I will be taking my 560SEL on a 4,800km road trip to outback Queensland soon. Over the past couple of months I have been slowly sorting out a few things that could impact its reliability. This was beyond routine things like oil and filter changes. I created a list of items I wanted to address, with the first being the critical one. Occasional coolant...
Today’s job was installing a W126 radiator into my 1987 560SEC. I had previously sorted out the cooling hoses as part of my monovalve eliminator install. I was just waiting on a few extra parts I had ordered to begin this job. Firstly I decided to replace the coolant reservoir tank.

It was an IMI unit which was one of the OE suppliers and had a 1987 date code on it. W126 radiator removal is fairly straightforward. Fist step is obviously draining the coolant,...

I had a few problems – the water pump was leaking and getting...

Today, I found it does work, and that my temperature gauge is pretty accurate; The DS overheated today and I was greeted with the little temperature light and the...
