Knowing the symptoms of a bad power steering pump is helpful and can save you from unprecedented accidents. For cars with power steering to function, power steering pumps are necessary. The cost of the job might range from $100 to $200 for a new power steering pump if you do it yourself to $500 if you hire a mechanic. However, it is still much less expensive than buying a new car. Circulating power steering fluid to your steering wheel is the responsibility of your power steering pump. This makes turning the steering wheel while you’re driving a lot simpler. You’re going to work out a lot if you keep driving with a poor power steering pump, though!

Knowing when your pump is having issues might help you avoid expensive repairs and hazardous driving conditions. Thus, in this article, we’ll be discussing the following;


So, let’s dive in!


What is a power steering pump?

The power steering pump is in charge of supplying the system with the hydraulic pressure required for proper operation. It controls the power steering fluid, which contributes to the steering being lighter and simpler to use. It is linked to your engine via a belt-pulley system that is powered by the crankshaft.

The rotary vane, roller, and slipper are three different types of power steering pumps. All three work on the same premise, which is to pump the fluid to the entire system, despite the fact that each one has distinct designs and workings. A typical car weighs around 2,900 pounds. Of course, that will change based on the kind of vehicle you’re operating.

A huge pickup truck can weigh twice as much as a midsize vehicle, which can weigh up to 3,400 pounds on average. Cars, in a nutshell, are heavy. However, power steering allows you to navigate even at slow speeds with ease. Hydraulic, electro-hydraulic, and totally electric power steering systems are the three different types available. In contrast to mechanical systems, which only rely on a motor to move the fluid under pressure, hydraulic systems use a pump. The first two employ an incompressible fluid that, when compressed, transforms mechanical force into fluid power.

Where is the power steering pump located?

The power steering pump is typically located in front of the engine or on the passenger side of the car. You may locate it by following the serpentine belt, which runs through it.

The placement of the steering pump will also depend on the drivetrain type you have. With front-wheel drive cars versus those with rear-wheel drive, it’s typically in different places.

The electrical steering pump is frequently found close to the base of the steering column, closer to the steering column itself. Refer to the details in your repair handbook if you can’t find where your steering pump is.

What are the functions of A Power Steering Pump?

The hydraulic fluid is pressurized by the power steering pump. This pressure allows the driver to easily turn the steering wheel. A system of pulleys and belts powers the pump. Rotating vanes inside the pump are drawing hydraulic fluid from the return line. The high pressure causes fluid to be driven into the outflow at that point.

The amount of pressure generated is a function of the engine’s rotational speed. The more fluid is blasted out the faster it is moving. The pressure relief valve is also there to allow the extra fluid to return to the pump.

Power steering is often provided by a hydraulic and mechanical system in vehicles. Even when the wheels are not moving, the pumps do reduce the vehicle’s efficiency and power. For this reason, some producers opt to employ an electric pump in combination with an electric power assist. These mechanisms are also susceptible to breakdown.

What causes a faulty power steering pump?

These are the following  causes of a faulty power steering pump;

How do you Test a power steering pump?

It is better to look through the complete system before checking the power steering pump. If you possess certain fundamental tools and knowledge, you do not need to be a mechanic.

Beyond this, a power steering pressure test would be required. The majority of home mechanics won’t feel comfortable with this, though. You might feel more comfortable at this point having a qualified mechanic examine the car.

Ways to avoid power steering problems

Power steering systems that are kept up to date can last for many years with little maintenance. Check to see if the engine is supplying enough power and that the belts and pulleys are not creaking. To prevent belts from snapping while being worn, replace any that are frayed or torn. Make sure the power steering fluid is at the proper level and fill it off as needed. Watch out for any leaks of hydraulic fluid or strange-colored liquid. There should be no moaning sounds coming from the power steering pump as it operates. By doing this, the functionality of the bearings and other parts is ensured.

While idling and turning the steering wheel, the engine rpm should remain constant. Unreliable sensors or a failed power steering pump are indicated by rough idling while steering. Check the pipes and hoses in the steering system for signs of wear and tear.

How Much Does It Cost To Replace A Power Steering Pump?

A power steering pump replacement typically costs between $500 and $800. About half of the price may be made up of parts, with the remaining cost being made up of labor. You would only have to pay for the parts if you could change the power steering pump yourself.

Most automobile models require two to three hours to change a power steering pump, although this varies on the kind of vehicle you drive. If the power steering pump is positioned lower on the side of the motor in a front-wheel drive car, changing it may be more challenging.

What happens when the power steering pump goes bad?

This may be accompanied by a stiff wheel that occasionally makes turning it more difficult or that is slow to react when you start a turn. When you turn the key in the ignition, your car may even make a screaming noise if the power steering pump is malfunctioning.

What spoils the power steering pump?

These are some typical reasons for a failing power steering pump: hazardous steering fluid. low levels of power steering fluid. a drive belt (power steering belt) that is damaged or worn out.

How long will a failing power steering pump last?

Before a pump replacement is necessary, the power steering system on the majority of vehicles will last between 100,000 and 150,000 miles. Replacement costs for the power steering pump are typically avoidable. Just make sure you continuously monitor and uphold your fluid-scheduled maintenance routine.

Does a bad power steering pump sound?

A pump is present in every hydraulic power steering system to produce the pressure necessary for the fluid to function. The pump makes an audible noise while you drive when there is a problem with the system. Depending on your speed and how you try to drive your car, the sound has a wailing, buzzing quality.

How does a steering pump fail?

If your system doesn’t have enough fluid, your pump won’t be properly lubricated, the fluid temperature can increase, and your pump may prematurely wear out. When all of these factors are present, power steering will fail early and be difficult to repair.

Can the steering pump be repaired?

Depending on what caused the fault, yes. A damaged bearing or seal can be replaced independently. However, when it comes to an electro-hydraulic servo pump, the control unit is frequently the problem. However, even that may frequently be fixed without any issues.
