Tolerance of water pump play?

Thats what i was thinking, i can only hope that i can change it out without disturbing the seal on the timing cover. I know if i loosen the bracket to adjust the power steering belt it will weap a little coolant from between the water pump and timing cover but seals back up after you tighten it

I think it will be fine. I've changed countless water pumps on small blocks and never had to remove a timing cover because of a leak. Now a broken bolt on the other hand.......
