- Pressure and return hoses
- Steering gear or rack
Tighten any loose connections. If a hose is cracked, replace it. For leaks from the power steering pump, the entire unit may need rebuilding or replacing.
Damaged Power Steering Pump
Issues with the pump can cause loss of power assist. Symptoms include difficulty turning the wheel and loud noises when turning. If caught early, some pumps can be rebuilt. But if severely damaged, a new replacement pump is needed.
Dirty or Contaminated Fluid
Contaminants in the fluid can damage the power steering components. Signs include steering noise, loose feeling steering and leaking fluid. To fix, thoroughly flush the system and replace all power steering components. Then refill with clean, fresh power steering fluid.
Loose Steering Belt
The power steering pump is driven by the serpentine belt. If this belt is loose, the pump won't spin properly. This can cause difficulty steering. Tighten a loose belt or replace if worn. Consult your vehicle repair manual for proper belt tension specs.
Summary
Power steering issues can make your vehicle difficult and unsafe to drive. Pay attention for symptoms like steering noise, loose feeling steering and leaking fluid. Proper fluid level, flushing contaminants, replacing worn parts and tightening belts can get your power steering working properly again.

Symptoms of Low Power Steering Fluid
Power steering fluid is essential for proper functioning of the power steering system in your vehicle. When fluid levels run low, several noticeable symptoms can occur.
Difficult Steering
The most obvious sign of low power steering fluid is increased difficulty turning the steering wheel at low speeds. This occurs because low fluid levels reduce the hydraulic pressure that assists with steering.
Steering Wheel Noises
As fluid runs low, the power steering pump may whine or make groaning noises when turning the wheel. This is due to increased friction within the steering system.
Leaking Fluid
One cause of low fluid levels is a leak in the power steering system. Check around the pump, hoses and steering gear for signs of leaking fluid.
Steering Vibrations
If levels get critically low, air can get into the power steering lines. This causes steering wheel vibrations and reduced steering assist.
Slow Steering Response
You may notice sluggish or disconnected steering response as fluid levels fall. There will be a delayed reaction when turning the wheel.
Overheating
Low fluid can cause the power steering pump to overheat from increased friction. Signs include hot fluid, steaming or burning smells.
Dashboard Warning Light
Some vehicles have a power steering warning light on the dash. This will illuminate if fluid levels are dangerously low.
Don't ignore symptoms of low steering fluid. Top up levels immediately to avoid damage to the power steering system. Refer to your owner's manual for proper filling instructions.
Refilling and Changing Power Steering Fluid
Maintaining proper power steering fluid levels is essential to prevent damage to the power steering system. Here is how to properly refill fluid and complete a fluid change.
Checking the Fluid Level
Start by locating the power steering fluid reservoir, which is typically near the radiator. The reservoir has high and low level markings:
- Fluid should be at the "FULL/MAX" mark when cold
- When warmed up, the level may drop slightly to the "HOT/MIN" mark - this is normal
Adding Fluid
If low, add fluid to bring it up to the proper level. Use a funnel to prevent spills.
Important: Only use the specific type of fluid recommended in your owner's manual. Mixing fluids can damage the power steering system.
Flushing Old Fluid
For a complete fluid change, you'll need to drain and flush the entire system. This involves:
- Raising the front of the vehicle and supporting it on jack stands
- Locating the return hose from the power steering pump and disconnecting it
- Starting the engine and allowing fluid to drain into a container
- Reconnecting the return hose once fluid runs clear
- Adding new fluid to fill the reservoir
This process circulates fresh fluid throughout the whole power steering system to flush out contaminants.
Flushing Intervals
Refer to your owner's manual, but fluid flushes are typically needed every 30,000-50,000 miles or 2-3 years.
Properly maintaining your power steering fluid prevents damage and keeps your steering operating safely. Check levels monthly and change the fluid regularly.
Choosing the Right Power Steering Fluid for Your Vehicle
Using the correct type of power steering fluid is critical to protect your vehicle's steering system. The wrong fluid can damage seals and cause leaks.
Check Your Owner's Manual
The first step is consulting your owner's manual or a repair database for your specific make and model. Manuals provide the exact fluid specifications required by your vehicle.
Some common types include:
- DEXRON III - Used in many GM vehicles
- MERCON V - Required in newer Ford models
- CHF202 - For many Chrysler, Dodge, and Jeep vehicles
- PSF-IV - Recommended for Hondas
Fluid Labels
When purchasing fluid, check that the label states it meets the specification for your vehicle. Using a universal or generic fluid can cause leaks over time.
Color and Texture
Note the color and texture recommended. Power steering fluid can range from amber and translucent to red or purple in color. The texture varies from thin and watery to thick like motor oil.
Consider Age and Mileage
If your vehicle is over 75,000 miles, a synthetic or high mileage formulation may help condition seals and prevent leaks.
Avoid Mixing Fluids
Never mix different types of power steering fluid. This can cause gelling and clog components. Flushing the system is required to change fluid types.
Topping Off Existing Fluid
When topping off existing fluid, use the same fluid already in the system. Even if specs have changed for newer models, mixing fluids during top-offs can still create issues.
Summary
Choosing power steering fluid specifically formulated for your make and model keeps your steering system operating safely. Refer to manuals and labels to select the correct fluid. With the right fluid, your power steering can go the distance.
Extending the Life of Your Power Steering System
The power steering system is crucial for easy steering and control of your vehicle. With proper maintenance, you can maximize the life of your power steering components.
Regular Fluid Changes
Over time, heat and contaminants break down power steering fluid. Flushing out old fluid and refilling with fresh fluid helps lubricate and cool the system.
- Change fluid every 30,000 miles or 2 years minimum
- Use only the specific fluid type recommended for your vehicle
Check the Pump and Belt
Inspect the power steering pump pulley and belt periodically for signs of wear. A loose belt can reduce pressure and lead to pump damage over time.
