There are some things in a vehicle that people don’t pay much attention to until there’s something wrong with them. One day, the wheel seems smooth and responsive, while the other day it was hard, noisy, or erratic when you attempt to maneuver around in a parking lot. There could be multiple reasons behind that, but most of the time, a power steering issue is caused by poor quality or quantity of power steering fluid.
Our pros here at Maclane’s Automotive help our clients avoid the problems related to their steering system becoming inoperable due to fluid-related concerns. We’ll ensure you won’t face a situation where a minor fluid problem would result in a failed pump, damaged components, and a loss of assist at a critical moment.
What Power Steering Fluid Does
Power steering fluid is a hydraulic fluid responsible for transmitting energy from the wheel to the steering assembly and assisting the steering process. An adequately working steering system enables you to perform smooth turns at a low speed and provides you with stable control over the vehicle.
A conventional hydraulic power steering system features a pump that supplies the fluid to the hoses connected to the steering mechanism. Along with its main function, the fluid is responsible for lubricating the components inside the system and reducing the temperature level. With time, the fluid tends to break down because of heat cycles and wear. Minor leaks may also cause its depletion.
Electric power steering (EPS) used in some modern cars doesn’t employ power steering fluid at all. It can be difficult to understand whether you have EPS or hydraulic power steering in your vehicle. We can tell you in no time, or you might refer to your owner’s manual.
Signs Your Power Steering Fluid Needs Attention
There are certain signs that power steering fluid is running low or requires replacement. The following ones are the most common:
- A whining, groaning, or squealing noise when turning the wheel (especially at low speed)
- Steering that feels stiff, jerky, or harder than usual, especially when parking or making tight turns
- Visible fluid under the vehicle, often near the front end (power steering fluid can look amber, red, or brown depending on type and condition)
- A power steering warning light on the dashboard (varies by vehicle)
If the wheel suddenly becomes very hard to turn, treat it as urgent. It may still steer, but it takes much more effort, and that can be dangerous in traffic or during quick maneuvers.
When To Check Power Steering Fluid
For many vehicles with hydraulic power steering, checking the fluid, is a quick maintenance habit that can prevent expensive repairs. We generally recommend:
Check it once a month if your vehicle is older, has high mileage, or has had prior leaks.
Check it at every oil change if everything has been stable and there are no symptoms.
Check it right away if you hear whining while turning, notice steering changes, or see fluid spots.
Also, it is smart to check the level before a long road trip or towing, since extra load and heat can stress the system.
How To Check Power Steering Fluid (The Safe Way)
In case your vehicle has a power steering reservoir, the lid may include a dipstick, or there will be “MIN/MAX” markings on the reservoir itself. There are certain types of vehicles for which the test needs to be conducted both when the engine is cold and when it is hot. It might be best then to check the underhood label or owner’s manual.
Below is a sample of a generic method that will help establish whether you need to fill your vehicle with power steering fluid:
Make sure your vehicle is parked on flat ground and turned off. Locate the power steering fluid reservoir, wipe clean the area around the cap to keep dirt out of it, and take off the cap. Take a look at the level of the fluid marked on the reservoir and the condition of the fluid.
It must be healthy and have no signs of being dark, bubbly, or foamy, since this would mean that there is a problem. Should any of these signs appear, however, simply filling the fluid might not be enough, as it is indicative of problems such as leaks in the system or a defective hose that needs replacement.
One more thing to consider is fluid type. While there are vehicles requiring power steering fluid specifically, others may need a certain type of ATF fluid. Using the wrong kind may lead to swelling of seals, noises, and other issues.
Top-Off Vs. Flush: What Your Steering System Actually Needs
If you have a low fluid level but not a dirty one and your vehicle makes no unusual noise or leaks, filling the power steering fluid could be helpful. Otherwise, though, filling the fluid is not going to solve the issue. Unlike engine oil, power steering fluid does not burn but can leak and reduce fluid levels.
Therefore, when it is contaminated, noisy, or the fluid replacement is due, flushing is a better solution. New fluid will lubricate components, making noises disappear.
At Maclane’s Automotive, when performing a fluid change, we always check for leaks because most of the time, the main causes of the problem are the following:
- Leaking return or pressure hoses
- Seeping reservoir seals
- Leaks at the steering rack or pump
Catching a small seep early often saves the pump and keeps your steering consistent.
What Happens If You Ignore Low Power Steering Fluid?
Low or dirty fluid levels may lead to overheating of the pump and premature wear within the rack or steering gear. As the pump fails, you might notice increased whining noises, poor assist function, or times when the effort needed for steering becomes greater. Pump replacement, hose replacement, or rack repair will likely cost significantly more than taking care of a leak early on.
