You don't need to remove the fan pulley but you will need to remove the distributor cap to get at it. Don't forget to get a new o ring for the heater pipe where it goes into the water pump.
The radiator can go back in. A new fan clutch is a doddle to put in later.
If the hose between the engine and thermostat still leaks then you have no alternative than pull the water pump.

By the way, which direction will the coolant flow out of the water pump when I start up the car. I need to flush the wrong coolant that is in the car right now (its green, thanks to the indy) and put in the yellow coolant which I also bought today from the dealer. I figure once I reconnect the clamps, etc. I will just redirect the hose that goes from the water pump to the radiator into a bucket. Then start teh car and have the fluid pump out of the engine into a waiting bucket. However I am unsure which of the two hose is into the engine and which is out. I am talking about the upper & lower radiator hose. Any idea which is which?
