Just came across your video because my wagen is also running like 100c. I removed the radiator, which is dirty; I plan to take it to my local radiator shop to clean it.
On what I presume to be the original radiator in my 85, the connection to the upper hose completely broke off including part of the tank, one look after opening the hood I knew I was in for a very bad day, problem is I was on a remote mountain road miles from civilization, had to haul it out of there on a car hauler, which was no easy task, all expenses involved were well over $1000. A close look you could see that over the years the plastic had become brittle and crystalized, it was a ticking time bomb and let go at about the worst possible time. Point is even if your radiator is still doing it's job, but has a lot of years on it, replace it, that Nissens radiator is $165, probably about 10% of what this failure has cost me.
😊 needed this video and thank you for time lapse. Shows how you removed it. Meaning angles and such. Keep up the great work!!

After I replaced the radiator, my 83 wagon still went over 80c; now, I am considering replacing the water pump.
Mercedes sells citric acid powder that you dilute in water and run through the cooling system minus the thermostat to clean out any rust/debris.
Did it fix the problem you had with temperature climbing to 100c on highway? Im having similar issues with my W123 300 Turbo Diesel.
Yes it did.
👍👌👏

It’s common for that upper connection to break on these.
