Radiator Repair - Aluminum Brazing - Motorcycle - 2007 Kawasaki ZX6R - HOW TO 

Thank you for this post I have the exact same bike same year and couldn’t find where I was leaking coolant until I saw the video, my bracket broke as well

My 2007 ZX-6R had the same problem! The bottom radiator fan mount bracket breaks and causes one of the mounting bolts to constantly slam into the radiator until severe leaking occurs. This is most definitely a design issue and manufacturing defect and should be recalled by Kawasaki!

I like jb weld but know it won't hold up... I've used jb weld on my cj7 dash to cold weld a couple of my switched to the back of my dash and when I sanded the top of the dash, the weld broke off of the wiper switch. Had to reweld it..

nice I used Quik steel 2 fix my Crank Case that had a hole the size of my thumb 1 1/2 '' & Crack on 1100 Honda in 2014 still holding oil for 2 years now ***** ty for your video

I just bought my zx6r not to long ago and the same thing happen but it happen before I bought since the fan was poorly rigged by the previous owner with extra confusing parts I guess I have a leak in the middle where the center of the fan has been touching Im going to try to weld it today or tomorrow

nice one, thanks

Thank you very much about posting this! I actually have a NLA radiator with a hole about this size that needs to be fixed. I had it for well over a year wondering that to do with it. Might have saved me $450! Thanks! :)

Yup exactly what mine does!

I had the Exact same thing happen to my ninja,,I made a lil Bracket from my rubber mounting hole,,,Plus...I put soft black window foam around the outer plastic frame of my fan,(where it would meet up with my radiator,,Still holding after 3 years,My friends Suzuki already has the soft foam Factory on his....

Did the rad fix (hole) work ? Mine just started leaking FML ! !

I've got the same problem! also with the fan on the same spot.

Well how did it hold up?

Word of the day " Flux ". With flux, the aluminum would channel into the cracks where it's supposed to bond.

Heat the parent metal and allow it to melt the solder. Don't melt the rod with the torch or you will get a cold solder and it may not hold. Good first try though. Flux will also help you. When the flux bubbles you know your ready and the solder will follow the flux and fill and bond much much better.

I have the same exact problem to the T. Before I try doing this I want to know if it's worth it. Have you had any problems since you've done that?

Problem still solved?

Did this hold up for a while?

Propane without oxygen does not get really hot.....kinda tricky when trying to braze.

This is a manufacturer design defect and should be recalled by kawasaki. I had this happen and there was coolant everywhere including some on my rear tire. The bottom mounting tab will continue to break even when re-welded. I wonder how good the JB weld will hold up down there, I might try it or even eliminate that bottom mounting tab, bolt and nut altogether somehow.

Interesting video. I just bought a new radiator but the side of it is crushed in some (not big but enough to see that its squished in). How much will it cost to repair it and will this dent cause any issues? Seller is offering me an $8 refund.. It seems on the low side to me..

Hello are you there... I need some advice please

JB weld is strong as steel. no worries....that bracket wont move again.

So did this ever leak?

Same exact problem on mine 2

Same exact spot I just got a leak at!!!

I have the same exact problem lol! same bike

Dude!!!! Thank you VERY much!!!!! I have the EXACT same bike down to the same color. As soon as I finished this video I check my fan thingy. Guess what? Same problem. How long did it take you to complete the job and do you live in vegas?

Was it running hot ass well??

A- you have to clean the area B- you need MAP at least. oxy-acetylene would be preferable

Heat the metal being brazed, not the rod. Get metal hot enough to melt the rod.

can i use aluminum foil?

anyone doing this just put the radiator in the oven for 30mins so that the filler sticks better to it

Also , if you lay the rod in the crack and heat the shit out of it, you won't be able to tell you even welded it. Believe me I've done this before.

You had up until you said in weld lol nice first try dude

You clearly didnt clean it enough first

that aluminum brazing,, not good for leaks may be for other thing but when it comes to leaks, jajjaj is just a no the right thing to use!!!!!
