I dare say there's a few threads on this very job, since its quite common. I can only use the search button as well as you, so a seach using appropriate terms should find something. Haynes manual covers it (indirectly) but I think its a bit vague. From memory, you need to remove the fan, drivebelt(s), and then start unbolting things at the front of the engine. Since you need to drain the coolant anyway, you could remove the radiator to create more space to work in.
