If its the same as a w211 e55 dead easy, Screw/torx LHS of the Fan shroud that the Oil cooler pipes, one at the bottom that the Atf pipe bracket holds to. Push the Cooler pipes up and back out of the holder on the plastic shroud.
Pull up and out the metal clips at the top of then shroud one each side you may have to pull the upper rad pipe off from the OSF then you can pull the whole shroud up and out. Note you will have to unplug the electrical connector on the LHS shroud.
I cant remeber if you have to un bolt the centre forward slam panel sorry.. But again its very easy.
Hi, As Gavin says plus you need to work from both below the car and above! would put the car on car ramps
and then take the two plastic covers off from underneath to get to the two 10mm bolts that hold the coolant pipes to the fan housing when these are undone you can pull the fan housing up after disconnecting the electric plug on the left hand side, and you do need to remove the top slam panel to be able to lift the fan housing out
Hi Zoros, Yes referring to E55! as Gavin says yours is probably a bit diferent but very similar layout,
People speak quite highly of Nissen Radiators of Ebay etc but i have no experience my self,
