The power steering on my F250 does not work. I removed the pump, and it seems to work on the bemch - I can't keep my finger on the delivery side of the pump on the bench. Is the system pependant on volume and pressure, or could the problem be with the steering box?

I would avoid that entire dilemma by just taking out the whole ps pump and replacing the pulley then, seems like a lot of work but it's worth it cuz the radiator removal is way more involved and more likely to cause problems with antifreeze leaks, also you probably only have to tilt the PS pump to get the pulley off so I would not disconnect the power steering hoses until I absolutely had to

before start job suction out power steering fluid out of pump using large sirenge or siphon pump then.you need a table vise and two pieces of wood.okay to remove power steering pump. you need to disconnect the ground cable.remove air intake duct.remove the pulley cover.remove the drive belt.disconnect power steering pump switch connector.disconnect the pressure hose and the suction hose from the power steering pump.cover power steering hose and pipe keep getting trash dirt and debris.remove the installation bolt of the power steering pump bracket.place the oil pump bracket in a vise btween two pieces of wood keep from damaging bracket and remove the two bolts from the front side of the pump.remove bolt from rear side of the oil pump.disassemble the oil pump and the bracket by inserting flat tip screw driver.to install tighten oil pump to bracket bolts 12 ft lbs. tighten the bolt from the rear side of the oil pump to 27 ft lbs.tighten steering hose eye bolts to 30 ft lbs.replace fluid bleed air out power steering system.

Hi there:
Check this procedure on 2.5L (VIN N) Engine...

1. Disconnect the negative battery cable.
2. Remove the right side under cover.
3. Remove the speed control vacuum reservoir and related components as required for alternator access.
4. Remove the power steering pump cover.
5. Remove the A/C compressor drive belt.
6. Remove the alternator/power steering pump drive belt.
7. Remove the intake manifold plenum.
8. Remove the upper alternator bracket.
9. Remove the intake manifold plenum stay.
10. Detach the electrical connections at the alternator.
11. Unfasten the upper and lower bolts and remove the alternator. Be very careful not to damage neighboring components while removing the alternator.

To install:

1. Connect the wiring to the alternator.
2. Place the alternator on its lower bracket and install the upper and lower bolts finger-tight.
3. Install the upper alternator bracket.
4. Install the alternator/power steering pump belt, making sure it is properly seated.
5. Adjust the drive belt to the correct tension using the belt adjuster, then tighten the upper mounting bolt to 16 ft. lbs. (22 Nm) and the lower mounting bolt to 30 ft. lbs. (41 Nm).
6. Install the intake manifold plenum.
7. Install the intake manifold plenum stay.
8. Install the A/C compressor drive belt.
9. Install the power steering pump cover.
10. Connect the negative battery cable.
11. Check the charging system operation.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Hmm.. Low fluid in the power steering pump, broken belt driving the power steering pump, failed component causing loss of power steering fluid, failed power steering pump.

Check for a broken belt first, check the oil in the pump, look for leakage under the truck.

If the pump is low on fluid you want to put about half the amount in that you're going to need and then start the truck and turn the wheel slowly from stop to stop, each way- spend about ten seconds going from one stop to the other. This will allow any air in the system to be purged out in a controlled fashion, it can really spray if you get a big, compressed bubble of air in the system and release it quickly. Shut the truck off and top the steering pump up, check for leaks.

The procedure is as follows:--- 1) Locate the power steering pump on the driver's side of the motor, which is mounted in front of the engine, near the top.2) You will see a fill spout coming out of the pump with a cap on it that says "power steering fluid."
3) Remove the negative battery cable from the battery
4) Remove the cap from the power steering pump,allow the fluid to drain into the pan.
5) Loosen the bolts that hold the power steering pump to the engine block with a socket wrench. Once the pump is loose, remove the belt from the pulley on the power steering pump. Remove the pump from the engine compartment.
6) Insert new power steering pump in reverse. 7) Reattach the power steering hoses and verify they are secure. Fill the new power steering pump with fluid to the full line shown on the dipstick on the back of the cap for your power steering pump. Place the cap back on the power steering pump.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

Hi I just thought you might like to know that the VSS sensor(vehical speed sensor) on a 93 f250 is actually on the top center of the rear differential. It is basically a proximity type sensor not the old school gear and cable. It will take a 1/2" or 13mm wrench I believe to remove the single bolt holding it in and the it pulls out. I think they are around 25 bucks so it's cheap enough to fix the speed sensor.

Hello hummelsautob.
Changing the power steering cooler can't allow air into the brake system. Two different fluid systems.
Your F250 has it's brake assist powered by the power steering pump.
Instead of using a vacuum assist it uses the hydraulic power from the pump.
When refilling your pump you have gotten air mixed in with the fluid. This turns it into a consistency something like whipped cream.
When in this state it isn't effective. Let it sit for a couple hours and let the air bubble out of the fluid. Recheck your level after this as it will drop.
This will make your brakes feel normal again.
Just a note on adding fluid to an empty power steering pump.
Add fluid to the reservoir but not to the top, turn the steering wheel back and forth slowly with the engine off. This will keep the fluid from foaming.

Notes Power steering pump, replacing

Note: As the illustrations in this service information are used for different model years and/or models, some variation may occur. However, the essential information in the illustrations is always correct.

Preparation

Warning: Used fluid is considerably more dangerous than new fluid. Avoid skin contact with the oil.

Remove

• the oil hose from the mounting on top of the power steering pump
• the auxiliaries belt.

Note: If there is dirt in the fluid, drain the system and remove the hoses from the steering gear.

Removing the power steering pump/engine strut
Applies only to diesel cars:

Remove

• the screw at the pump
• the screw at the engine.

Leave the strut hanging in the delivery line.

Removing the feeder hose and delivery line
Install

• the lock grip pliers on the feeder hose as close to the power steering pump as possible
• the lock grip pliers on the return hose at the fluid reservoir.

Note: Place paper over the generator (GEN) as protection against oil.

Remove

• the screw nipple. Remove the delivery line from the pump
• the hose clamp. Remove the feeder hose from the power steering pump.

Warning: Avoid skin contact with the oil.

Removing the power steering pump
Remove

• the 3 screws
• the servo pump.

Installing the power steering pump
Install

• the servo pump
• the three screws. Tighten to 25 Nm .

Installing the power steering pump
Install

• the feeder hose. Tighten the clamp
• the delivery line. Do not tighten yet.

Installing the power steering pump/engine strut
Applies only to diesel cars:

Install

• the strut
• the screw at the engine. Tighten to 24 Nm
• the screw at the pump. Tighten to 24 Nm .

Finishing
Tighten the delivery line. Tighten to 25 Nm .
Remove paper and lock grip pliers.
Install the auxiliaries belt.

Try filling the P/S pump resevour and slightly turning the steering wheel side to side just enough to activate the P/S pump. Remove the return line from the pump and keep turning the wheel until you have a really good flow out. Be sure to keep adding P/S fluid while you're doing this. If it's still hard to steer, the pump bearings are now bad. Time to replace it.
