During reinstall of a freshly rebuilt motor we discovered one of bolt flanges (also called dog ears?) on the driver's side heat exchange was cracked at the weld. We decided to proceed with installing knowing that I would need to get it addressed soon. Well ... that flange completely broke off when mounting it.
I have no experience welding nor do I own the welding equipment - my question is can that be welded back on good as new ... or do I have to replace the exchanger? The heat exchanger is in great shape with no signs of rust or leaks anywhere. So it would be great if I can have it welded vs. needing to replace. Thanks in advance. |

You didn’t say if you were using stainless steel exchangers, I recently found I had cracked ears on two pipes. I practiced a bit tig welding a couple of stainless bolts, when I felt confident enough I had at it. I am no where near a pro but I find joining metal together very satisfying. Find a good local welder, they will have the experience to let you know what can be done. |

I don't believe they are stainless, BUT ... the gray paint is scratching off and it's shiny silver underneath. Almost looks like the PO painted over stainless. Was that ever a thing or did older stainless heat exchangers come with gray paint on them? |
