Power steering pump pulley removal 1996 buick riviera

If it’s the high pressure side then it will have metal connections on both ends. The rubber hose is the low pressure side. Follow the hose with the metal ends and you’ll find your answer

The pump pulley is pressed onto the pump shaft.
What are you trying to do ?

YOU NEED A PULLEY PULLER TO PRESS THE PULLEY OFF. I NORMALLY JUST UNBOLT THE POWER STEERING PUMP ITS EASIER. THERE ARE 3 10MM BOLTS THAT HOLD IT ON.

The following procedure requires the use of the GM Puller tool No. J-29785-A (1985-92), Puller J-25034-B (1993-96) or equivalent, and the GM Pulley Installer tool No. J-25033-B or equivalent.

1. Disconnect the negative battery cable for safety.
2. For 1996 vehicles, remove the air cleaner assembly for access.
3. For 1993-96 vehicles, remove the hood latch and the upper fan shroud.
4. Release tension and remove the drive belt.
5. Remove the power steering pump pulley using a suitable puller tool.
6. Remove the power steering pump retaining bolts, then reposition the pump as necessary for access to the hoses.
7. Position a fluid catch pan under the power steering pump.
8. Remove the hoses from the power steering pump and drain the excess fluid into the catch pan.

WARNING Be sure to cap all openings in the pump hydraulic system to prevent excessive fluid spillage and the possibility of system contamination.

1. Remove the power steering pump from the vehicle.
   

To install:

1. Position the pump to the vehicle, then uncap and connect the pump hoses.
2. Install the steering pump to the retaining bracket, then secure using the retaining bolts. Tighten the power steering pump-to-bracket bolts to 37 ft. lbs. (50 Nm). For 1996 vehicles, tighten the nut to 30 ft. lbs. (41 Nm).
   

On early-model vehicles where the drive belt is tensioned by pivoting the power steering pump assembly, do NOT fully tighten the mounting bolts at this time, since you will just have to loosen them again for belt installation and adjustment.

1. Install the pump pulley using the GM Pulley Installer tool No. J-25033-B or equivalent. Press the drive pulley onto the power steering pump.
2. Hand-tighten the pivot bolt, the adjusting bolt and the washer.
3. Install the drive belt. On early-model vehicles so equipped, properly adjust the belt tension. For details on belt installation and tension adjustment.
4. For 1993-96 vehicles install the upper fan shroud and the hood latch assembly.
5. For 1996 vehicles, install the air cleaner assembly.
6. Connect the negative battery cable.
7. Refill the power steering reservoir and bleed the power steering system.
8. Remove the jackstands and carefully lower the vehicle.
9. Road test the vehicle, then check and top-off the power steering fluid.

hope this help (remember rated this post) Good luck.

With a special tool called a power steering pulley puller. You can borrow this from some auto stores.

Not too bad. Loosen water pump pulley bolts then remove belt. Remove pulley and remove all of the pump bolts.

Place Jack under engine with wood to hold it up. Remove uper engine mount(leave loose in engine compartment. Loosen pulley bolts. Remove belts. Remove alternator bolts and lift out of the way for easy access to power steering bolts. Remove 2 power steering bolts using access holes in pulley. You should be able to accessall of the water pump bolts now by moving things out of the way as you go. The two larger bolts toward the radiator can be accessed through the two holes in the motor mount ( you will need a short socket on a 1/4" drive rachet). You should be able to get the pump off now. Installation is much easier than removal.

The power steering pump is only held on by two bolts that are removed thru the pulley holes. Anyway you don't have to remove the whole motor mount just remove the nut that holds the mount just to the left of the balancer. then remove the stud with a inverted torx bit. then remove the sleeve the stud went thru and then the belt will come off.

there are two bolts that hold the power steering pump in place that are accesable through the holes in the pulley. If you use a 6" extension and a 1/2" socket you can reach them. this will allow the pump to be removed and hang by the hoses and be out of the way. I was told also to inspect the cam sensor while it is apart because you have to remove the water pump in order to get to it.
