    the fan clutch is still attached to the waterpump?

    you need to remove the large nut that is threaded to the waterpump, usually you spin that irst before removing the water pump so you have some leverage to spin it otherwise your going to have to try and hold it some way while trying to break free the fan clutch

    Bobby, Thankx for the response. Actually you're answer is the point I'm at now. Before I took the pump off I didn't have any way of holding the pump from turning and there wasn't enough room to do anything, so I took it off as an assembly. I have in the last hour found that there is a special tool to make it alot easier. Hopefully it will work for me. Thanks again for your response.
