Radiator Leaking - Need suggestions

Hello..

I have a 2000 426. Noticed a small leak on the left radiator inside bottom corner. Took the radiator off to inspect it. The crack is in the corner where the radiator side rail is bonded to the bottom pan. It looks like an easy solder repair job as it sits in a little channel. I tried some lead-free plumbers solder and flux that I had around but it would not stick.

So, what do you use on aluminum?

Are there any alternative fixes out there besides solder? Trying to save some moola here.

Thanks,

M@T

I had a similar problem with my 99, was able to take it to a radiator shop and have 'em "glue" it. It held for a few races but still ended up buying a new radiator.

I had the same thing happen to me and used JB weld. I took a piece of aluminum and used a file to make some aluminum shavings, mixed it with the JB and it worked. I would think a radiator shop would be the best option though. You might look on the BBR web-site as they are parting out some new 426's.

All spamming aside, Fontana Radiator in SoCal does excellent motorcycle radiator repairs, including welding a leaky seam.

Another place that I had good results with is MYLERS

Good solder should work, the key is to get the area very clean, and use a wire brush on a small dremel tool or some fine sandpaper to get good clean roughed up surface to sink into. It is hard to get the right amount of heat into the aluminum cause it disapates it so quick, I use a good butane burner for smaller jobs , if you can elevated the area you are heating that works well to, It is surprising how fast the aluminum will absorb the heat, but hey, thats its job right? If your not to keen on the repair, a Good rad shop shold be ok, the problem with the small rad especilay on the side rails is thats where the stress is. I have never had much luck with the JB weld at all,,, maybe I shold go get some and refine my tecnique??? Sounds like a good addition to the trail bike first aid kit.

Trail tip

In a pinch on the trail, you can cut a core and crimp it by folding it over a few times, this only helps when the damage is in the middle of the core, I would not recomend just blocking the core off as a permanant fix on such a small radiator though :)

Good luck.
