IIRC, the Honeycomb is made up of "strips" which are soldered together to make full tubes and then formed in a press to the zig-zag shape of the honeycomb.

A rod will not pass from one end to the other because of the zig-zag, and the strip construction is prone to leak either in freezing - or simply "solder corrosion" of the joint which all 60-40 solders are prone to.

I have had my honeycomb boiled out, created a few leaks in doing so, repaired the leaks, only to find a few more until it got set aside.

Everything has a life - the honeycomb deserved a rest. I will give it credit though - even before boiling, the car never boiled over.
