Question/Opinion. I removed my DeWitt aluminum radiator today and stock clutch fan to install electric fans. I noticed where the radiator had a lead around the filler neck. Upon closer inspection it appears the overflow tube connector was not properly welded, almost like it was just a pressure fitting.

I'd find someone that can weld aluminumnum, and have it welded properly. Not sure if JB Weld, or other epoxies would do the job.

I'd call Tom DeWitt. He stands behind his product.

After calling around looking for a radiator shop to do the welding and finding no one in my immediate area, i stumbled across a low heat aluminum braising rods from Harbor freight tools. It was a simple process of cleaning the area with a stainless steel wire brush (also harbor freight) and using a propane torch to heat the area then flowing the rod into the weld area. Worked like a charm ! Nice and clean and after completion, the allow is harder than the aluminum. Now to see how long it lasts. Based on what i'm seeing, i dont have any reason to think it wont last. it made a very strong joint ! So something to think about for those of you in this situation. Only $17 for the rods and $5 for the SS brushes.

I agree, DeWitt's make a quality product that they stand by...call them up.
