There are so many cars out there that your question most likley will not get an exact answer. It will be anywhere between a 12mm to 16mm. The problem you will run into is the pully will need to be removed once the unit is off. This takes a special puller and installer. Best bet at this point is to have a shop swap out the pully for you rather than buying the tool.

2001 Cadillac sls power steering hose replacement

You have to get an 18mm tubing wrench to remove the lower connection of the pressure hose from the power rack under the car. This size tubing wrench is not a "typical" size wrench when you purchase a tubing wrench pack. Remove all clamps and then snake the hose out from the top.

How to change power stering pump on 1995 Chevrolet1500 2wd with 350ci with air conditioner

  1. Lift the hood. Remove the power-steering cap. Use the turkey baster to siphon as much fluid as possible from the power-steering pump reservoir. This is done to lessen the fluid loss when the hoses are removed.

  2. 2

    Remove the two pressure hoses from the rear of the power-steering pump, using a wrench and common screwdriver. The high-pressure hose is threaded into the back of the pump while the lower-pressure hose is held on with a clamp.

  3. 3

    Loosen the belt tensioner by using a wrench to move the tensioner away from the belt and removing the belt.

  4. 4

    Place the power-steering pulley extractor tool on the nose of the pulley. The tool has two half shells that clamp around the lip on the nose of the pulley and around the lip of the tool. Thread the tool in until the shells fit on both the pulley and the tool lip. Install the circular metal band to keep the shells in place. Hold the threaded head of the tool with a wrench. With another appropriately sized wrench, turn the large nut above the shells counterclockwise to pull the pulley off.

  5. 5

    Remove the bolts securing the pump to the support bracket. Remove the pump.

  6. 6

    Install the new pump. Insert the securing bolts and tighten. Install the pulley by holding the pulley on the shaft while threading the extractor tool into the center hole of the shaft, with the shells removed. Hold the head of the threaded shaft with one wrench and turn the large nut clockwise with another wrench to push the pulley on the power-steering pump shaft.

  7. 7

    Install the serpentine belt by pushing the tensioner away from the belt while wrapping the belt around the pulleys. Allow the tensioner to press on the belt, causing tension.

  8. 8

    Install the two power-steering hoses. Fill the power-steering pump reservoir with power-steering fluid. Start the truck and turn the steering wheel lock-to-lock, left and right several times to bleed all the air from the system. Check the fluid one more time.

My jeep grand cheorkee has no power steering at all when i went to get my serpentine belt replaced thats when my power steering went can you tell me how to check if my power steering pump went or i might...

Fill is on the left (drivers side) of the unit. Drain is usually on the bottom but some are on the passenger side near the bottom. Both are usually normal wrench size, though I've seen some that use a star wrench or some that have been replaced with a hex female plug. Open the fill plug first because if that one is frozen and you drain it, you won't be able to re-fill.

Welcome to Fixya

here's the procedure on how to replace water pump of your car

  • 1 Turn the belt tensioner pulley counterclockwise on the 3.4L modeal. Use a breaker bar and a socket to rotate the center bolt on the tensioner pulley. If you have a 3.5L engine model, turn the pulley clockwise.

  • 2 Slide the drive belt off the steering pump pulley.
  • 3 Detach the black ground cable from the battery using a wrench.
  • 4 Position a drain pan under the car in the direction of the steering pump hoses.
  • 5 Move any wire brackets near the steering pump out of the way using a wrench or ratchet and socket, if necessary.
  • 6 Disconnect the return hose from the power steering pump by loosening the clamp at the steering pump using a ratchet and socket. Then pull the hose off the pump and let the steering fluid drain into the pan.
  • 7 Detach the pressure hose from the steering pump by unscrewing the retaining nut at the pump using a tube wrench. Let the steering fluid drain on the pan.
  • 8 Unscrew the steering-pump mounting bolts using a ratchet, ratchet extension and socket.
  • 9 Lift the power steering pump off the engine compartment.
  • Install the New Steering Pump
  • 1 Position the new steering pump in place and start the mounting bolts by hand. Then tighten the bolts using the ratchet, ratchet extension and socket.
  • 2 Attach the pressure hose to the steering pump by starting the retaining nut by hand. Then tighten the nut using the tube wrench.
  • 3 Connect the return hose to the steering pump. Then tighten the clamp using the ratchet and socket.
  • 4 Reinstall any wire brackets you had to remove using a wrench or ratchet and socket.
  • 5 Connect the black ground cable to the battery using a wrench.
  • 6 Install the drive belt by turning the tensioner pulley counterclockwise using the breaker bar and socket. Then slide the belt over the steering pump pulley. If you have the Aztek 3.5L engine, turn the tensioner pulley clockwise.
  • 7 Reinstall any wire brackets you had to remove form near the steering pump using the wrench or ratchet and socket.
  • 8 Connect the black, ground cable to the battery using a wrench.
  • Bleed the Power Steering System
  • 1 Refill the steering fluid reservoir with new steering fluid. Make sure the level reaches the Full Cold mark on the reservoir.
  • 2 Raise the front of the vehicle using a floor jack until the front tires are off the ground. Then support the car on 2 jack stands.
  • 3 Turn the ignition key to the On position but do not start the engine.
  • 4 Turn the steering wheel fully from left to right 15 times.
  • 5 Check the fluid level in the steering reservoir and add if necessary.
  • 6 Lower the vehicle and start the engine. Turn the steering wheel and listen for steering noises. If you hear noises while turning the steering wheel, repeat steps 2 through 5 of the bleeding procedure to get rid of the air in the steering system. Turn off the engine.

    Replace power steering pump on 1995 K1500 silverado pickup. The rubber portion of one of the fluid lines has a pin-size hole and sprays fluid out when engine is running and steering wheel is turned.

    You must replace the line. Holes in the lines can not be patched. The pump would not be the problem, if it was the whole line would blow apart.

    Power Steering Pump

    Lift the Vehicle
    Remove the Serpentine Belt
    Remove the Air Cleaner Assembly
    Remove the Two Power Steering Hoses.  The one on the Top have a Band on them.  use Pliers to remove the Band.  Then remove the hose.  Make sure you have something to catch the oil.

    Next Remove the lower Hose with a Wrench (not sure on size)
    There are three bolts that connect the PS pump to the block.  The easiest way is to go between the Air Cleaner Assembly and the Fuel System to get to the three bolts.  I think they were 13 mm socket.  You will need a deep well and a short socket wrench will work best.  This is a very tight fit so good luck, expect scars and make sure the Engine is cool.
