Good day. I am undertaking replacement of the fan clutch on my 1994 E500. I am replacing the water pump, radiator, belt, etc., so I have plenty of clearance, but I cannot get the fan clutch 8mm hex bolt loose. I see that several businesses (including Pelican) sell a fan clutch removal tool - a c shaped wrench with three holes. I am fine with buying the tool but want to make sure it is the correct one. Any suggestions will be appreciated. The bolt is on fairly tight - holding the fan pulley via the belt or by hand is not sufficient, and I do not want to grab the pulley with pliers. I saw a video elsewhere on this site but I do not have facility to make my own tool.
