Replacing the power-steering belt on a Nissan Sentra is of great importance because the drive belt wears over time due to the heat in the engine bay and stress placed on the belt from the continuous tension placed on it. The belt begins to crack and eventually breaks, causing the power-steering pump to become inoperable, potentially causing an accident. To prevent such troubles, inspect your belts periodically and replace if necessary.

Open the bonnet.
Loosen the lock bolt with a ratchet and loosen the belt tensioner until the belt is loose enough to remove. The Nissan Sentra uses multiple drive belts rather than a serpentine belt and therefore requires that each belt be removed separately with its own lock bolt and tensioner.
Pull the power-steering pump up and down repeatedly until the belt comes out without significant force.
Install the new power-steering belt onto the power-steering pump pulley and crank pulley.
Tighten the tensioner until the belt only has approximately half an inch of deflection. To check, you can utilise a ruler and place it vertically against the belt. Push down on the belt and measure how far down you were able to push it. If you are able to push it more than half an inch, it is too loose. If you aren't able to push down to half an inch, the belt is too tight and could cause damage to the power-steering pump.
Tighten the lock bolt to keep the tensioner in place.
