Power steering fluid ejects from pump when vehicle is turned off why?

Disconnect the return line from the pump and let it hang into a drain container. Start the vehicle and turn the wheel, this will evacuate old fluid into container. Stop engine and fill the reservoir with new fluid and repeat, this will flush the system. Reconnect the return line to the pump and add new fluid. Start the vehicle and turn the wheel slowly until its easy to turn and you don't hear any noise from the pump; this evacuates any air from the 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 would drain your power steering pump, even if I had to take it off and dump the fluid! Yes, you do need to use power steering fluid, but what will get you in the most trouble is if you mix your fluids because then they work against each other.

While some people will use transmission fluid in a power steering pump in an emergency, I always recommend they drain it out and use the proper fluid in the proper place.

Fig. Fig. 2: Power steering pump mounting-early model vehicle shown

Fig. Fig. 3: Power steering pump mounting-late model vehicle shown

1. Installation is the reverse of the removal procedure. Tighten the pump mounting bolts to 18 ft. lbs. (25 Nm).
2. Bleed the power steering system to remove trapped air. Air in the system could cause noise and or damage to the pump.

BLEEDING

This procedure requires the help of an assistant.

1. With the engine OFF, the wheels off the ground and turned all the way to the left, fill the fluid reservoir to the FULL COLD mark on the fluid level indicator.
2. With an assistant checking the fluid level and condition, bleed the system by turning the wheels from side to side without hitting the stops. You should repeat this at least 20 times, making sure to keep the fluid level at the FULL COLD mark.

Fluid with air in it has a light tan appearance. This air must be eliminated from the fluid before normal steering action can be obtained.
See Figure 4

Fig. Fig. 4: Power steering bleeding procedure

1. Start the engine, and while it is idling, recheck the fluid level and add as necessary to reach the FULL COLD mark.
2. Return the wheels to the center position. Lower the front wheels to the ground and continue running the engine for 2 or 3 minutes.
3. Road test the vehicle to make sure the steering functions properly and is free of noises.

Follow this steps

The items you will need include basic hand tools, shop rags, gloves, drip pan, fluid suction gun, power steering pump pulley removal tool, power steering pump pulley installation tool, power steering fluid, and a Haynes manual.

Use a suction gun to remove the power steering fluid.

Position a drip pan under the pump and disconnect the high pressure line and fluid return hose. Cap the ends of the lines.

Loosen the serpentine belt and slip it out of the power steering pump pulley. Replace any worn belts at this time.

Remove the bolts and nuts that hold the pump onto the engine.

Remove the pump. Now remove the pulley from the pump. To do this, use a power steering pump pulley removal tool. If you don't have one, you can rent one from Advance Auto Parts.

Remove the nuts to detach the pump from the brackets.

Reattach the bracket to the new pump. Reinstall the pulley.

Bolt the pump back into place. Slip the belt back onto the pulley and retighten. Reattach the high pressure line and return fluid hose.

Now fill the power steering fluid reservoir until it reaches to the proper level. Now start the vehicle. Recheck the fluid and add if necessary. Turn the wheels left and right a couple of times. So that's it, you are done. Test the vehicle to make sure it functions properly.

Your problem could be a pressure side hose that has a rupture that only leaks in extreme conditions. Inspect to replace with new to repair problem. First make sure you have removed the pump caps off of the hose fittings. If ok, it appears you may have a stuck valve in the rack assembly. Replacing the rack should solve your problem. ------- The new pump should be self-bleeding by turning the wheels left and right. Let sit over night to release air bubbles, recheck fluid level.------ Check the tension of the drive belts on the pump, as they may be loose. The power steering pump and reservoir is located on the front of the engine driven by one of the fan belts. There is a removable cap on the top with a dipstick attached. With the engine off, fill this up to the full mark with power steering fluid. Replace the cap, start the engine and check for leaks. On the back of the pump are two hoses either one could be leaking. REPAIR PROCEDURE:
1. Wipe the power steering cap and area free of dirt. Remove the power steering cap.

2. Use a siphon pump to remove as much fluid as possible from the power steering fluid reservoir.

3. With a helper in the vehicle, raise the vehicle on an appropriate hoist.

WARNING :POWER STEERING FLUID, ENGINE PARTS, AND THE EXHAUST SYSTEM MAY BE EXTREMELY HOT IF THE ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES OR POWER STEERING FLUID TO TOUCH HOT EXHAUST MANI FOLD OR CATALYST. 4. Locate the power steering cooler attached to the crossmember support plate. Slide back the clamp and disconnect one of the two power steering return hoses at the power steering oil cooler and drain fluid in an appropriate container.
5. Have the helper turn the steering wheel back and forth quickly several times to force as much fluid as possible from the steering gear.
6. Reconnect the hose at the oil cooler using the original clamp.
7. Lower vehicle so the vehicle tires are not contacting the ground. 9. For proper fluid fill and bleeding air from the power steering system:

a. Fill the power steering reservoir to the top of the fill range using Mopar power steering fluid (ATF+4) p/n 05013458AA.

b. With the engine OFF and the vehicles tires off the ground, slowly turn the steering wheel back and forth (lock to lock) slowly 20 times to force fluid into the steering gear.

c. Fill the power steering reservoir to the top of the fill range.

d. Start engine and let run for a few seconds, then turn oft engine.

e. Check fluid level and add if necessary.

f. Start engine, and slowly turn the steering wheel lightly contacting the left and right stops.

g. Stop the engine and check fluid level. Add fluid if necessary.

h. Lower vehicle, start engine and slowly turn steering wheel lock-to-lock.

I. Stop engine and check fluid level. Add fluid if necessary.

j. If fluid is extremely foamy, allow vehicle to stabilize a few minutes, then repeat steps "i" and "j" until the fluid level remains constant after running the engine and turning the steering wheel from lock to lock.

10. Inform the vehicle owner/operator that a steering vibration may be noted for a few hundred miles until the air is completely removed from the steering system. This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

Problems associated with low power steering fluid…

Hard Vehicle Steering
A low power steering fluid level can often times cause a vehicle's steering to become hard and labored. Adequate amounts of power steering fluid are necessary to enable a vehicle's power steering system to function and operate at optimum levels. A lack of power steering fluid in a vehicle's power steering system reduces the amount of hydraulic fluid pressure necessary to efficiently operating the various parts of the entire power steering system. Power steering fluid supplies the fluid force needed to operate the power steering gears and to enable power steering gearbox operation. Low power steering fluid levels reduce this hydraulic pressure, which commonly results in hard vehicle steering.

Pump Noise
It is very common for a low power steering fluid level to cause significant power steering pump noise. An adequate amount of power steering fluid is required to ensure the proper function and longevity of a power steering pump unit, which is a belt-driven pump responsible for housing and circulating power steering pump fluid. A low level of power steering fluid results in increased power steering pump friction, heat, and wear, all of which can significantly reduce the operational life of the power steering pump while at the same time cause excessive power steering pump noise.

Fluid Boiling
Many times a low power steering fluid level can result in excessive heating of power steering fluid, a condition that can seriously degrade the fluid and cause it to boil. A low power steering fluid level results in less available fluid to both lubricate and cool a power steering pump unit. A lack of power steering pump lubrication and cooling leads to excessive heat being generated within the power steering pump unit itself, a condition that translates into the available level of power steering fluid becoming super-heated and degraded. When this happens it is common for the power steering fluid to boil and lose all of its lubricating and heat-reducing capabilities.

Gearbox Wear
The power steering gearbox is a set of gears within a vehicle's power steering system designed to facilitate movement of a vehicle's front wheels. The power steering gearbox is connected to the power steering pump by hydraulic fluid lines that deliver a constant supply of power steering fluid to the power steering gearbox. A low power steering fluid level, especially a chronic and severe low power steering fluid level, can lead to increased friction and wear within the power steering gearbox assembly, a condition that can significantly shorten the operational life of the power steering gearbox and negatively affect its operation

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

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

check to see if you have power steering fluid. if your low fill it up. (most cases thats all it is) check around for any leaks or parts to the power steering unit for and damage (hoses, pump, rer, rack and pinion, any seals or such. you might have a leak somewhere. when your looking for leaks fill the res up with power steering fluid. turn the car on. and have someone turn the wheel so get the fluid to build up pressure in the system.
