There is no easy way, water pumps are hard to change on this vehicle. Before starting the job I would buy a repair manual with step by step instructions. To give you some idea on how long it may take, the labor time is 4.5 hours for an experienced tech.

Figuring off of national standards thata gasoline engine is allowed to burn 1qt. of oil every 2,000 miles tthey would be correct.But That is not to say for that particular engine providing that oil has been changed every 3000 miles,There could be other problems contributing to your car,for instance cklogged pcv valve,leaking injectors or fuel preasure regulator both can cause fuel contamination to engine oil (Dillution) Thins oil too much,or overheat condition,or failed cat convertor.With this in mind talk with another Nissan dealer if only by Phone.
