Power Steering Pump on the 2018 Subaru Exiga: What You Need to Know

The 2018 Subaru Exiga is a popular choice for many drivers looking for a reliable and spacious vehicle. When discussing the power steering system on this model, it's important to first clarify whether the 2018 Exiga actually uses a power steering pump.

Based on technical data and official specifications, the 2018 Subaru Exiga employs an Electric Power Steering (EPS) system rather than a traditional hydraulic power steering system. This means that it does not use a power steering pump at all. Instead of relying on a hydraulic fluid-driven pump to assist steering, the steering assistance is provided electronically by an electric motor controlled by the vehicle's computer system.

So why does the 2018 Subaru Exiga not use a conventional power steering pump? There are a few key reasons behind this choice. Firstly, electric power steering systems are becoming increasingly popular in modern vehicles due to their efficiency and improved fuel economy. Traditional power steering pumps draw power from the engine via a belt, which adds parasitic drag and slightly reduces fuel efficiency. An EPS system eliminates this since it only uses power when the driver is steering.

Additionally, electric power steering systems typically require less maintenance compared to hydraulic systems. With a hydraulic setup, there is always the risk of fluid leaks, pump wear, and the need to periodically replace power steering fluid. Electronic systems remove those concerns and provide precise control over steering effort, often resulting in better steering feel and responsiveness.

While there is no power steering pump on the 2018 Subaru Exiga, understanding the role of this component is useful for those curious about steering systems or comparing different models. Traditionally, a power steering pump plays a crucial role in hydraulic power steering systems, so imagine a simple mechanical pump driven by the engine belt. This pump pressurises power steering fluid and delivers it to the steering gear, which significantly reduces the effort needed by the driver to turn the steering wheel. This makes parking, low-speed manoeuvres, and cornering much easier and more comfortable.

If the 2018 Subaru Exiga were equipped with a hydraulic power steering pump, regular maintenance would be important to keep it running smoothly. Maintenance typically includes checking and topping up the power steering fluid level, inspecting hoses and seals for leaks, and listening for any unusual noises coming from the pump. A whining or groaning sound could indicate the pump is failing or fluid is running low, which should be addressed promptly to avoid steering issues.

In vehicles with a traditional power steering pump, replacement of the pump might be necessary after years of use or if it develops faults. This usually involves draining the power steering fluid, disconnecting the pump from the engine and steering system, and then installing a new pump followed by refilling and bleeding the hydraulic system to remove air bubbles.

For the 2018 Subaru Exiga's electric power steering system, although there is no pump or hydraulic fluid to worry about, regular servicing is still important. This mostly involves diagnostics during scheduled maintenance to ensure the EPS motor and sensors are functioning correctly. If there are any electronic faults or abnormal steering behaviour, technicians can use specialised scan tools to identify and address any issues.

Owners of the 2018 Subaru Exiga can appreciate that by opting for an electric power steering system, Subaru has minimised the maintenance requirements typically associated with power steering pumps. It also brings modern benefits such as improved fuel economy and the potential for variable steering assistance that adapts to driving conditions or speed.

To keep the steering system in good shape on your Exiga, it's wise to follow SUBARU's recommended service intervals and have qualified professionals check the EPS system components as part of your regular servicing routine. While you won't ever need to worry about a worn-out power steering pump, staying on top of any warning lights or unusual steering sensations will help ensure a safe and comfortable driving experience for years to come.

In essence, the 2018 Subaru Exiga does not use a power steering pump because it utilises an electric power steering system. This modern approach eliminates many of the traditional maintenance concerns linked to hydraulic power steering pumps while offering efficient, responsive steering assistance tailored to driver needs.
