What bolts do I loosen to tighten the power sterring belt on my 1981 buick reveria

1. From the top of the vehicle loosen pivot bolt Power Steering Belt Adjustment
2. From under the vehicle loosen the locking bolts F and G
3. Install the belt. Adjust belt tension with 1/2 in. breaker bar installed in adjusting bracket Power Steering Belt Adjustment
4. Tighten locking bolt G to 28 N·m (250 in. lbs.)
5. Tighten locking bolt F and the pivot bolt to 54 N·m (40 ft. lbs.)

its like the old gm top bolt loosen and the bottom bolt loosen then in the back of the pump you can pry with a bar or if the bolt is there you tighten it in to tighten the belt then you tighten all the other bolts after the belt is tight

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.

ALTERNATOR AND A/C COMPRESSOR

1. Disconnect the negative battery cable.

CAUTION Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.

1. Raise and safely support the vehicle and remove the front undercover.
2. Loosen the tension pulley fixing nut and relieve the tension on the belt by turning the adjusting bolt.
3. Remove the belt.

To install:

1. Install the belt on the crankshaft and alternator pulleys.
2. Using the adjusting bolt on the tensioner, tighten the belt to the desired tension.
3. Tighten the fixing nut to hold the adjustment.
4. Install the undercover and lower the vehicle to the floor.
5. Connect the negative battery cable.

POWER STEERING BELT

1. Disconnect the negative battery cable.

CAUTION Wait at least 90 seconds after the negative battery cable is disconnected to prevent possible deployment of the air bag.

1. Raise and safely support the vehicle and remove the undercover.
2. Remove the alternator and A/C compressor belt.
3. Lower the vehicle and remove the cruise control pump link assembly.
4. Place the power steering hose under the oil reservoir.
5. Loosen the tension pulley fixing bolts and remove the power steering pump drive belt.

To install:

1. Install the power steering pump drive belt.
2. Insert an extension bar or equivalent into the opening at the end of the tension pulley bracket and pivot the pulley to apply tension to the belt.
3. Tighten the fixing bolts.
4. Raise the vehicle and install the alternator and A/C compressor belt.
5. Install the undercover and lower the vehicle.
6. Connect the negative battery cable.

3.0L SOHC Diamante

1. Disconnect the negative battery cable.
2. Loosen the lockbolt on the face of the A/C tensioner pulley.
3. Turn the adjusting bolt of the A/C tensioner pulley to loosen the tension of the A/C belt.
4. Remove the A/C compressor belt.
5. Loosen the locknut on the face of the power steering/alternator tensioner pulley.
6. Turn the adjusting bolt of the tensioner pulley to loosen the tension of the belt.
7. Remove the power steering/alternator belt.

To install:

1. Install the power steering/alternator belt first and then the A/C compressor drive belt.
2. Adjust the belts to the proper tension by turning the adjusting bolts and tighten pulley fixing nut/bolt.
3. Tighten the mounting nut of the power steering/alternator tensioner pulley to 36 ft. lbs. (50 Nm).

The idler belt can be loosed out on the main pulley circuit which allows the belt to be pushed into the slot and then the idler can be pulled up to be tightened to the desired tension.

ALTERNATOR/WATER PUMP DRIVE BELT(courtesy of autozone)

On most of the 1981-88 model year engines covered in this information, the alternator/water pump drive belt is tensioned by a screw type tensioner, which makes precise tension adjustment easy.

1. On 1981-87 models, loosen the locknut, located on the locking screw or lockbolt-located in a slotted portion of the outboard alternator mounting bracket.
2. On 1988 models, loosen the T-bolt, located in the center of the disc shaped portion of the outboard alternator bracket.
3. Tighten or loosen the drive belt tensioning bolt. This bolt is tightened to increase belt tension and loosened to decrease it.
4. When the belt tension is correct, tighten the lockbolt.

this is the 2.2 gas engine, if its different here is a link to the info at autozone

to tighten the thin belt, loosen the top and then the bottom nuts that go through to the frame. The turn the bolt on top, the closest to the front of the car, clockwise. Then tighten both through bolts up. For the thick belt, loosen the through bolt on the alternator, then turn the long bolt at the bottom, front of car, of alternator clockwise.

in order to do this on the power steering pump you have to loosen a few bolts to let it pivot on the top bolt in the front, then on the bottom on there is an adjustment bolt try to mark where that is tightened to with some electrical tape and then loosen it until the belt can be removed. put the replacement belt on the jeep in the exact same way the older belt was on and then tighten the adjustment bolt on the power steering pump until where you marked it where it was previously tightened to. then tighten the rest of the bolts you loosened and try to start it up. Have Fun.

if its a serpentine belt, diagram is on radiator support next to latch.if single belt, loosen pivot bolt and adjuster bolt on pump untill belt will slip on.you might have a tensioner (a pulley that looks like it does nothing)find a socket that fits center bolt and pull back to release tension,after getting belt aligned and on all pulleys let go of tensioner and spring load will take care off the rest.
