The power steering hose connects the power steering pump to the cylinders that enables a vehicle to turn left and right easily. Also known as the power steering pump or PS pump, it takes a pressurized power steering fluid right into the steering rack and uses it to control a steering wheel's rate of turn.
Aside from its use in power steering lines, it is also being utilized in hydraulics, air, fuel and lubricating oil applications. It contains resistant fabric cover and a patented synthetic rubber tube and is outfitted with standard steel reusable fittings. A hydraulic pump driven by a belt from a crankshaft pulley to provide up to 1,300 psi (8,964kPa) of "boost" pressure needed to operate the power-steering system.
The power steering systems are made up of two hoses - a high-pressure hose and a low-pressure hose. Made up of a reinforced synthetic compound, the high-pressure hose have hose fittings that are usually double-flared compression fittings while the low-pressure hose may not use compression fittings due to the lesser amount of pressure that passes through it. Additionally, the high-pressure (supply) hose carries high-pressure oil from the power steering pump to the steering gear and the low-pressure (return) hose brings oil from the steering gear back to the pump or its reservoir.
To perform these heavy-duty requirements, a high-pressure power steering hose must be able to handle fluid at peak temperatures as high as 150 degrees Celsius and pulsed pressures from 0 to 115 bar at 30 to 40 cycles per minute for up to 500,000 cycles without leakage. These stringent auto-industry specifications also require that such hoses must remain leak-free following a 20 cycle cold start test run at -40 degree Celsius.
Important Facts You Need to Know About Power Steering Hose
A quality power steering makes flawless steering possible. If you want the same thing for your car, install only proven high quality power steering hose.
You can't drive without the steering wheel. This is a literal and obvious fact that everybody knows-not unless if he or she does not know what a steering wheel is, of course. But that is okay because what is not commonly known is how the steering wheel really works. If you steer to the right, your car turns to the right and it turns to the left when you steer to that direction.
Some of you have knowledge about the steering wheel limited to that extent. We could practically name a new guessing game show by just asking random people on the street how the steering wheel works. But we do not really need to do that, of course. The answer readily lays on only one power steering component, that is, the power steering hose.
The power steering hose is part of the hydraulic powered steering system that takes the direction directly from you, and relays it to the steering rack. The steering rack does the job of making your vehicle turn to whichever direction you wish to go to. Power steering hoses use pressure from the steering fluid to power the steering rack, especially when you are turning into a direction. Power steering hoses, however, are prone to leakage over time. Although it depends on how they are installed, the quality of the power steering hoses also matters. The higher the quality of the power steering pressure hose is, the greater the delay of its deterioration.
Important Facts You Need to Know About Power Steering Hose
Hydraulic automotive technology brings a lot of benefits to the modern driver. Take power steering, for example. Power steering helps you turn your vehicle with less effort, making driving easier. For you to keep enjoying this , though, all components of the power steering system should be in top shape. This is particularly true for the power steering (P/S) hose. The P/S hose allows hydraulic steering fluid to flow to and from the steering rack. Your vehicle's power steering system contains a pressure hose and a return hose. The pressure hose takes fluid from the reservoir and feeds it to the steering rack. As soon as steering effort is reduced, fluid returns to the reservoir via the return line. With all the P/S hose's contact with high-pressure fluid, it really isn't surprising that this power steering component wears out easily. And you don't have to sweat it if that happens. Just browse through CarParts.com's catalogs, and we guarantee that you can find a high-quality, affordable replacement for your vehicle's stock P/S hose.
• Made from synthetic rubber, for resistance to wear and tear
• Equipped with sturdy clamps
• Can withstand high pressure and temperature
Choosing the Right Power Steering Hose
Nowadays, cars may have two or three power steering components. These components help drivers by adding energy to the steering mechanism, therefore reducing drivers' steering efforts regardless of the driving conditions they are in. One such component that makes up the power steering system is the power steering hose. Though oftentimes overlooked, power steering hoses play an important role in the power steering system by carrying the power steering fluid from the pump to other steering components.
Power steering hoses, just like other car parts, don't last because they are subject to extreme heat from the engine and other environmental factors. If your car's steering hoses are leaking, you need to replace them pronto. Looking for the right replacement hoses is as easy as 1-2-3, but choosing the right one for your car is very troublesome. If you're in the market for replacement hoses, there are some things that you should consider.
Price vs. Quality
As much as possible, you want to save money when repairing your car. But one thing that you should learn is that price influences quality. The price of power steering hoses range from $20 to $400, and there are many brands to choose from. When looking for the right power steering hoses, always buy from the manufacturers that you trust without sacrificing your budget.
Fabricated vs. Brand-new
If you're looking for new power steering hoses, then you probably heard about fabricated hoses. These hoses are fabricated or customized based on your preference. Some fabricated hoses are designed by hydraulic hose makers to withstand high pressure, so they last long. On the other hand, it's cheaper and easier if you'll just buy brand-new hoses from car part stores. We recommend that you choose car parts that best suit your driving style, and buy from makers or dealers that you trust.
High pressure vs. Low pressure
Power steering hoses come in pairs-high pressure and low pressure. One hose directs power steering fluid from the power steering pump to the steering mechanism. The other hose directs fluid back to the pump. These two hoses work together to give the steering mechanism the right amount of pressure to turn the vehicle. If there's a leak, it's important to check which hose is leaking. Hoses are usually sold individually, so to avoid buying the wrong hose, don't forget to check which hose is causing the leak.
DIY: Replacing Power Steering Hoses
Power steering hoses are very important. Once they start to leak, they have to be replaced to avoid steering difficulties. This DIY guide will teach you how you can easily replace your car's leaking hoses.
Difficulty level: Moderate
- Flathead Screwdriver
- Hose Clamp
- Power Steering Fluid
Step 1: Pop your car's hood. Then, place the container underneath the power steering pump to catch the power steering fluid.
Step 2: Find the two hoses attached to the power steering pump.
Step 3: Unscrew the hose clamp at the back of the pump to release the lower hose by turning the clamp's screw counterclockwise with your flathead screwdriver. Then, pull the hose away from the pump. Don't forget to drain the fluid into the container.
Step 4: Loosen the nut that attaches the upper hose to the pump by turning the wrench counterclockwise. Just like the lower hose, drain the power steering fluid into the container.
Step 5: Remove the hoses from the control valve by using your wrench to turn the nut at the end of each hose.
Step 5: With your wrench, attach the new hoses to the control valve and into the engine bay.
Step 6: Connect the upper hose to the back of the pump by sliding its nut over the valve and turning it in a clockwise direction.
Step 7: To connect the lower hose, slide the hose clamp up to where the hose meets the pump. Then, turn the screw in a clockwise direction using your flathead screwdriver.
Step 8: Fill the pump with power steering fluid up to the recommended fluid mark. Afterwards, start the engine.
Step 9: Turn the steering wheel several times. If the fluid stays between the "Add" and "Full" marks, the new hoses are working perfectly. If not, repeat the steps, and add more fluid if necessary.
