There is a special tool that you will need to\015\012remove the fan clutch from the water pump. Basically what this tool\015\012does is uses the four bolts that you removed to hold the pulley so that\015\012you can unthread that fan clutch assembly. Here is an illustration of\015\012these items as they come apart.

You\015\012should be able to check with your local auto part stores to see if they\015\012possibly rent a fan clutch removal tool out. I know autozone does rent\015\012this type of tool.
