Turn the ignition off. Raise and support the vehicle with the wheels off the ground. Turn wheels fully to left, add power steering fluid to the full cold mark on dipstick. Leave cap off. Turn wheels from side to side several times, but do not touch steering stops. Add fluid, if necessary, to maintain level at full cold mark.
Start engine. With the engine idling, rechecked fluid level. Add fluid, if necessary, to bring level to the full cold mark. Install cap. Return wheels to center position. Lower vehicle. Continue to run engine for 2 to 3 minutes. Road test vehicle. Check for leaks. Ensure fluid level is at full hot Mark when fluid stabilizes at operating temperature

The system will bleed out the air by turning the wheel all the way from one side to the other repeatedly, do this action at least 10 times to be sure all the air is remove from the hydraulic system. Be sure not to allow the fluid level to drop too low or air will get back into the system.

2001 chevy tahoe vacum hoeses for power steering


Hello! There are power steering fluid in/out hoses but no vacuum lines...It sounds as if the pump needs to be bled of air or the belt is loose...Belt should move about 1/2 to 3/4"...Bleeding is as follows...
Guru...saailer

    ImportantPower steering fluid level must be maintained throughout bleed procedure.
  1. Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.
  2. ImportantWith hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF. This will discharge the hydro-boost accumulator.
  3. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure:
  4. 2.1. Start the engine.2.2. Firmly apply the brake pedal 10-15 times.2.3. Turn the engine OFF.
  5. Raise the vehicle until the front wheels are off the ground. Refer to Lifting and Jacking the Vehicle in General Information.
  6. Key on engine OFF, turn the steering wheel from stop to stop 12 times.
  7. Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.
  8. Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid .
  9. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
  10. Verify the fluid level. Repeat the bleed procedure if necessary.

Where do u put the power steering fluid?


Hi.

Most Chevys have a reservoir under the hood. The reservoir is often near to engine oil reservoir. You will need to bleed the old fluid. This can be done using a siphon or disconnecting the pump return hose. Using the siphon from the reservoir cap is easier and safer.

Here the picture of the reservoir while bleeding with a siphon on a Blazer:

I WILL LIKE TO KNOW HOW CAN I REPLACE THE POWER STEERING PUMP ON A 2001 CHEVY MALIBU


1. Remove serpentine belt

2. loosen power steering pressure and return hoses

3. Remove nut from pressure line mounting on alternator bracket

4. remove power steering pump mounting bolts.

5. Lift pump assembly from engine mounting and remove hoses.

6. Reverse order to install. Fill and bleed system.

NOTE: A new or rebuilt power steering pump will most likely not come with a pulley attached. You will need a power steering pulley remover/installer tool to transfer the pully from the old pump to the new one.

Need to replace power steering pump. whats the step by step way to remove and reinstall


Remove the accessory drive belt from the pump
Remove the pressure hose from the pump
Remove the return hose from the pump
  • Remove the bolts from the pump.
  • Remove the power steering pump from the vehicle.
  • Remove the power steering pump pulley from the pump
  • Remove the reservoir from the pump



  • e649177.gif
  • Install the pump to the vehicle.
  • Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  • Install the power steering pump bolts.
  • Tighten
    Tighten the power steering pump bolts to 34 N·m (25 lb ft).
    Install the return hose to the pump.
    Then just reverse what you did to remove.
    Once you have it al back together fill the resevoir.
    Do not over fill
  • Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
  • Verify the fluid level. Repeat the bleed procedure if necessary
