5. Add new fluid to the reservoir with the help of a funnel until the reservoir is full. 6. Turn the engine on. 7. Turn the wheel all the way a few times. When you do this, the old and black power steering fluid will discharge through the hose you just unplugged. 8. Refill the reservoir with new fluid as the fluid level decreases. 9. The small pulley is attached to the driveshaft of the electric motor. A belt wraps around both pulleys and acts as the first stage of a two-stage gear reduction that makes EPS possible in a light Step 7: Remove the electrical harness from the power steering control unit. There are usually two electrical harnesses that are attached to the steering control unit. Remove these harnesses and mark their locations with a piece of tape and a pen or a colored marker. Step 8: Remove the steering column from the vehicle. Some newer cars have started being manufactured with an electronic power steering system, or EPS. These are very different from their older cousins. There is no power steering pump. There is no need for power steering fluid. The entire system is electronic, and is controlled by a power steering control unit. It's a streamlined power steering system. There’s no power steering pump, no drive belt, no hoses, and no hydraulic fluid. That’s a lot of noisy, leaky parts that we can toss over our shoulder. The mechanics of EPAS are fairly simple. The power steering control module (PSCM) calculates how much assist is needed based on the driver’s input Electric power steering fluid is a type of oil that helps to move the steering wheel and controls the amount of torque applied to the wheels. There are several different types of electric power steering systems, but all use some form of fluid to help power the steering. .
