A power steering pressure hose failure can be dramatic. Even a small hole in a pressure hose can cause power steering fluid to rapidly exit the system, usually landing all over something hot like an exhaust manifold or pipe. Combine this smoke show with a steering pump screeching from the sudden loss of fluid, and you might think world war three was commencing under the hood. Power steering system maintenance is the best way to avoid any smoke shows or sudden loss of power steering ability. The best time to replace a power steering pressure hose is before catastrophic failure. Monitoring fluid levels will provide an alert to power steering system leaks.

The system is fairly simple. A reservoir holds the power steering fluid. This reservoir can either be on the power steering pump or remotely located. The power steering pump is at the heart of the system. The pump itself takes power from the engine via an accessory belt. The pump pushes the fluid through a pressurized hose to the steering box or steering rack. Another hose brings the power steering fluid back to the reservoir once the power of pressure has been used to turn the wheels to and fro. In this way the show can go on and even the tiniest of humans can drive and parallel park an enormous vehicle without ending up with giant arms.

Here, the suggestion and definitive solution is to "change or replace" no "or patch to fix" some of these components.

Power Steering Pressure Hose Replace
* Where is all that power steering fluid going anyway? Inspect hoses and unions. Obvious leaking is easy to spot. Slower leaks are a bit trickier. Look for dirt gathered around one greasy spot.

* Determine which is the pressure hose and which is the return. The pressure hose will generally be the one that's leaking, and have threaded fittings on either end. The return hose will have hose clamps.

* Apply penetrating oil on the end fittings of the power steering pressure hose. These bolts have usually been in there for a while, and can be stubborn to remove.

* Place a drain or catch pan under the low point of the pressure hose. The law of gravity also applies to liquids. Use a flare nut wrench to break loose the hose fitting. Another trick is to use a plug on the hose end once removed to prevent leaking.

* Hose routing can either be simple or downright crafty. Remove and save all clamps and shields on the way to figuring it out. Loosen and remove the rack or steering box end of the power steering hose. Use a flare nut wrench! Chances of stripping the bolt are high with a standard box wrench.

* Tighten everything back up and add power steering fluid to the "cold" level in the reservoir. Start the vehicle and turn the wheel lock-to-lock a few times to bleed the system of air. Top off power steering fluid. Repeat until system is free of air.

Hope this help.

    Also, can try this guide about how to
    Make an Emergency Power Steering Hose Repair.

    Ever had a power steering hose spring a leak and
    you are in the middle of nowhere, there is a parts store but your part
    isn't available. I will show you a quick and easy way to repair a power
    steering hose (Difficulty: Moderately

    Things You'll Need:

    • Air hose spice kit

    • Heavy duty hose clamps

    • hand tools such as screwdrivers, 1/4 inch socket set and
      small wrenches

    • pocket knife

    • power steering fluid


    1. Determine leak location:
    You have established you do have a
    power steering hose leaking, you can turn the steering wheel with the
    engine running and power steering fluid will spray out the hole in the
    hose, you may need an assistant for that part. You may also need to jack
    up the vehicle to see where it is leaking from. Set parking brake and
    use blocks or jack stands for safety after lifting vehicle. You may have
    to add fluid to an empty power steering pump to locate the leak.

    2. After you have determined where the leak is,
    then remove the bad spot in the hose. I happened to do my emergency
    repair in front of a NAPA store, I bought the parts from there and the
    store owner was kind enough to loan me a few tools to get the job done.
    He had a hose cutter that worked great to cut off the bad hose. We kept
    the bad spot of the hose for a vacation souvenir. The picture shows what
    I used for parts.

    Install the hose clamps 2 on each
    side, and stagger them as shown in the picture. This allows you to get
    them closer together and have more clamping force on the splice. Slide
    in the brass coupling, install the hose clamps on the other end of the
    hose and slide the hose into the coupling. Make sure you slide it all
    the way on.

    Tighten the clamps as tight as you can get them without
    stripping the clamps out, put the hose back into position in the
    vehicle. Fill the power steering tank and recheck for leaks, if you have
    made a successful repair the power steering will work and you won't
    lose a drop of fluid.

    Good luck.

Power steering fluid leaking. change hose? change pump? Re clamp?

If the hose itself is leaking (not the connection/end) , replace the hose. If the hose is more than 5 years old, I'd probably just replace it. If it's the low pressure hose (return) and it's leaking at the junction, you can probably replace the clamp. If it's the high pressure hose (with the machine-formed hose ends) then replace the hose - a clamp is unlikely to withstand the pressure and you don't want to take the chance of it blowing off when you're turning.

How to repair power steering leak?

You need to first diagnose what is leaking. Most power steering leaks are in the pressure hose but not always. Pressure hoses will have screw on fittings and return hoses will usually just have spring clamps or screw type clamps on the end of the hose. Pressure hose most likely, return hoses 2nd, failing rack and pinion assy 3rd and pressure pump last. If its leaking from the bellows on the end of the rack and pinion the you will need a reman unit. Presure pumps are also remanufactured if thats what you need. hoses are replaced with new hoses or standard return hose for the return line.

I need the metal tube coming from the power sterring pump that connects from the top of the pump towards the bottom of the car.The fitting that goes into the top of the pump is leaking and doesn't appeare...

What You need is a power steering pressure hose assembly. NO! you cannot just replace it with a piece of rubber hose! That thing takes about 1200 PSI of pressure! The entire hose assembly from the pump to the steering gear is only about $20 and should be available at most any retail parts store.

High presure power steering hose is leaking

Hi, they do make a universal high pressure hose for your vehicle. You have to purchase the hose and the fittings seperately. It is made by Russell. The fitting choices are straight hose end, 45 degree hose end and 90 degree hose end. I found these parts at . The two fittings and hose will cost about $175 to $200. They ship to you for free. I hope this was helpful.

Power steering pressure hose leaking

If the hose is leaking at a fitting you can check to make sure it is tight. If it is leaking any other place or the fittings are tight you need to replace the hose and refill the fluid with new fluid.

When power steering hose replacement is required, follow these steps:
  1. With the engine stopped, remove the return hose at the power steering gear, and allow the fluid to drain from this hose into a drain pan. On some cars, the vehicle must be lifted on a hoist to replace the power steering hoses.
  2. Loosen and remove all hose fittings from the pump and steering gear.
  3. Remove all hose-to-chassis clips.
  4. Remove the hoses from the chassis, and cap the pump and steering fittings.
  5. If O-rings are used on the hose ends, install new O-rings. TRW steering gear cylinder lines have gaskets that are serviced as a unit. The old gasket must be pried out of the fittings in the housing before the new lines and gaskets are installed. Lubricate O-rings with power steering fluid.
  6. Reverse steps 1 through 4 to install the power steering hoses. Tighten all fittings to the manufacturer's specified torque. Be sure all hose-to-chassis clips are in place. Do not position hoses where they rub on other components.
  7. Fill the pump reservoir to the full mark with the manufacturer's recommended fluid. Bleed air from the power steering system. Check the fluid level in the reservoir and add fluid as required.
