Power Steering Fluid and the 2019 Subaru Legacy: What's the Story?

When it comes to the 2019 Subaru Legacy, one might wonder about the role of power steering fluid. Interestingly, the 2019 Subaru Legacy doesn't use traditional power steering fluid. Instead, it features an electric power steering (EPS) system. This marks a significant shift from the hydraulic power steering systems found in older vehicles, which relied on fluid to assist in steering.

This transition to electric power steering isn't unique to the Subaru Legacy. Many modern vehicles have swapped out hydraulic systems in favour of electric ones for several compelling reasons. First and foremost, electric power steering systems are generally more efficient, as they don't depend on a constantly running pump. This improvement results in better fuel economy, as the system only uses power when steering assistance is necessary.

Furthermore, the electric system setup leads to reduced maintenance needs. There's no power steering fluid to check or replace, eliminating potential leaks or contamination issues common in hydraulic systems. This change enhances reliability and longevity. The vehicle's steering becomes more predictable and consistent, contributing to a smoother overall handling experience.

That being said, for those familiar with older hydraulic systems and the role of power steering fluid, the absence might seem a little odd. So, what was the purpose of power steering fluid in those systems, and what did maintenance entail?

In traditional hydraulic power steering systems, power steering fluid played a crucial role. This specially designed oil worked as a lubricant, allowing various components to operate smoothly. It was also responsible for transmitting the hydraulic pressure needed to assist in steering, making turning the wheel less of an arm workout.

Proper maintenance of power steering fluid was key. Over time, the fluid could break down or become contaminated with dirt and metal particles, reducing its effectiveness. Drivers might notice stiffer steering, squealing noises, or even find a puddle of the stuff beneath their vehicle - none of these are ideal situations.

The standard advice for those with hydraulic systems was to regularly check the fluid level and condition. This could be done by locating the power steering pump reservoir under the bonnet and ensuring the fluid is within the appropriate marks, typically using a dipstick attached to the cap. Checking the colour and smell of the fluid was also a smart move. Fresh fluid is usually clear or light amber, while old fluid could be dark and burnt-smelling.

As for fluid replacement, it was often recommended to change it every 50,000 to 100,000 kilometres, depending on the vehicle and driving conditions. This interval ensured that the system remained in good shape and provided optimal steering assistance. However, it was always wise to consult the vehicle's owner's manual or a trusted mechanic for specifics.

Maintaining the hydraulic power steering system also typically involved inspecting the hoses and seals for signs of wear, as these were common sources of leaks. Addressing any issues promptly was important to avoid further complications or costly repairs.

But let's not dwell too much on the what-ifs. Returning to the electric power steering system found in the 2019 Subaru Legacy, there's freedom from those particular maintenance tasks associated with power steering fluid. Drivers can relish the reduced maintenance requirements and appreciate the more fuel-efficient and environmentally friendly technology supporting their daily drives.

The EPS system in the Subaru Legacy contributes significantly to a quieter, more efficient operation while delivering a comfortable steering feel. Drivers benefit from a system that's closely integrated with the vehicle's other electronics, offering a refined and responsive driving experience whether they're navigating busy city streets or enjoying a long country drive.

Although there's no power steering fluid to fuss over, regular vehicle maintenance remains just as important. Looking after components like the tyres, brakes, and other essential systems continues to be crucial for safety and performance. This ensures the 2019 Subaru Legacy remains a reliable and enjoyable companion on the road for years to come.
