How do you change water pump on ford probe 1996 2.5lt 24v v6?

How do you change water pump on ford probe 1996 2.5lt 24v v6? Will i need to drop the engine out or is it simple enough to do at home with a friend whos a mechanic?

I would rather fix it at home to save the costs of labour at a garage!

A step by step guide form anyone would be very much appreciated and notes on the tools i will need!

Thanks in advance!!
