Fix a Radiator Leak REDNECK STYLE

[jakemakes]

I like testing stuff. Yeah, the smart move would be just replace it. But that’s boring. I’d rather test a JB weld fix and see how it well it holds up.

That look you gave at the end instilled all the confidence I needed

Oh man you are awesome... your vid helped me repair my car radiator leak at the onset of a five consecutive public holidays Hope it works long enough.

Just buy a replacement, older a radiator gets the more clogs it develops in the lines thus less efficient cooling. My old 07 Silverado rad blew up from simple driving was clogged beyond. Fans were basically always on even in 40f temps. Once replaced fans barely came at 60f.

Don't cheap out, you already took out the rad l, just replace it fully.

An upgrade to this method:
Before applying the JB weld, the thin blade of a knife to open up the cracks in the tubes, then connect a vacuum cleaner to one of the hose ports, blocking the others off.

Turn the vacuum on, then apply the JB weld so it gets sucked into the damaged tubes. Turn off the vacuum and pinch the tube closed, applying a little more JB on the outside. This will prevent internal pressure from blowing the JB weld off of the tubes.

Alternatively, you can use red high temp RTV. It works just as well as JB weld does and is cheaper.

I have used JB weld on a radiator it does work, how he did it and where he used it but it may not work for every type of radiator repair I have learned that on trying to repair a leaky area where the transmission cooling lines go into a radiator on my old Ford truck, vibration knocked it loose and JB weld did not solve the leak forever

[Mr.Mister]

Just use lead solder. Lead free is more difficult. Just be sure to get flux/acid. Super easy and that's what the radiator uses.

Not sure how good jb weld will work but better than nothing.

smart and simple but i can’t imagine that lasts long at all

In the same line as this fix....

In 2005 my friend had a 99 civic hatch with a K20 from a RSX in it. The car was lowered and that engine sits low as well. Well... he hit a manhole cover in his GFs neighborhood and I fixed it with a dime covering the hole and JB weld quick. We might have gave it 20 min. Poured in the oil and sent it. It worked until he did it the next time. I fixed this 4 times using the next size coin each time.

Aluminum soldering is not difficult, heat the area with a hot air station or heat gun, take a soldering iron (one that doesn't suck ass) and some acid core solder and do like you would normally solder. Well, relatively normal.

Jb weld will eventually fail woth liquid like that, I had some to seal my windshield wiper fluid and it lasted for about a year or so before it started leaking.

[ChaoticKameleon]

I bought a brand new radiator, brand new electric fan (hayden), and ended up having a bad thermostat so as i was pulling the hose off of the thermostat my kleins slipped and i knicked the radiator of course after doing all of that it poured coolant out of the little hole so i did exactly what this guy dude but just with one tube, its curing rn. Hopefully it turns out alright.

[ChristopherGreene-fn]

Do they still make "Barrs-leak"? That shit worked great!

[TurinTuramber]

Did you fix the fan, it will just contact the JB weld.

[exenctric]

how does your fans make contact with the radiator? loose screws or did install them to close

[captainCrunchconservative]

solder and a blowtorch but if it worked it worked

[CyberChrist]

Stabilize your fan/radiator mount first.

[ололо-ъз]

Well, that works as a temporary fix, but it doesn't seem very reliable. There's quite a bit of pressure in the cooling system and I'm not sure if this would hold for long.

[scottmochinski]

That’ll probably void your warranty, huh?

[MauiRedMan]

And the price of a new motor is a lot more expensive than a price of a new radiator don't be a cheap ass and don't follow this guy's instructions
