Radiator Repair

My crf250x LH radiator got twisted up pretty good. I got it all straighten out and it looks very good. The problem is the lower hose fitting is pulled loose, just enough to leak. How are these attached from the factory? How's the best way to fix? It don't really look like it's welded or could it have been welded on the inside of tank before it was installed.

They can be tig welded.

Be careful if you pressure test it. I plugged in the wrong line and watched all the little cooling fins get smaller, which means the tubes were expanding :yikes: :bang: Unplugged in time. No charge for hp hi flow radiator :nod:

If you pressure test, do NOT exceed 13 PSI!

Best bet is to use the radiator cap to ensure that the pressure doesn't get too high. Pressure test both radiators together so that the radiator cap is always included.

I was unable to find a tig welder that felt comfortable doing the job. Wound up taking it to a local radiator shop, turns out they have a guy that specialize's in dirt bike radiators. They went over everything. Straighten everything out perfectly. Went over all the joints and corner braces and hose fittings by (weld/braze) it looks great. 65 bucks not bad for same day service.
