It's time to drain and fill the radiator in my 09 Max. Can anyone tell me where the drain valve or petcock is located. Nissan dealer said it somewhere on the fan-side surface of the radiator down low. If not, I need to take off the hose.

 

Not sure on the 7th gen but Id look on the bottom passenger side of the radiator for the drain plug(that's where the 5th gens have it). The dealer could be trying to confuse you so you get frustrated and let them do it lol.
