- This Do It Yourself video shows how to repair a crack in a radiator that leaks coolant or how to fix a leak in a radiator or how to stop a leak from radiator on a Toyota, Nissan and any relevant car. My radiator was leaking coolant for a while until I notice that there is a crack in the radiator.
This video displays how to seal a leak or a crack in a radiator. You can repair a leaking radiator quickly and easily using JB Weld = amzn.to/3gcq5bI
This video is good for plastic radiator or metal radiator.

My JB Weld plastic radiator repair lasted 2 years before the JB Weld began to peel exposing the crack along a bend and bolt mount 90° corner. So, I am going to just add JB Weld at the failed peeling location. Yes the area was ruffed as good as could be in the area of the crack. I realize that these weak areas are created in the molding process where thin areas are created.
You forgot to drill 2 holes at each end of the crack si it wont crack any more.
It Worked!!
I had a pretty large crack, in the plastic top of my radiator, coolant was gushing out, it's a few days, and no problems yet!
THANKS!
hopefully it will work long time
How long it last?
@@Tyty-xv5fq Still working perfectly!
Fixed one mine that way , it blew a hole big enough to put 3fingers in and wiggle room . Cut some clear milk jug squares jbed one then a slightly bigger one over it lasted yrs just kept an eye onit
How long did it work for you guys?
Does Marine JB Weld work on a car radiator?
Hi there .. I need some information on how I can fixed the crack ? I can’t afford to fix the radiator as now
Follow the video.
This video was worthwhile
Any time.
Job weld fixes everything for real
Can this be done if the leak is on the other side of the radiator, facing the engine bay? Or is it just smarter to get the entire radiator replaced?
smarter to get the entire radiator replaced
@@josephk9182 Thanks for the reply. After more research, I went ahead and ordered a replacement. It will be my first time installing a radiator, so wish me luck!
@@gseric4721 I made 3 videos regarding how to replace a radiator here is part 1:

Also look at how to fill radiator:

I hope it help.
@@josephk9182 Wow, really? Thanks for telling me. I'm working on it on Monday, so I'll make sure to check them out.
Hi Joe so I was told by my mechanic that I have a crack in my radiator and I got the supplies from your video but I looked and I can’t find a crack but I do see some dried coolant around the big black tube (not sure what it’s called) that connects the engine to the radiator. Any ideas? Please help. I just need to get this as a quick fix until I can afford to fix the whole radiator if it needs it.
Did you lost coolant water ? Did you need to fill up coolant into the radiator ? You need to find where is the crack and apply the glue on it when the car engine and radiator is cold and let the glue dry for a day or so.
Is drilling two holes on each side necessary?
Can a crack radiator be fixed ?
Yes but it depend.
Thanks Joseph. Good video. Unfortunately, we only have PC Fahrenheit Hi Temp epoxy. Will it work on a small crack on plastic of the radiator. Thanks
You should sand the area where the crack is and put apply the epoxy. Make sure the epoxy can stand 212F (100C) with 20 psi pressure.
I tried this and followed the steps 100%. After 2 hours of drive the patch broken and coolant is leaking.
Here are the steps followed,
1. Drained the radiator 10 hours before.
2. Cleaned the crack area to remove oil stains
3. Used the steel scrapper and sand paper to make the crack rough
4. Mix the both in 1:1 ratio and applied on the crack as shown in the video.
5. Left the vehicle for more than 24 hours(almost 30 )
6. Filled the radiator with coolant.
It was good for first ride up to 60 miles and then I checked how it was, so the patch became smooth like rubber because of heat/pressure and coolant was leaking slowly. The patch lost the grip on the hot surface of the radiator.
Did I miss any step ?if not why it lost in such a quick time.
What king of radiator you have (plastic or metal)
It’s metal (1999 Camry LE)
where is the location of the crack and how big is the crack ?
It’s a bit bigger than you showed in the video... it’s narrow line
@@maruthichava4202 some how the JB Weld was not attached properly to the metal surface. You may have rusted metal so you need to remove the rust using a circular sanding paper. Remove all rust 1/2" from each side of the crack. Did you verify that the JB Weld you bought is working for higher temperature. You must buy the one that work with the highest temperature. Also apply the JB Weld 1/2" from each side of the crack and push it into the crack.
does it still hold up, how is it working now after a year?
I sold the car 2 month ago. It was working with no issue, remember the most important is to scratch the metal that the epoxy will stick to radiator. When the coolant reaches 20 PSI the radiator plug will open and the water will go to the reservoir. So the pressure should not be an issue if your radiator plug work properly.
Tried it last night, it worked for a while today but eventually cracked the epoxy. Believe the radiator gets too hot for this
Jim it is not because of the heat, it is the pressure. You must mechanically scratch the area very well and then apply the 2 parts epoxy. You should put the epoxy on a cold radiator and let it seat for at least 24 hours. You must use the epoxy that is suitable to sustain high temperature. The patch width should be at least 1/2 inch . (1/4 of an inch from each side of the crack.) I hooe it will work for you.
@@josephk9182 the epoxy I used says it can resist 250 degree Celsius of heat but it only last for 10 minutes before the coolant shoots out again. And I used the stop leak stuff still didn't work so I gonna try welding or soldering for the last resource before taking it to the mechanic, just feeling frustrated.
It is not the heat but the pressure. The epoxy should stick to the radiator but if the area where the leak is not rough it will not stick properly. You need to sand the area and than apply the epoxy when the radiator is cold. It should stay at least for 24 hours before driving.
Great video!! You should throw in a few everybody get down! And California!! And I'll be back! :) Great video and pimp accent dude :)
Thank You
I'll be back !!!
Very pimp accent 💪🏼
Hey, I followed your video, and it worked! Thank you 😊
Very good
If anything get the marine jb weld
That's what I was told, so I got it and did the repair today. Will see how it works after I let it set for 24 hours
Brandon Schwartz how did it turn out?
Does Marine JB Weld work on a radiator?
@@brandonschwartz2395 Does Marine JB Weld work on a radiator?
you should have feathered out the edges after you removed the tape. But nice JOb.
Great video!
Thank You
Genius
Thank You.
If you make long commutes, buy a new radiator. This repair isn’t worth being stranded on the highway.
