Just a small comment about the bubbles on your radiator. Loosen the radiator cap to equalize the air pressure. Try that technique on another crack if it should happen again and I bet you there won't be any bubbles. UNLESS ... It's kind of the same effect as holding spray paint can 3 inches away from what you're trying to paint( bad idea)because you're going to get runs/bubbles👍 So hold can farther away from radiator so the spray doesn't bulk up so readily. And for heaven's Sake clean that surface extremely well beforehand. Okay so I guess it was more than comment LOL. Thanks for the tip and using your car as a guinea pig so I didn't have to 😎

You have to spray various coats. You spray once, then again, then again till you build a nice thick seal. Do not over spray or you will cause water drops or bubbles.

[@miguelperaza6615]

Don't be afraid to shake can for 5 whole minutes ! Then it will work ! 💪

[@joecox9958]

OK thanks for JRobling's update: Flex Seal doesn't work!

[@lovetrump1088]

This product will never stand up to the pressure and heat over time. This Flex Seal product is "not" intended for pressurized systems or heat applications like a Car Radiator. Because it says for Leaks...does not mean it works on a Pressurized Water cooling system.

[@snodgrassgerald2352]

yeah i have a tiny pin hole on the the top plastic connector hose. i'm use JB water weld

[@joecox9958]

that's what I think also

[@DebSant8944]

Directions say to shake can WELL B4 USE! No offense, but 1-2 quick shakes was likely why didn't dispense correctly. Awesome idea for fixing the pos Apple cords that ALWAYS break on EVERYBODY! Tyvm for the radiator video. Husband needs new radiator & I thought about seeing FlexSeal ad on tv & told him to try it but he's still lol at me! Beats spending $100+ labor!

[@joecox9958]

not only temp there is a pressure, so I doubt whether it works. hopefully there is update or other can also confirm it

[@mahrez5244]

My man thank you for sharing this

[@victorian.mccormick6298]

You are such a genius!

[@jsmith3964]

Fiberglass layer pad and seal 4 times still holding

[@chur1503]

Start your car and see if it still leaks from beginning to the end ?

[@ChrisHarbison]

FLEX SEAL DOES NOT WORK ! TRIED IT TWICE ON SAME RADIATOR.

[@anthonymendoza5954]

That's what she said

[@gc-cabaldoleonaldjhonpaulc7313]

Won't work. Once you put it back the leak will come back because of the pressure.

[@briandalton6077]

Hey I have same thing going on with my cavalier so the next your car was fixed with that you use they please let me know if did your next then I will buy me somes of that

[@indubitably424]

Jb weld!!!

[@JorgeReyes-lj8db]

[@1994CPK]

[@JRobling]

[@jeffreyb6165]

I have seen a couple of cases over the years where a radiator was leaking at the crimped seam where the plastic connects to the radiator and it was just a matter of re-crimping the aluminum tabs to tighten everything up. Of course I've never been that lucky.

[@upnorthvlogs]

How did it work on the radiator thinking about using it on the Polaris ATV

[@JRobling]

My follow up video explains it does not work. It gets too hot and makes the flex seal too soft

[@norman7179]

@@JRobling I suspected that !

[@Sneeezzyy]

Shake the can bruh

[@cpt.j9751]

Yeah, it was pissing me off.

[@mightypyro3172]

You sound like Ryan Reynolds

[@timothythomas2685]

Bad idea

[@sotheamam1244]

Hi..im cheap too

[@FuckaBean]

I do appreciate this vid for the idea. Things for improvement are using alcohol on the area to clean and dry it before spraying and spraying out the can for 5 or 6 sprays so it gets out the watery stuff

[@nathanwesley6422]

Hot air intake lol

[@timothythomas2685]

I was wondering how he figures that hot air is better than cold or cool air?.. Dense air mixes better with fuel than hot air

[@MondayMotorvation]

Hmmm

[@billylocklin4149]

Take it to Chief Radiator best in Dallas TX
