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.

It is a black reservoir to the left of the engine. A small dipstick is attached to the back of the cap to measure the power steering fluid level.
In a Nissan Sentra, the power steering fluid reservoir is typically located near the engine, often on the passenger side. It is usually marked with a steering wheel icon or labeled "Power Steering." To check the fluid level, simply remove the cap and look at the dipstick, if present, to ensure it is within the recommended range. Always consult the owner’s manual for specific details related to your model year.
