I have actually removed the radiator from a M103 190e.
Disconnect the radiator hoses. Disconnect the auto cooling pipes.
Remove the fan shroud - it clips in..
Remove the top radiator support - it bolts on - move it out the way.
Lift radiator out.

It takes all of twenty minutes if you are slow.

Caveat - Right Hand drive model.

The hardest job is getting the fan shroud back on properly after putting you new radiator in.

If you want to work on the front of the engine - it's advisable to remove the radiator in case you damage it. - There is no room in the front area of the engine. The M103 was shoehorned into the body.
