on the backside of the engine
No it has electric power steering.
NOPE!!!
You don't. Electronic feed pump. If steering gets bad, go to dealer and have pump checked.
If the Nissan Sentra is leaking power steering fluid, the power steering pump will need to be replaced. This part can be purchased at a salvage yard in most cases. A new power steering pump will cost between $90 and $130 just for the part. A salvage yard will probably charge $50 to $80 for a used one.
Use Dexron II transmission fluid.
It would depend on your level of competence.
Use a flared end wrench
I own a 1994 Nissan Sentra, it has 1 belt, a serpintene type that turns all applicable ingine componants including the power steering. There is a spring loaded pully with a smooth face, there is a bolt in the center of the pully. Turn the bolt clockwise to aloow the belt to be taken off and replaced.
where is my power steering belt located
In the fuse box under the hood, right next to the battery
The 2.5L in a 2003 Nissan Sentra has 4 coils, one for each cylinder, and the power is 'sent' by the ECU from the Power Distribution box.
