Am replacing power steering pump. Need to know procedure for bleeding fluid from lines and diagram for serpentine belt configuration.

I just finished replacing mine.

It is much easier if you do these steps:

1. Remove the serpentine belt.
2. Remove the nuts holding the main fuse box over the battery.
3. Remove the reinforcing bar over the battery.
4. Remove the battery.
5. Remove the windsheild washer tank.
6. Now you have access to remove the pump pulley. Without removing the stuff, it may be possible, but it will be extremely difficult.
7. Remove the pump pulley.
8. Loosen the high pressure hose fitting.
9. Remove the return line clamp.
10. Remove the power steering pump mounting bolts.
11. Remove the high pressure hose fitting.
12. Remove the power steering pump while sliding off the low pressure hose.
13. Remove the clips holding the reservoir on the pump.
14. Remove the reservoir.
15. Install new o-ring on the reservoir.
16. Install reservoir on new pump.
17. Install clips to hold reservoir on pump.
18. Install new o-ring on high pressure fitting.
19. Place new pump in position while sliding on low pressure hose.
20. Loosely attache high pressure fitting.
21. Tighten pump to mounts.
22. Tighten high pressure fitting.
23. Install clamp on low pressure hose.
24. Install power steering pulley.
25. Install washer reservoir.
26. Install battery.
27. Install reinforcing cross member.
28. Install fuse panel.
29. Install serpentine belt.
30. Bleed the power steering system.

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...

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.
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.

2. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure:
2.1. Start the engine.2.2. Firmly apply the brake pedal 10-15 times.2.3. Turn the engine OFF.
3. Raise the vehicle until the front wheels are off the ground. Refer to Lifting and Jacking the Vehicle in General Information.
4. Key on engine OFF, turn the steering wheel from stop to stop 12 times.
Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.

5. Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid .
6. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
7. Verify the fluid level. Repeat the bleed procedure if necessary.

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

first you need to remove power steering pump drive belt and fluid using a large syringe or siphon pump.then you need place drain pan under vechicle where power steering pump located,remove power steering return line and remove power steering pressure hose using a flare nut wrench,make sure drain pan catch power steering fluid. once you have the power steering pump return hose and pressure hose remove,then remove power steering pump mounting bolts then remove power steering pump.take old power steering pump and new power steering pump to machine shop or garage so they can transfer drive pulley from old power steering pump to the new pump,once you have new power steering pump ready to install be sure to buy new pressure hose o ring if equipped, you need to bleed power steering system once you have new pump in place with every thing back in place cant give you bleeding procedure you did not tell me vechicle type you working on.

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:

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.

there is no special procedure to replacing the pump.loosen the bolts on the front of the pulley before you remove the belt,remove the belt,lines,then the pump.fill fluid and turn the wheel back and forth to bleed the air out.after the air is out and the steering is not making any more noise top off the fluid

REMOVAL & INSTALLATION 2.4L Engine Fig. 1: Location of the power steering pump - 2.4L engine

5. Remove coolant recovery bottle as necessary.
6. Remove pump assembly.
7. Transfer pulley as necessary.
8. Reverse procedure to install, them bleed power steering system as follows:

1. Turn wheels all the way to left.
2. Add power steering to Cold mark on fluid level indicator.
3. Start engine and run at fast idle, then add fluid, if necessary, to bring level to Cold mark.
4. Bleed system by turning wheels from side to side without hitting stops. Keep fluid level at Cold mark.
5. Return wheels to center position and continue running engine for 2-3 minutes.
6. Road test vehicle to ensure steering functions normally and is free of noise.
7. Check fluid level and ensure level is at Hot mark after system has stabilized at its normal operating temperature.

Remove the accessory drive belt from the pump
Remove the pressure 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

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
