Power Steering Fluid and the 2018 Toyota Hilux: What You Need to Know

The 2018 Toyota Hilux is well-known for its ruggedness, reliability, and capable performance on and off the road. When it comes to the power steering system on this model, many wonder whether power steering fluid is involved and how important it is to maintain. After checking the technical specifications from Toyota and trusted automotive sources, it turns out that the 2018 Hilux does not use traditional power steering fluid in the way many older hydraulic steering systems do.

The reason the 2018 Toyota Hilux does not rely on power steering fluid is that most versions of this vehicle come equipped with an electric power steering system rather than a hydraulic one. Instead of a hydraulic pump driven by the engine and fluid circulating to assist steering effort, the electric power steering (EPS) system uses an electric motor controlled by sensors to provide steering assistance. Because EPS does not use hydraulic fluid to operate, there is no need for power steering fluid or fluid maintenance in this setup.

So why do some vehicles still use power steering fluid? Traditional hydraulic power steering systems rely on a pressurised fluid that flows through the system to help reduce the effort needed to steer the vehicle. This fluid lubricates moving parts, transfers power from the steering pump to the steering gear, and helps cool components. Over time, this fluid can degrade, develop contaminants, or leak, making it important to periodically check and replace it to maintain smooth steering performance and avoid damage to the system.

With the rise of electric power steering like in the 2018 Hilux, many models have moved away from the traditional hydraulic system to cut down on mechanical complexity, improve fuel efficiency, and offer more precise control. Electric power steering systems are generally more reliable since they have fewer moving parts and don't rely on fluid that can leak or degrade. This reduces the need for fluid checks and replacements, simplifying maintenance.

Even though the 2018 Toyota Hilux does not require power steering fluid, it is still important to keep an eye on the entire steering system as part of regular servicing. While you won't be topping up fluid, the steering components such as linkages, joints, and racks should be inspected for wear and tear, damage, or unusual noises. This helps ensure the Hilux maintains that smooth, responsive steering feel that drivers expect when navigating tricky terrain or city streets.

In vehicles where power steering fluid is used, maintenance usually involves checking the fluid level in a reservoir under the bonnet and topping up if necessary. Over time, complete flushes of the power steering fluid may be recommended to remove old contaminated fluid and replace it with fresh fluid. This helps protect seals, pumps, and hoses, preventing premature failure and maintaining consistent steering assist.

Some practical tips if your vehicle does use hydraulic power steering fluid include:

• Regularly inspect the fluid level and condition, ideally every 10,000 to 20,000 kilometres.
• Use the fluid type specified by the vehicle manufacturer - this varies between models and using the wrong fluid can cause damage.
• Watch for leaks around hoses, pumps, and steering racks, which might show up as low fluid levels or steering noise.
• If the steering becomes noisy, stiff, or unresponsive, it could be a sign the fluid needs replacement or the system requires repair.
• Have fluid checked and replaced as part of scheduled servicing to keep the system working smoothly.

But since the 2018 Toyota Hilux uses electric power steering, owners are spared the hassle of fluid maintenance. This modern system also means fewer potential points of failure - no hydraulic hoses to leak or pumps to wear out from fluid contamination. Instead, any steering concerns should be addressed by inspecting electrical components, motors, and sensors involved in the EPS setup.

So for anyone driving a 2018 Hilux, it's good to know that power steering fluid is simply not part of the equation. While traditional fluid checks and changes are essential for cars with hydraulic power steering, the Hilux keeps it straightforward with electric steering assistance. Keeping up with regular inspections and servicing will still ensure the Hilux delivers that confident steering response it's praised for, whether tackling off-road trails or daily driving.
