What is a steering pump?

The power steering pump is driven by the engine's crankshaft via a belt-pulley mechanism. The pump is usually located in the front of the engine, adjacent to the alternator or AC compressor. The steering pump compresses the hydraulic fluid at a rate directly proportional to the speed of the engine. The pump is built as such to provide the required pressure in different engine conditions such as idling or running at high speeds.
All steering pumps are equipped with a rotor; the designs of the rotor's fins are what determines their type. Based on the design of the rotor's fins, the classification is as follows:

• Rotary Vane Steering Pump:

These are the most common kinds of pumps used in automobiles. The vanes are mounted on the rotor such that they touch the housing wall. The power steering fluid is caught between the vanes, the rotor and the housing wall.

• Roller Steering Pump:

Roller steering pumps, as the name signifies, have rollers that ride along the inner contour of the pump. The rotor has wide V-shaped grooves cut into its sides. The rollers are pushed to the outer edge of the pump's housing by means of centrifugal force. This action traps the power steering fluid and compresses it.

• Slipper Power Steering Pump:

These types of power steering pumps contain springs attached to the rotor. The springs have slippers fitted on their tops and the slippers are in continuous contact with the pump's wall. The pressure build-up inside the pump causes the fluid to be compressed.

What is the function of steering pump?

A power steering pump provides the required hydraulic pressure to steer your automobile with a minimal effort on the steering wheel. When the engine is running, the power steering pump's rotor, which is connected to the pulley, turns. The spinning rotor pressurizes the fluid and delivers it to the steering gearbox. The pulley has open grooves on its sides that mesh precisely with the rubber belt. A rotary valve, torsion bar and a spool valve assembly are other components involved in directing the steering fluid from the pump in the appropriate direction based on the rotation of the steering wheel.

What the symptoms of bad steering pump?

Power steering pumps will last for a while but they don't usually last for the lifespan of the vehicle itself. Eventually, the power steering pump in your vehicle is going to go bad and stop doing the job that it is supposed to do. There are plenty of symptoms that will occur when this starts to happen. Below are the top 5 symptoms to look out for when the power steering pump goes bad.

Difficulty Turning Wheel.

The most common symptom you will experience is when you have difficulty turning the steering When you go to make a turn, the steering wheel will feel very stiff and you'll have to use a lot of strength and force just to make a basic turn. This should prompt you to check the power steering pump because it could mean that it needs replacing.

Whining Noise.

When you try to turn your steering wheel, you might hear a whining noise. This is an indication that a problem exists inside of your power steering system. The whining noise could be due to many reasons, one of which being that the power steering pump has a leak in it. Either that or the power steering fluid might be too low. But you'll want to check on both just in case.

Squealing Noise.

A squealing noise might be heard when you first turn on your vehicle's engine. This noise will remain consistent for about a minute after the car is started. The reason for this likely has to do with a bad power steering pump that is making the belt inside the system slip. This means you must replace the pump and realign your belt.

Groaning Noise.

This is the worst noise of them all. If you have neglected to repair or replace your already dysfunctional power steering pump, it will eventually make groaning noises. This usually occurs if there is a leak or insufficient fluid going through the pump, which will ultimately ruin the whole power steering system. Not only will you have to replace the pump at this point, but you may have to replace the whole system as well.

Chrome Flakes in Fluid.

Checking the power steering fluid can tell you a lot about the condition of the power steering pump. Aside from assuring there is an adequate amount of power steering fluid in the system, you'll also want to check to see the color and condition of the fluid. If you see dark gray colors or chrome flakes in the fluid, then it means your pump is degraded.

How to install a steering pump in a car?

In many cases, the power steering pump will not function because the serpentine or drive belt is broken and needs to be replaced. It's also common for the power steering pulley to break or wear out. If you notice these symptoms and have inspected the power steering pump, replacing this component is the best course of action. This job is rather simple to complete, but you should always read the exact procedures your vehicle manufacturer recommends in the service manual.

Materials Needed:

• Hydraulic line wrenches
• Pulley removal tool
• Boxed end wrench or ratchet wrench
• Drain pan
• Replacement power steering drive or serpentine belt
• Replacement power steering pulley
• Replacement power steering pump
• Safety equipment (safety glasses & plastic or rubber gloves)
• Shop rags
• Threadlocker
According to most experts, this job should take about two or three hours to complete. Make sure you give yourself enough time to work on this project and try to complete it all on the same day to avoid missing steps.
Before you start on this job, make sure you have a good supply of shop rags placed under all hydraulic lines that you might remove. Hydraulic fluid is very difficult to remove from metallic components and the hoses will leak when you remove them.

Step 1: Disconnect the vehicle's battery.

Before removing any parts, locate the vehicle's battery and disconnect the positive and negative battery cables.
This step should always be the first thing you do when you work on any vehicle.

Step 2: Lift the vehicle.

Do this with a hydraulic lift or jacks and jack stands.

Step 3: Remove the engine cover and ancillary parts.

This will give you clear access to the power steering pump.
Most vehicles have easy access to the power steering pressure switch while others require you to remove a few components including: engine cover, radiator fan shroud & radiator fan, air intake assembly, alternator, AC compressor, and harmonic balancer.
Always refer to the vehicle's service manual for exact instructions on what you need to remove.

Step 4: Remove the serpentine belt or drive belt.

To remove the serpentine belt, loosen the tensioner pulley that is located on the left side of the motor (as you're looking at the motor).
Once the tensioner pulley is loose, you can slip the belt off rather easily. If your power steering pump is driven by the drive belt you'll have to remove this belt as well.

Step 5: Remove lower engine covers.

On most domestic and foreign cars, there are one or two engine covers underneath the engine.
This is commonly known as a skid plate. To gain access to the power steering pump lines, you'll have to remove these.

Step 6: Remove the radiator fan shroud and the fan.

This gives easier access to the power steering pump, pulley and supporting lines that need to be removed.

Step 7: Disconnect lines going into power steering pump.

Using a socket and ratchet or a line wrench, remove the hydraulic lines that are connected to the bottom of the power steering pump.
This is usually the supply line that is connected to the gear box. Make sure you place a drip pan under the vehicle before attempting this step as power steering fluid will drain.

Step 8: Let power steering fluid drain.

Let it drain from the pump for a few minutes.

Step 9: Remove the mounting bolt underneath the power steering pump.

There is usually a mounting bolt that connects the power steering bolt to either a bracket or the engine block. Remove this bolt using a socket or end wrench. • Note: Your vehicle may not have mounting bolts located underneath the power steering pump. Always refer to your service manual to determine if this step is needed for your specific application.

Step 10: Remove the additional hydraulic lines from the power steering pump.

Once you've removed the primary supply line, remove the other attached lines.
This includes the supply line from the power steering reservoir and the return line from the gear box. Some vehicles have an electrical harness attached to the power steering pump. If your vehicle has this option, remove the harness at this point of the removal project.

Step 11: Remove the power steering pump pulley.

In order to successfully remove the power steering pump pulley, you'll need to use the right tool.
This is often referred to as a pulley removal unit. The process for removing the pulley is noted below, but you should always read the manufacturer's service manual for their recommend steps.
This involves attach pulley removal tool to the pulley and guide the locking nut onto the edge of the pulley. Using a socket and ratchet, slowly loosen the pulley while holding the pulley attachment nut with a corresponding end wrench.
This process is very slow, but necessary in order to correctly remove the power steering pulley. Continue loosening up the pulley until the pulley has been removed from the power steering pump.

Step 12: Remove mounting bolts.

Using an impact wrench or regular socket and ratchet, remove the bolts holding the power steering pump onto the bracket or the engine block.
Usually there are two or three bolts that need to be removed. Once this has been completed, remove the old pump and take it to a workbench for the next step.

Step 13: Transfer the mounting bracket from the old pump to the new pump.

Most replacement power steering pumps do not come with a mounting bracket for your specific vehicle.
This means you'll have to remove the old bracket from the older pump and install it onto the new bracket. Simply remove the bolts that secure the bracket to the pump and install on the new pump. Make sure to install these bolts using threadlocker.

Step 14: Install the new power steering pump, pulley and belt.

Anytime you install a new power steering pump, you need to install a new pulley and belt.
The process for installing this unit is exactly opposite from the removal and is noted below for your review. As always, refer to your vehicle service manual for specific steps as they will vary for each manufacturer.

Step 15: Secure pump to engine block.

Secure the pump to the engine block by screwing bolts through the bracket to the block.

Step 16: Install new pulley using the pulley installation tool.

Attach all hydraulic lines to the new power steering pump (including bottom supply line).

Step 17: Reinstall remaining parts.

Reinstall all parts removed to give better access.
Reinstall new serpentine belt and drive belt (refer to manufacturer's service manual for proper installation procedures).
Reinstall radiator fan and shroud, lower engine covers (skid plates), and any parts you had to remove initially in the exact opposite order you removed them.

Step 18: Fill power steering fluid reservoir. Step 19: Clean up underneath vehicle. Step 19: Clean up underneath vehicle

Before you finish the job,make sure to remove all tools,debris,and hardware from under the vehicle to avoid running over them with your vehicle.

Step 20: Reconnect battery cables. Test driving the vehicle Test driving the vehicle

After you've reinstalled all components that have been removed and you've filled the power steering fluid to the “full” line, you need to prime the power steering system. This is best completed by starting the engine while the front wheels are in the air.

Step 1: Prime the power steering system.

Start the vehicle and turn the steering wheel to the left and right a few times.
Shut off the motor and refill the power steering fluid reservoir. Complete this process until the power steering fluid reservoir does not require refilling.

Step 2: Perform a road test.

A good road test of 10 to 15 miles is recommended when you've replaced the power steering pump.
Start the vehicle first and inspect underneath the vehicle for any leaks before you take the vehicle on any road test.
