How to fix a radiator leak! Permanent $15

So it takes less than 5 minutes and you can stop a coolant leak and so much more just with a inexpensive plastic welding iron. Watch how to weld plastic the fast and easy way. No more cooling system problems or leaks.

I once plastic welded a radiator with a soldier iron and weed whacker string it held for 3 years and I sold the truck like that

Watched a guy do one of these repairs by melting black zip ties.
American ingenuity love it! 👍

The rods that come with the welder are Polypropylene (PP) which melts at 266 degrees fahrenheit (130 celcius). Normal car operating temperature is 195 to 220 degrees Fahrenheit. If you are going to weld on plastic then use Nylon (PA) rods which is what the radiator is made of. Nylon (PA) melts at 428 degrees fahrenheit.

A cheap soldier iron that's used for electronics an plastic tie straps work great..I use it on everything that's plastic an never had a problem even a radiator that was full of antifreeze an it still welded together an works perfect .👍👍👍

When plastic welding add some thin copper strands for added strength 👍

I tried the jb weld epoxy and it didn't hold at all prepped and cleaned properly, today I remembered I had a plastic welder took me 15 minutes and looks great

[alexgomes]

That how I fix mine too bro. Great ideia. Thanks for sharing it.

JB waterweld works very well an is permanent but prep is key! MUST BE CLEAN AND SCUFFED WITH SAND PAPER!! also looks better too

i used flex seal. worked like a charm

If one is welding a plastic gas tank, the tank is made of HDPE plastic, the same thing that oil bottles are made from. Cut some strips from a clean/ empty oil bottle, and grab a soldering iron or soldering gun, and carefully heat the area on the gas tank that is damaged, and melt the strips into that area, being careful that the plastic covers the area enough that it won't come loose. If the tank is removed, it can be tested with water to see if it leaks.
This only applies to black plastic gas tanks. For white tanks, use an empty isopropyl alcohol bottle the same way as mentioned above.

""Fix a leak for 15$""
""This plastic welder costs 20$""
🤣🤣🤣🤣🤣🤣🤣

Not to be cheep but the kit in the link is $32. HF has the same thing for $16.99...

Better way to repair a cracked radiator with plastic casing, split the plastic casing off, then you can patch any metal with jb weld or another solid epoxy or high heat water resistant putty unless you wish to weld in a new panel piece thats been roughly shaped. As i presume the radiator is made of a metal or alloy and this has rusted and failed, and the high pressure and heat lead to the leak perforating the plastic case. Then you want to use plastic cement/plastic weld to fix the plastic case and reinforce it.

If all your doing is melting plastic to fill cracked plastic, it wont be long before this fix fails as due to weathering and operating temperatures, the plastic will eventually break down under the high heat and pressure.

That part that’s leaking… what’s it called? Mines cracked all the way down. I’m willing to jb glue it with high temp and also burn the plastic together till I get a new one. What can I do? It’s a crack that goes all the way down but it’s thick . Toyota carolla 2007

[markcarter]

No. This is not the right way especially with the nylon tanks.
You cut a small screen that comes with the Harbor freight kit and melt the small screen that comes with the kit right down into the plastic. that method will work much better.
The screen that comes with the Harbor Freight kit is made out of stainless steel. So it will never corrode.

what if the radiator has sprung a lead just under the top hose? can that be welded?

[cD-vggo]

3rd time i used my welder just like yours the tip bent and fell off now i gotta unscrew the center. You should unscrew yours drill it out and slide back in the iron

[YHKceemrniceguy]

Do you have to take out the radiator to do this or can you just weld it yourself while it is attached to the car?

[travisaleric]

why did you blur out your propane tank? lol

[DavidRamirez-ckph]

I worked with I had the time. A solder iron and with zip tie.
