Parts for your 2015 Ford Fiesta-Power steering pump

Maintenance and Replacement of the 2015 Ford Fiesta's Power Steering System

The 2015 Ford Fiesta does not utilize a traditional power-steering pump. Instead, it features an electric power-assisted steering (EPAS) system. This is a shift from the hydraulic systems that require a power-steering pump, hoses, and hydraulic fluid. In an EPAS system, the assist is provided by an electric motor which is more efficient and requires less maintenance. However, similar due care and attention are needed to maintain optimal performance over the vehicle's lifespan.

Though the absence of a power-steering pump simplifies the maintenance, there are still several key aspects to consider regarding the upkeep of the electric power steering system in your Ford Fiesta:

1. Regular System Inspection: It's a good idea to inspect the steering components for any visible wear and tear. Look for signs of damage or corrosion on the steering gear and linkage.
2. Steering Rack and Column Check: Ensure that the steering column and rack remain securely fastened and properly aligned. Any deviance might result in poor alignment and uneven tire wear.
3. System Calibration: Over time, the EPAS system might require recalibration. This involves checking the sensors and ensuring that they provide accurate data to assist in steering efforts, especially after an alignment or repair.
4. Software Updates: As with any electrical system, ensuring that the onboard computer software is updated can prevent unforeseen issues and improve the system's functionality. Consult your local dealership for occasional firmware or software updates.
5. Steering Fluid Levels: While electrified, the system benefits from hydraulic steering fluid as a backup. However, due to its little usage in daily steering functions, check the fluid levels at every service but note that it's typically not consumed like in traditional hydraulic power steering systems.

When any abnormality becomes evident - such as unusual noises, resistance in steering, or error messages on the dashboard's display screen - immediate attention is required. Delaying a visit to the mechanic might exacerbate the issue, leading to more significant and costly repairs.

The EPAS system, while requiring less frequent mechanical maintenance, still benefits from regular servicing that checks electrics, software, and hardware. If your trusted mechanic finds components requiring attention, follow their professional advice. They'll provide insights into the EPAS system condition and the necessity of proactive measures to maintain an efficient and responsive steering experience.
