EGR valve replacement, HELP please :(

I just got my new EGR valve from Sewell Infiniti in Dallas TX. and I need to know how to install it, I see it clearly in my engine, looks as easy as two nuts and a rubber tube, but is there more to it? do I need to drain something, start the engine? or something like that?

thanx everyone

Just remove the old EGR and any gasket material, replace gasket if needed, bolt down new EGR connect vaccum hose and start car. Make sure it runs ok. Then shut it down and reset the ECU. Start car, make sure no EGR MIL code pops up and drive away.
