Understanding the Power Steering Pump on the 2018 Subaru Outback

The 2018 Subaru Outback is a popular choice among Aussie drivers, known for its reliability and rugged capability. When it comes to steering, many people wonder whether this model comes with a traditional power steering pump. The short answer is that the 2018 Subaru Outback does not use a conventional hydraulic power steering pump. Instead, it features an Electric Power Steering system, commonly referred to as EPS.

So why does the 2018 Subaru Outback skip the power steering pump? Traditional power steering pumps rely on a belt-driven hydraulic system powered by the engine. This pump circulates pressurised hydraulic fluid to assist with steering effort. While effective, this setup uses engine power and requires upkeep like fluid changes, hose checks, and pump replacement over time.

The Outback's EPS system uses an electric motor to assist the steering column, which means no hydraulic fluid, no belts, and no hydraulic pump to maintain. The advantage of this system is its efficiency. Since the electric setup only consumes power when steering assist is needed, it improves fuel economy and reduces maintenance costs. Additionally, EPS systems are more adaptable and can offer variable assist based on speed and driving conditions, enhancing the driver's experience.

With no hydraulic pump involved, the 2018 Subaru Outback's steering system is simpler in many ways. This means there is no power steering pump to replace or service. Instead, any concerns with steering assist would typically involve electrical components such as the assist motor itself, wiring, or sensors.

From a maintenance perspective, EPS systems like the one in the 2018 Outback generally require less attention. There is no need to check or change power steering fluid since it does not exist in this setup. You also avoid common issues related to hydraulic pumps such as leaks, noisy pumps, or sudden loss of assist due to pump failure. However, as with all vehicle systems, keeping an eye on the electronic components during regular servicing is important.

Despite not having a traditional power steering pump, the 2018 Subaru Outback offers excellent steering responsiveness and control. Drivers enjoy smooth and consistent steering assistance, making it a pleasure to handle both on city streets and rougher terrains. If any concerns arise about steering feel or assist, it's best to have the system checked by a qualified Subaru technician who can diagnose the EPS components.

In contrast, vehicles with hydraulic power steering pumps require more frequent inspections. For those owning older Subaru models or other cars with hydraulic power steering, you would commonly be advised to monitor fluid levels, inspect hoses and belts, and listen for unusual noises from the pump. Regular power steering fluid flushes are often recommended to maintain smooth operation and prevent wear.

For drivers unfamiliar with EPS, it might feel different at first, as the steering effort can vary depending on speed. At low speeds, such as parking or tight manoeuvres, full assist is available to reduce effort. At higher speeds, the system reduces assist to improve stability and feedback. This calibrated approach is something you do not get with traditional hydraulic systems which tend to provide consistent assist at all speeds.

Simply put, the lack of a power steering pump in the 2018 Subaru Outback reflects the automotive trend towards more efficient, reliable, and low-maintenance steering systems. EPS technology has proven itself in many modern vehicles for these reasons. As a driver, this means less hassle with pump replacements or fluid leaks and more time enjoying the road.
