Ford Repair: fan clutch removal, aerostar van, fan clutch

Question
i have a 1986 aerostar van i dont know how to remove the fan clutch please help

Answer
if it is screw on look on fan shroud to see if it says left hand thread or not-other than that it comes off with a big wrench that fits fan clutch nut and you have to hold water pump pulley with a tool that either looks like a very wide wrench and it fits on outside edges of water pump pulley bolts or one that has two hooks that grabs two bolts you have to hold that while turning other wrench-sometimes a sharp blow with a hammer will break it loose.
