How do i tighten power steering belt on a 1991 Nissan sentra
This is just a general answer. There are 2 ways to tighten a power steering belt, 1, by adjusting the power steering pump OR 2 by adjusting a tensioner pulley.
Inspect the belt system and see which one your vehicle uses. If the pump is adjustable, it will be mounted on one end by either a sliding bolt on a curved bracket like the alternator, or by an adjusting bolt.
If your car has an adjusting pulley, check the routing of the belt. It will normally run from the front engine pulley over the adjusting pulley then over the power steering pump pulley. The adjusting (tensioner) pulley will have to be loosened, then either pulled to the tightening position by hand and retightened, or else there will be an adjusting bolt and nut which must be turned to tighten the belt before retightening the pulley.
Sorry, I don't know your car that well so my answer is just generic.
