The fan shroud has a number of serrated surfaces to locate it vertically against the radiator. With the clips off, move the shroud a few mm to the rear before lifting. Oh, maybe you removed the radiator clips. The shroud clips are a little smaller.

The shroud only comes off if you have a two-piece shroud. If it's a single piece shroud as I believe came in the 88s then you drape the shroud over the fan, release the fan then remove the shroud and fan together.

... or not. You can thread the belt around the fan.

IIRC there's a bolt in the front center of the fan that takes an 8mm allen bit. I don't think it's possible to release the fan from the pulley any other way but my 300SE has been gone for a couple of years.
