Just to add your only realistic option is to fit another Mulfab radiator given the demise of SiFab a couple of years ago. Ironically the owner Simon previously worked for Mulfab. A liitle surprised existing Mulfab rad has rotted away, albeit after 13 years. Can't help but wonder what coolant you were using
In 2008, Simon was making 50% of the Mulfab rads, with a notably higher failure rate than Peter's so I am not surprised. As for today's Mulfab, they are not the Mulfab we had under Peter Mulberry. However they do have Peter later designs which are infinitely better than anything else available in the world at the moment. II have tried out four Peter Mulberry rads. Never had one fail. BTW, this is a sad area for trads as the rads could be so much more improved. And rad fans have come so far in 20 years! The traditional metal Morgan rad thickness and canting in the non-Mulfab aftermarket is counter-intuitive.
However, I'm with you,.
How does an aluminum rad rot?!!! Something is missing. With respect, it is perhaps a less than precise explanation. I have only something like that seen that with a major US rad source where they epoxy joints rather than weld them..epoxy does not expand and contract so sadness is inevitable.
