Question about 1994 Nissan Sentra 4-Door

Open Question

I have a 1994 Nissan Sentra with no A/C. I can't get the Power Steering belt off--I loosened the tension adjustment bolt and the lock nut on the side so the tensioner is lose, but the pulley and the belt stay tight. Is there a bolt on the pump that I need to adjust to get some play?

Is there a trick to loosening the power steering pump pulley to remove the belt? Thanks!


Loosen the pivot bolt. Most have an adjusting bolt and a pivot bolt where the PS pump can move back and forth a bit.

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.
Good luck

How to replace the power steering belt on a 4g13



ADJUSTMENT

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

Drive Belts

INSPECTION

See Figures 1, 2, 3, 4 and 5
Check the condition and tension of all drive belts every 12,000 miles, or at least once a year. Loose drive belts can lead to poor engine cooling and diminished alternator, power steering pump, air conditioning compressor, or emission air pump output. A belt that is too tight places a strain on the bearings in the driven component.

Fig. Fig. 5: Installing too wide a belt can result in serious belt wear and/or breakage
Replace any drive belt that is glazed, worn, cracked, or stretched to the point where correct adjustment tension is impossible. If two belts are used to drive a component, always replace both belts when replacement is necessary. After installing a new belt, run the engine for ten minutes, shut OFF the engine and recheck the belt tension. Readjust if necessary.

Two popular methods of checking drive belt adjustment are; the Belt Tension Gauge Method and the Belt Deflection Method. The former requires a special gauge and the latter requires a straight edge and scale or just a good eye for measurement. The deflection method will be used in the following belt replacement instructions. A rule of thumb for checking belt tension by the deflection method is to determine the midpoint between two pulleys of the drive belt and press down at that point with moderate thumb pressure. The belt should deflect to the measurement indicated in the following installation procedures. Adjustment is necessary if the belt is either too loose or too tight.

WARNING A belt adjustment which is either too loose or too tight will eventually damage the accessory that belt is driving. A too loose adjustment allows free-play in the belt which could transfer a whipping motion or shock to the accessory drive pulley. Similarly, a belt which is too tight will preload the accessory bearings, leading to early failure.


REMOVAL & INSTALLATION

Steering wheel shakes when the Aircon unit is on but if the Aircon is off it seems okey. pls advised.


First, check the level of your power steering fluid and top up the level if low. Then adjust your serpentine belts. A loose belt may be causing the the steering wheel. To adjust your alternator belt . First , take off the negative battery cable so you do not blow an expensive fuse on the positive battery cable clamp. Facing the back of the car, reach UNDER the alternator and loosen the bolt on the bottom right side, now loosen the bolt on the adjuster block on top, you can now turn the adjuster bolt and move the alternator to change or adjust the belt.
To take off or adjust the steering pump belt on the front of the motor, you need to loosen the nut on the back side of the adjuster pulley (right side ,belt is on the left) . With the adjuster pulley loose , you can use the adjuster bolt to move the pulley forward and backward to adjust the steering pump belt tension
