How do you replace the water pump on a 1987 Toyota Panel Van?

[BG wants to know...]

My fiance owns a 1987 Toyota Panel van and it needs a new water pump. Does anyone know where he can find instructions for free or very cheap on how to replace it himself? Or actually know how to do it? I've found info on replacing a water pump in general but hoped for some for the '87 van in specific, and repair manuals are very expensive. Thanks!
