Radiator leak repair using JB water weld

This vlog is about fixing my Jeep Liberty Radiator Leak. The Leak is coming from the plastic part of the radiator. I use JB water weld that I bought at Canadian tire. JB weld have different types of product like for extreme heat, for steel, for plastic. Jb water weld works on, fiberglass, PVC plastic, copper, brass, iron and aluminum and can resist water, oil, gas, diesel, hydraulic fluids and other chemicals with the strength of 900PSI and can withstand 300°F. My initial try failed but after my 2nd try and pressing JB weld hard to penetrate the crack of the plastic then let it cure for 24 hours worked. This is actually done last year and no problem with the leak even after 10,000km run.

Saved me 350 bucks and i paid 10 bucks for that stick no more leaking coolant I let mine sit for hour and a half that stuff is hard like a rock

[@GePete]

yes, it really works. i always have it in my car for emergency

[@The-Man-Right-Chea]

Does it withstand the Heat when coolant gets extremely hot????

[@JimmyBoy87]

@@The-Man-Right-Chea yes it’s been almost a year no leak still but I do plan on changing the radiator if it leaks again but for now I’m good hope it stays that way until I trade it in 😅

[@The-Man-Right-Chea]

​@JimmyBoy87 I just was another guy using the JB WELD High Heat which they say is much stronger. So I'm going to try it since I'm using on a semi truck 🚛

[@ricardo07serrano96]

@@The-Man-Right-CheaI just bought the water weld for a small crack on my radiator I was gonna get the red job weld how’s it working so far

[@ezwa9979]

I think that works beter then JB radiator weld, ironically👋

[@Nzaf001]

I'm going to try this on my is300 heater core return pipe. The whole dash has to come out to replace it so I'd really like to not do that.

[@rsarkees]

My ladyfriend got a leak between the top plastic tank and the crimp that holds the top onto the coils. I’ve swapped out many radiators, so like a dumbass I volunteered to change hers.
Little did I know that on a ‘05 Mazda 6S (3.0L V6) the WHOLE FRONT END OF THE CAR NEEDS TO BE REMOVED TO GET THE RADIATOR OUT!
Going to try the Water Weld today because @&#% that! Will update.

[@GePete]

as long as you have access to the leak. you can fix it with the water weld. goodluck

[@FlatOutNorth]

I love mazda but yeah thats too much

[@AUDIO2AUTO]

The 2 part is a tremendously better product than the sticks.

[@justinsocali]

Im Bout to try this myself on an Altima will be back in a week to see if it worked for me as well. Great idea man.

[@erickespinosa9466]

Did this work for you?

[@drecarter694]

Ya bro lmk sum , doin tht shit on my Altima too

[@DARKthenoble]

Oh shit, he dead

[@samuraiastronot3090]

Did it work

[@ronjose51]

This foo never came back

[@tayoni800]

Is JB much stronger than metal epoxy adhesive, which is a mixture of two adhesives (hardeners)?

[@GePete]

im not sure with metal epoxy adhesive cause i did not try it yet. I used water weld because of liquid/coolant in the radiator.

[@bamaballistics]

My leak is in the top corner on the inside where one of the tubes goes into the side. Very hard to get to on account of the cooling fins. I hope this stuff holds up because a new radiator for this thing is $200 and has to be ordered.

[@GePete]

good luck. i hope it is a plastic component. i drain all of my coolant for my second try then cure for 24hours

[@omnilife6660]

@@GePete sucks having to purchase new coolant every time just for tiny little leak

[@joevette6290]

Ok but did you shut off the engine and check if it leaks again ?? When the engine is shut off the pressure builds up alot more than when you're reving the engine at 4000 rpm!!

[@GePete]

yupp, it did not leak even the next day when i left a bucket underneath and check it.

[@zztop8592]

The real test will be after 2-3 weeks of driving.

[@vicc3337]

Pressure does not build more when the engine is off....

[@tylerbrogley4687]

I put this on my explorer 3 days ago. How did your get hard in a hour. Mine is still soft even after days?

[@GePete]

It dried up after hour but when i started to check. It still leaked. Maybe it dry outside but inside, it was contaminted with coolant. So i darined the coolant then reapply, you will see the failure with 1hour and the good result of 24 hour curing if you watch the whole video.

[@td-12kx53]

You just didn’t mix it good enough. The activator Needs to be thoroughly mixed

sounds like ED has set in strong for you........................

It’s been one year did it leak or bot

[@GePete]

I sold it last year to upgrade to truck. For 1 year of use after i fixed it, i did not see any leak

things people will do to avoid buying a new radiator

[@jimmyboyer9392]

lol yeah let it sit longer

[@JeepTJWheelin]

Yeah this definitely falls under replace, don't repair category.

[@redstreet7704]

How long did it hold?

[@GePete]

did not see any leak even after 1 year sadly, i sold that jeep

[@redstreet7704]

@@GePete Mine never held with stop leak so I bought some JB Weld and that leaked too. I bought and installed a new radiator so far so good.

[@tayoni800]

4 minutes 40 seconds There was a coolant leak, but how many hours did you start the engine after work?

[@GePete]

After the first mistake and re doing it, i let it dry for 24 hours, refill with coolant then start engine.

[@tayoni800]

@@GePete Now, isn't the coolant leaking?
