Guide to Service Power Steering: Maintenance and Repair

Service power steering refers to the maintenance and repair procedures performed on a vehicle’s power steering system. This crucial service ensures the power steering system functions properly, providing smooth and easy steering control for the driver.

Regular servicing of the power steering system includes checking fluid levels, replacing fluid if necessary, inspecting belts and hoses, examining the power steering pump and rack for leaks or malfunctions, and bleeding the system to remove air.

By addressing potential issues and maintaining the system’s components, service power steering helps ensure the overall performance and safety of the vehicle.

Taking care of the power steering system through timely maintenance and promptly resolving any problems is essential to avoid difficulties in steering, unusual noises, or a complete loss of power steering functionality.

What is Service Power Steering?

Service power steering involves inspecting, diagnosing, and repairing a vehicle’s power steering system. This includes checking the fluid level, refilling if needed, examining belts and hoses, testing the power steering pump and rack for leaks or issues, and bleeding the system to remove air.

These maintenance tasks ensure the proper functioning of the power steering and keep the vehicle’s steering system in good condition.

These services maintain the power steering system for smooth steering control. Power steering maintenance improves vehicle performance and safety.

Common Causes of Power Steering Problems

Common causes of power steering problems include low fluid levels, contaminated fluid, a broken power steering belt, a faulty power steering pump, and a lack of care and maintenance.

These issues can result in difficulty in steering, unusual noises, or a complete loss of power steering functionality. Regular maintenance and prompt resolution of any problems are crucial to ensure the proper functioning of the power steering system.

1: Low Fluid

When the fluid level in a vehicle with a hydraulic power steering system falls below a specified threshold, a warning light will often illuminate the instrument panel. The liquid has gradually evaporated, or there may be a leak.

The function of the system is impacted when there is insufficient fluid. Be careful to fill the container sparingly since doing so might cause the seal and the valve to break. Repairing any leaks as soon as possible can help avoid additional loss of liquids.

2: Contaminated Fluid

Power steering fluid tainted with contaminants may hasten the degradation of components and may even block fluid passageways. Impurities cause friction between fittings, leading to components’ progressive wear and tear.

Particularly impacted is the pump that controls the power steering. Contaminated fluid must be replaced with clean fluid as soon as possible. Always check the owner’s manual of your car for specific instructions, but it’s a good idea to check with the manufacturer first.

3: Broken Power Steering Belt

The crankshaft drives the power steering belt in pump-based hydraulic systems, usually located at the engine’s front. It operates independently of the alternator and water pump belts.

Over time, normal use can cause stretching, fraying, corrosion, or breakage. A damaged or worn-out belt leads to immediate power steering failure, accompanied by the “Service Power Steering” warning light. Replace the belt if necessary.

4: Bad Power Steering Pump

The power steering pump pressurizes the hydraulic system, making it simpler to steer and easier to turn the wheels. Although most pumps have a long lifespan, they may eventually develop leaks, break, or become noisy.

Performance deterioration reduces the steering assistance provided. Extreme driving conditions are a primary cause of pump failure. Replace a malfunctioning pump in your vehicle promptly.

5: Lack of Care and Maintenance

Poor road conditions can shorten the lifespan of steering components, subjecting them to wear or damage from potholes, harsh jolts, and sudden bumps. Exercise caution, especially on challenging terrains.

Power steering pumps have limited stress tolerance. Consider using a vehicle designed for extreme weather conditions or installing components capable of handling high temperatures and pressures before embarking on such journeys.

How do I handle the Service Power Steering light?

To address the power steering assist issue, safely pull over and switch off the car’s engine. Attempt restarting the engine to see if the indicator light goes away, as this may sometimes reset the system.

If the warning light persists, exit the vehicle and open the hood. Locate the power steering fluid reservoir, typically marked with a power steering wheel symbol on the cap.

For more clarification about its location, consult online resources or refer to the vehicle handbook for guidance.

  • Since you don’t have power steering fluid, find a local auto parts store.
  • Pipe leaks may lower fluid levels. Check the high- and low-pressure hoses for air leaks.
  • EPS vehicles don’t require hose or fluid checks. A control module executes steering angle sensor instructions.
  • This lets the module support driving. The alternator, electrical connections, and batteries might fail, causing system failure.
  • Frequently turning the ignition off and on fixes the problem. A system diagnostic is needed to find its cause if the issue is severe.

What is the Average Price for Power Steering Maintenance?

The average price for power steering maintenance can range from $200 to $350, depending on the specific problem. If a power steering pump replacement is required, the cost can be between $400 and $800.

Prices may vary depending on the vehicle’s make and model. In some cases, power steering issues can be resolved through cost-effective repairs, especially if the problem is related to blocked valves. Learning affordable and efficient methods to address a power steering service light is helpful.

Power Steering Maintenance Cost Price Range
Power Steering Repairs $200 – $350
Power Steering Pump Replacement $400 – $800

Auto Power Steering Repair Instructions

The power steering system may bind if the rack becomes clogged with debris. Sea foam Trans Tune cleanser is a good choice for cleaning it.

Step 1: To drain the power steering fluid, pop the hood and unscrew the cap.

Step 2: Remove some liquid using a turkey baster and store it in a separate container.

Step 3: Close the reservoir after placing 8 ounces of Sea foam cleaning inside.

Step 4: Give it 15 minutes of idling time. After every three to four minutes, you should rotate the wheel.

Step 5: Drive the vehicle around to ensure the power steering is functioning.

Step 6: Use the turkey baster to drain the whole reservoir.

Step 7: New power steering fluid must be installed.


Service power steering is crucial to maintaining a vehicle’s power steering system. By performing regular maintenance and addressing any issues promptly, drivers can ensure smooth and effortless steering control.

Timely checks of fluid levels, belts, hoses, and components help prevent potential problems and ensure the proper functioning of the power steering system.

Neglecting the service power steering can lead to difficulties in steering, loss of power steering assistance, and potential safety hazards. To preserve vehicle performance and safety, owners must prioritize servicing power steering.
