In a hydraulic system, a power steering hose is used to transport hydraulic fluid from power steering pump to steering rack. And then back from the steering gear or rack to the fluid reservoir.
Sometimes, if these hoses are damaged or leak, they disturb your overall power steering system. That is why you need to pay attention to them instantly and avoid heavy loss. In this article, you will learn the complete method to replace power steering hose.
Power Steering Hose Replacement Process
If you notice that your steering wheel takes time to move or get hard. Plus, you observe a low fluid level, squealing sounds, burning smell, visible cracks and foamy steering fluid. These signs indicate that your power steering hose, pump, rack, belt and reservoir is leaking. To know the exact source of the leak or damage, inspect the components. After seeing them, you need to replace them immediately.
Is it hard to fix a power steering leak? Basically, it depends upon the problem that means leak is coming from which location and what component is defective. If there is an issue in your power steering hose, then you can follow below steps to replace it. One more thing you must remember, there will be specific procedures for every vehicle however, most are relatively similar.
1. Collect Equipment
Before you start, you have necessary tools which are based on your vehicles.
- Ratchet, torque wrench and flare nut wrench
- Socket set
- Pliers for hose clamps
- Flathead or philips screw drivers
- Catch basin
- Jack and jackstand
- Flash or torchlight
- New hose and its assembly
- Fresh hose compatible fluid (ATF, CHF)
- Shop rags or towels
- New hose clamps and O rings
- Hose gasket & sealing washer if needed
- Safety goggles and gloves
2. Prepare Your Vehicle
After collecting tools, you need to park your car on a plain surface. You must secure the back tires so it can’t roll and raise the front of the car from the ground with the help of jack. You can do this if access requires lifting. Also, keep the jack stand underneath for safety.
Then apply the parking brake, turn off the engine and disconnect the battery if needed. You need to wait and allow the engine to cool down, so you remain safe from steam and hot metal parts.
3. Locate and Analyze Hose
Now open the hood and try to locate the power steering hose. You need to see the symptoms such as cracks, splits, abrasion and soft spots. In this way, you will find defective hose. Additionally, you should check that the wear hose is a pressure steering hose or return hose. Because both have different requirements.
Generally, it connects from steering pump to gear or back from gear to reservoir. To find the actual hose, you have to trace the line from one point to another. Also confirm the exact source of the leak before untightening the bolts.
4. Drain Steering Fluid
At this moment, you should place the catch basin under your power steering system to capture the fluid from the hose. Then remove the cap from the power steering fluid reservoir. You can drain the fluid from the reservoir through detaching the hose or siphoning fluid for less mess. You may also use another method because it totally depends upon your vehicle design.
If you drain fluid with a hose, you need to loosen the clamps or connectors from one side. Our advice is to use shop towels to protect nearby components from power steering fluid. Once the fluid drains completely, you should dispose of it carefully. You can take it to a recycling or local service center following the regional laws or rules.
5. Loosen Fitting
You will notice fittings like clamps or other fasteners at the ends of hose that are used to secure it. To loosen them completely at both ends of the hose, you can use appropriate wrench or pliers. You can follow your vehicle service manual for this purpose. For instance, you can use a line or flare nut wrench, if you remove a high pressure hose at the pump.
In case you take out low-pressure hoses from the rack, you can use pliers, flat screwdriver or socket driver. You need to remove other components for access and must note the position of each fitting or clamp.
6. Now Remove Old Hose
After loosening the connectors, you should pull the hose gently. Along with fittings, you must notice how hoses are routed. So you can install your new hoses in the same way to prevent it from rubbing against other components. When you remove the hose, some residual fluid will drip out.
Therefore, you have rags to clean the surrounding area. Furthermore, you must cover the hole or tubes instantly on machinery or equipment that are temporarily disconnected during repair. As a result, dust and debris cannot go inside, which can cause damage.
7. Install New Hose
As you remove the old hose, then compare it with the new hose to confirm you have the right one. There will be sensors or other hardware that needs to be transferred between old and new power steering hose, so do that if needed. Now you should carefully route and reinstall new hoses. Make sure they are in the same orientation as the hoses you removed before attaching them.
After you install a new hose, connect the fitting at both ends and tight them to secure hoses according to manufacturer specifications. You should avoid the overtightening because it can damage the hose or its fitting. Moreover, you must inspect your clamps and fastener for rust or excessive wear. If they deteriorate, then also replace them and use a new one.
8. Refill the System and Remove Trapped Air
Now, you have to fill the power steering reservoir with fresh manufacturer recommended fluid up to the right line. In case you use the wrong type of fluid or overfill the reservoir. It will damage the seal, cause leak, noise, steering control and many other problems.
Next, turn the steering wheel lock to lock multiple times to push out air (bleed) with the engine off. Then start the engine and steer the steering wheel left and right several times to force the air bubble out of the system. Procedure of bleeding might vary by vehicle, therefore you can take help from your car service manual.
9. Finally Test Power Steering System
In the end, you should check the reservoir fluid level, if it is low then top of it. In addition, you must inspect all connections with a flashlight to make sure there is no new leak. You should verify one more time to observe the above mentioned signs. Plus the hose must remain away from contact with sharp edges. After that, replace the power steering cap, close the hood and remove the jack stand from the tire.
Furthermore, you should drive at low speed in a safe area to confirm that the steering wheel is working smoothly without any noise. If everything looks fine, then congrats, you successfully replace the power steering hose.
Signs You Need a Professional For Power Steering Hose Repair
You can call a professional if you don’t find a hose. In case you locate it but the hose cracked in such a way that it is stuck into the system due to rust fitting. As a result, you face difficulty accessing and remove it. Furthermore, if you are not sure about matching fluid type, torque specifications or how to bleed the system of your vehicle. Then you can consult a mechanic to get help.
Next, you try to replace it yourself and lastly test the system. And you still observe the same leaks, strange noise or feel a stiff sterling wheel. Along with them, you are not confident about your mechanic skills. We can say that you should take your vehicle to an automotive repair technician. Because he knows how to perform everything well.
How Long Can You Drive With a Power Steering Leak?
If your vehicle has very small power steering leaks, then you can drive several days or hundreds of miles. The condition is that you must regularly check the fluid and add more. In case, the power steering fluid leak is large and you continuously top off it but it is still low or drains out. You cannot drive even a few miles.
In addition, your vehicle power steering pump and rack start overheating which leads to an entire system failure without fluid. Further, some research shows that you can drive around 400 miles if you replenish the fluid in time before driving. However, this approach works temporarily and is unsustainable for lasting strategies. In short, it is based on the severity of leak, how often fluid is replenished and run out, driving or road conditions.
Power Steering Hose Replacement Cost
Generally, the replacement cost of a power steering hose is around 200$ to $500 for most vehicles. The reason is that a professional technician can charge you for his labour and additional parts. If you replace it yourself, then you have to pay for the hose and components only. In this way, you can save your money on labour.
| Components | Replacement cost |
