The radiator was gone through and repainted by a radiator shop. To be honest, the result sucked immensly. It looked filthy on the inside, most of the fins in the radiator core were bent/damaged and the bad paint job also had started to flake.
A completely restored radiator
So, I removed all the paint, cleaned and pressure tested it n the same way I did the heat exchangers for the ventilation (see the article Heat exchangers). I spent a couple of hours to straighten out all the bent fins and after that I put a thin layer of Eastwood's Radiator paint, black satin.
The thermostat was treated in the same way.
I’m not sure the English wording is correct for these items, extras needed for the cold Nordic climate. Let me know if you have the right terminology, or if you know anything about these items.
Not yet restored. This is a Swedish variant of the radiator jalousie, probably mounted by the importing company, Philipson, at arrival and before handing out to the client. Could also be that my father installed it afterwards, by himself. Unfortunately I don’t know.
Not yet tested. If it is an original MB-product or some sort of aftermarket cover I don’t know. I got it from an old, within the Swedish Mercedes-community well known but now deceased person.
