Have you ever had the misfortune of accidentally overfilling your power steering fluid? This article will discuss the consequences of overfilled power steering fluid and how to fix this. 

If your steering wheel is becoming difficult to turn or your car wheels are not responding smoothly to power steering, you should consider replacing your power steering fluid. Power steering fluid is a hydraulic coupling and lubricates the steering and front wheels. Let’s look at how to fill the power steering fluid properly. 

Overfilling Power Steering Fluid, is it wrong? 

Although you may not notice any problems with power steering after overfilling the reservoir, this does not mean that overfilling will not affect other engine components. If you don’t have a power steering fluid handy, purchase the correct one and not mix it with something wrong.

It takes about 4-5 minutes for the fluid to activate and start working. As you drive your vehicle for a while, the power steering fluid inside the engine may expand due to engine heat. This can result in the power steering fluid leaking all over the engine, negatively impacting engine performance and life. 

Consequences of an Overfilled Power Steering Fluid 

  • Leaking power steering fluid can cause the foam around engine components, causing wear and tear. 
  • If leaked power steering fluid is heated to 400 degrees Fahrenheit, it might spark a fire in the engine. 
  • If the fluid reaches the spark plug, it might cause it to fail, resulting in frequent engine misfires. 
  • It can make engine belts slippery, causing them to wear out. 

How Do You Avoid Overfilling Power Steering Fluids? 

– You can replace your power steering fluid reservoir with a bigger one to hold extra fluid. Purchase aluminum-body power steering reservoirs because they are more durable and can avoid fluid leakage. 

– Use a small funnel to pour the fluid since the reservoir has a very small entrance, which will avoid the fluid spilling on other engine components and slow down any excess fluid poured. 

How Do You Fix Overfilled Power Steering Fluids? 

  • Clean any excess oil that has been spilled on engine components or the power steering reservoir top. 
  • Remove any excess fluid using a turkey baster or syringe.

Further in this, we will also look at some of the methods to remove extra fluid. 

How To Drain Excess Power Steering Fluid? 

Method 1: Using syringes

Using syringes takes time and effort, but it is regarded as one of the most cost-effective ways to drain extra oil. Make sure to use at least 150 mL of the syringe. 


  1. First, remove the power steering reservoir’s lid. 
  2. Insert the syringe tip into the reservoir. 
  3. Suck the oil with the syringe by pulling its handle backward. 
  4. Repeat the procedure until the oil level is lower than the MAX point. 

Method 2: Using Fluid Evacuator 

Using a fluid evacuator to remove excess oil is one of the most successful and simplest of all methods. This approach requires you to buy a fuel evacuator, which might be pricey. 


  1. First, remove the power steering fluid reservoir’s lid. 
  2. Insert the fluid evacuator hose into the reservoir. 
  3. Turn it on. It will create air pressure to suck the extra fluid and store it in a container. 
  4. Switch off when the oil level reaches between MIN and MAX. 

Method 3 – Removing the Hose 

This method requires no additional instruments other than a plier clamp. However, pulling the hose can cause fluid to spill, so use a towel and gloves before removing the hose. 


  1. Take the clamp off the low-pressure line. 
  2. Remove the hose and cover it with a cloth since fluid may spill. 
  3. Place the funnel beneath the metal and rubber return lines to pour the excess oil directly into the container. 
  4. Allow the fluid to drain until your fluid level returns to normal. 

How to Refill Power Steering Fluid Properly?

  1. Ensure you purchase a power steering fluid designed for your vehicle; now, check the fluid level using the marks on the power steering reservoir. You can also use a Dipstick to measure the oil level. 
  2. If the level is below the MIN mark, your power steering fluid level is low. 
  3. Remove the reservoir top and insert a funnel inside. 
  4. Fill the power steering fluid reservoir through the funnel. Anything extra above the MAX point of the reservoir is considered overfilled fluid.

FAQ’s on Overfilling Power Steering Fluid

Your vehicle's usage and the condition usually determine this. A power steering fluid change is usually required every 40,000-80,000 miles. If your engine is experiencing any symptoms below, you may need to replace your power steering fluid.

  • If your engine makes a whining sound.
  • Your steering wheel is hard to turn.
  • The fluid in the reservoir appears dark brown or black.

No, having foam in your power steering fluid is not normal. The foam in the fluid means pollutants and air within the fluid.

Foam can occur due to a poor internal-external hose or improper piping. Low fluid in the reservoir can lead to a power steering pump pumping partly fluid and partly air, creating foam inside the liquid.

Too much fluid in the reservoir can move to the low or high-pressure pipelines, causing air bubbles or foam to form inside the pipelines. This can make the steering wheel more hard and difficult to turn.


Overfilling power steering fluid is bad for your engine’s overall performance. It can cause wear and tear in many engine components. 

So, when refueling your power steering fluid, use a funnel. You should also clear up any extra oil that has spilled on other engine components. If the fluid in the reservoir exceeds the MAX level, drain it as quickly as possible.
