Mercedes Benz repair: fan clutch removal, clutch tool, fan clutch

Question
Mercedes Benz 1991 300 SEL.  engine = 103
I bought kl-0366-6 120 589 02 01 00 to remove
radiator cooler fan clutch.
Can you tell me how do I engage it.
I see the fan clutch is attached to a pulley which
is also attached to engine with bolts.
Does this Klann tool slip into above mentioned bolt heads which reside between fan clutch and pulley.  

Answer
You must have the following tool to remove the front center bolt from fan clutch, allowing fan/clutch assembly to separate from engine.
