Water Pump

[Broadwayblues]

Ok so I go to start my baby and notice a puddle of coolant on the driveway. I am leaking coolant like a mother*(&^*(^%*!!! Its coming from the water pump and I am wondering about its removal. I am going to get the pump, and it looks like it's pretty straightforward, I was just wondering if anyone has done it before. Also is there a gasket or high temp-rtv where the pump attaches to the engine?
Thanks in advance.
EDIT: just wondering, Autozone pump $30. Dealer $80. Any big difference?

there is no gasket but there is needed for the use of gasket maker, grey silicon stuff like rtv sold at any auto store

Autozone one is fine, I believe that they are remanufactured OEM cores with lifetime warranty. While your in there, might as well pickup a thermostat and change it. OEM stats are the best, around 13 bucks a piece at the Nissan Nazi Dealers
