225,slant six radiator

Weigh the different radiator options: repair it; recore it; original used forty year old replacement, and new aftermarket unit before doing anything.

If the current radiator is showing white stuff around the fins, that is a sign that the brass is getting real thin making repair a crap shoot as to how long before the next weak spot lets go, recoreing can be stupid expensive, used is a crap shoot, and new aftermarket is, well… new, and surprisingly affordable.

I replaced my original white encrusted radiator at the advice of my cooling system repair guy of several decades with an aftermarket unit from “Radiators dot com”. The all brass unit came coast to coast in five days at under 170 bucks about three years ago, bolted right in, required only lower hose change to accommodate slightly different lower outlet angle from original.
