Is there fluid in an electric power steering rack?
As the owner of Kevin's Autos, I often encounter questions about the intricacies of vehicle systems, particularly when it comes to steering mechanisms. One common inquiry is whether electric power steering (EPS) racks contain fluid, similar to traditional hydraulic systems. In this article, we will explore the workings of electric power steering and clarify the role of fluid in these systems.
Understanding Electric Power Steering
Electric power steering is a modern advancement in automotive technology that replaces the traditional hydraulic steering systems. Instead of relying on hydraulic fluid to assist with steering, EPS uses an electric motor to provide the necessary assistance. This system is not only more efficient but also lighter and requires less maintenance.
Fluid in Electric Power Steering Racks
To answer the question directly: no, electric power steering racks do not contain fluid. Unlike hydraulic systems, which use fluid to transmit power from the steering wheel to the wheels, EPS systems utilize electric motors and sensors to achieve the same effect. Here are some key points to consider:
- Mechanism: EPS systems use an electric motor that is connected to the steering column or the rack itself. This motor provides assistance based on the driver's input and vehicle speed.
- Advantages: The absence of fluid means there are fewer components that can fail, leading to lower maintenance costs and reduced weight, which can improve fuel efficiency.
- Feedback: Electric power steering systems can also provide better feedback to the driver, as they can be tuned to offer varying levels of assistance based on driving conditions.
Conclusion
In summary, electric power steering racks operate without fluid, relying instead on electric motors to assist with steering. This innovation not only simplifies the steering system but also enhances the overall driving experience.

Frequently Asked Questions
Do I need power steering fluid if I have electric power steering?
You have electric power steering. No need for power steering fluid.
Does electric power steering fluid need to be changed?
So, do you need to change your car's power steering fluid? The short answer is yes! Every once in a while, you need to purge your power steering pump and clean it out. If you take your car for long drives, you might have to do this more often than people who use their vehicle for short car rides within the city.
Can an electric rack and pinion leak?
There are three main factors that can cause leaks: The hoses and lines are made from a flexible rubber that can crack; The connections can loosen; The seals between the steering column and the rack and pinion or around the tie rod connections can shrink, crack, dry out or become unseated.
Why is my electric power steering hard to turn?
Why does my steering wheel become hard to turn sometimes? It can be due to factors like low power steering fluid, a faulty power steering pump, worn or misaligned belts, or issues within the steering system.
Can electric power steering leak fluid?
It's also common for the supply and pressure hoses to develop holes as they age. If any of these components begin to fail, a leak can begin to develop, and you may see that telltale fluid on your driveway or garage floor. It could also be your power steering pump leaking.
How to add power steering fluid to an electric power steering?
If the fluid is below the “MIN” line, remove the cap (or leave the dipstick out) and add power steering fluid in small amounts, checking the level after each time. Don't fill it above the “MAX” line. Replace the cap or dipstick, and make sure it's sealed tight.
Do electric steering racks have fluid in them?
To keep this system running, your vehicle requires power steering fluid. This fluid should be replaced about every two years.
Can you change electric power steering fluid?
To change your power steering fluid, use a turkey baster, a fluid transfer pump, or a fluid change syringe to extract the existing power steering fluid from the reservoir. Then, add the new power steering fluid as recommended by your owner's manual.
Do you need oil for electric power steering?
No, electric power steering (EPS) systems do not require any type of fluid.
What kind of fluid do you use for electric power steering?
Some possibilities are synthetic, nonsynthetic, [and] automatic transmission fluid, or ATF. The most universal [common] power steering fluid is ATF.” Your power steering fluid type matters, but it isn't difficult to find.
