with about 227k on the clock. The car still ran like the day I bought it.but I allowed a roommate to drive it to work and he ran the coolant dry. This in turned ruined my headgasket. I bought the bars to try and repair it, but unfortunately it threw a rod on me. Shockingly the crazy car still ran even with a hole in the block. but not very well.

[@jeffreygeorge219]

Bro if your room mate drove it to work and it ran dry, wasnt his fault, you should of did some maintenance on the car. You think a few miles did this. That iss like me borrowing a car, driving to work and the engine blows because there is no oil in car. Not my fault.

Leave it for 24 hours and then drain/flush out anything solid or hasn't cured before putting it back in my vehicle.

No. Modern car HVAC systems are a whole other ballgame. Besides, the orifices in the condenser, are super small. Any blockage there, will destroy the compressor. You’ll probably need a whole new system after the compressor bites the dust.
