Power Steering Pump on the 2016 Subaru Legacy: What You Need to Know

The 2016 Subaru Legacy is a popular mid-sized sedan known for its reliability, safety features, and smooth driving experience. When it comes to steering, this vehicle does indeed have a power steering system, but it's important to clarify what type of system it uses and whether a traditional power steering pump is part of it.

The 2016 Subaru Legacy is equipped with an Electric Power Steering (EPS) system rather than a conventional hydraulic power steering system. This means it does not use a power steering pump in the traditional sense. Instead of relying on a pump driven by the engine to pressurise hydraulic fluid and assist steering, the EPS system uses an electric motor to provide steering assistance. This system enhances fuel efficiency and reduces maintenance needs because it does not require hydraulic fluid or a hydraulic pump.

Why does the 2016 Subaru Legacy rely on an Electric Power Steering system rather than a hydraulic one with a power steering pump? There are a few key reasons. Firstly, EPS systems are more fuel-efficient since they eliminate the parasitic drag from a belt-driven hydraulic pump. Hydraulic pumps run constantly when the engine is on, which uses energy even when steering assistance is not required. Electric systems deliver assistance only when needed, saving fuel and reducing emissions.

Secondly, EPS systems reduce complexity and maintenance. Traditional power steering pumps require regular checks of hydraulic fluid levels and periodic fluid changes to prevent wear and leaks. Hydraulic hoses and seals can deteriorate over time, causing leaks and steering issues. Electric power steering systems avoid these problems since there is no fluid to maintain or pump to replace. This makes EPS systems more reliable and less costly to maintain in the long term.

So, if a 2016 Subaru Legacy does not use a power steering pump, what does that mean for the owner in terms of servicing and maintenance? While there is no pump to service or replace, the electric power steering system still demands some attention to ensure it remains in good working order. Steering components such as the steering rack, tie rods, and mounts all require periodic inspection. Additionally, any electrical problems affecting the power steering motor or sensors will need diagnosing and repair by a qualified technician.

For those looking for information about power steering pumps and their role on vehicles that have them, here is a closer look at the power steering pump purpose and maintenance - bearing in mind this does not apply directly to the 2016 Subaru Legacy's system.

A power steering pump is a key part of a hydraulic power steering system. It is usually belt-driven from the engine and works by circulating power steering fluid under pressure to the steering gear. This pressurised fluid assists the driver in turning the steering wheel with less effort, especially at low speeds, such as when parking or manoeuvring tight corners. The pump plays a vital role in making steering easier, safer, and more comfortable.

When servicing a car with a hydraulic power steering system, the pump often requires inspection and potentially replacement if it's worn or leaking. Signs of a failing power steering pump can include whining or groaning noises when turning the wheel, stiff or unresponsive steering, fluid leaks under the vehicle, or a burning smell from the pump overheating. Early detection of these symptoms can prevent costly repairs and ensure continued safe steering performance.

Routine maintenance for hydraulic systems involves checking power steering fluid levels, topping up with the correct fluid type, and flushing the system periodically to remove contaminants and old fluid. Worn belts driving the pump should also be inspected and replaced as necessary to avoid pump failure. Replacing a faulty power steering pump restores proper fluid pressure and steering assist, improving handling and driver confidence on the road.

For 2016 Subaru Legacy owners, understanding the differences between EPS and hydraulic power steering systems is important. While they won't need to worry about the traditional pump maintenance, they should keep an eye on the overall steering system health. Regular service inspections by trusted mechanics ensure that the electric power steering motor assembly and related steering components are functioning correctly, prolonging the lifespan of this modern steering technology.

In short, although power steering pumps are a critical part of many vehicles with hydraulic power steering, the 2016 Subaru Legacy skips the pump in favour of a more efficient and low-maintenance electric system. This choice reflects Subaru's focus on combining performance, efficiency, and reliability for everyday drivers. So Legacy owners can enjoy smooth steering and peace of mind without the hassle of power steering pump upkeep.
