Does Electric Power Steering Have Power Steering Fluid?
2 Answers
Electric power steering does not use power steering fluid. The characteristics of electric power steering are: 1. It can significantly improve the dynamic and static performance of the vehicle; 2. It reduces fuel consumption; 3. It enhances steering responsiveness; 4. It improves handling stability; 5. It enhances the steering return characteristics; 6. It reduces environmental pollution; 7. The system has a simple structure and occupies less space. Electric power steering uses an electric motor to directly provide assistance, with the assistance level controlled by the electronic control unit (ECU). Power steering fluid is a special liquid used in the vehicle's power steering pump, which, through hydraulic action, makes the steering wheel lighter to operate, similar to automatic transmission fluid, brake fluid, and shock absorber fluid.
Electric power steering systems typically don't use power steering fluid because they rely on an electric motor to assist with steering instead of a traditional hydraulic system. I remember chatting with a mechanic at the auto shop before, and he told me the advantage of electric power steering is that it's hassle-free—no need for regular checks or fluid changes, which avoids risks like leaks or pump failures. Many new cars now come equipped with this system, including mine. Although there's no power steering fluid to worry about, it's still important to ensure the wiring connections on the steering column are intact and occasionally check the electronic control module during maintenance to prevent rust or looseness. This makes steering smoother and driving more effortless, especially since there's one less component prone to issues. Overall, electric power steering is much simpler to maintain.
