Water Pump Question

I recently had the front of my engine apart for repair and now it's back together but I have a leak on the bottom portion of the water pump.

My question is do I have to drain the radiator again to take off the water pump to fix the leak. I just put it back on and I am trying to avoid anymore time consuming steps so I can get my car back on the road.

yes you have to drain the radiator, but your still gonna lose whatever coolant is in the block.

Thanks that's what I thought but I was hoping I could get away without doing that again.
