Parts for your 2017 Toyota Corolla-Power steering fluid

Power Steering Fluid and the 2017 Toyota Corolla

When it comes to the 2017 Toyota Corolla, many people wonder whether power steering fluid is part of the picture. Interestingly, this particular model does not actually use traditional power steering fluid because it's equipped with an electric power steering system rather than a hydraulic one. This means there isn't a power steering fluid reservoir or fluid to maintain, fill, or replace.

So why does the 2017 Toyota Corolla not use power steering fluid? The main reason lies in the technology behind the steering system. Earlier vehicle models often used hydraulic power steering, which relied on fluid to hydraulically assist the steering mechanism. These systems required power steering fluid to function smoothly, deliver the necessary assist, and reduce friction in the components.

However, the 2017 Corolla utilises electric power steering, sometimes referred to as EPS. Instead of a hydraulic pump and fluid, it uses an electric motor powered by the vehicle's battery to assist steering. This system is more efficient, lighter, and easier to maintain compared to hydraulic systems. Electricity replaces hydraulic fluid making the power steering fluid unnecessary.

Because there is no power steering fluid system in the 2017 Corolla, you won't find any power steering fluid to check or replace during regular servicing. You'll also avoid common issues involved with fluid leakage or contamination. This electric setup contributes to improved fuel economy and cleaner operation with less mechanical complexity.

For drivers curious about maintaining their steering system on a 2017 Toyota Corolla, maintenance is generally less hands-on regarding fluids. However, keeping the steering components themselves in good condition is still important. This includes regular checks on the steering rack, tie rods, and electric motor assist system during scheduled servicing. Wear and tear or electrical faults can still impact the steering feel or responsiveness, so technicians will look for any fault codes or mechanical issues.

Now, if one were to look at vehicles that do use power steering fluid, a little insight into that system can be handy. Power steering fluid is specially designed to transmit hydraulic pressure from the pump to the steering gear. It also lubricates the components and protects them against corrosion and wear. When maintained properly, power steering fluid enables smooth and responsive steering, making driving more comfortable and safer.

For vehicles with hydraulic power steering, fluid replacement is normally suggested as part of routine servicing, typically every 40,000 to 60,000 kilometres, or if the fluid becomes contaminated or degraded. Over time, power steering fluid can break down due to heat and use, potentially causing noisy steering, resistance, or even damage to the pump or hoses if left unchecked. Checking fluid levels regularly can prevent unexpected issues, and topping up is important if leaks are found.

While the 2017 Toyota Corolla skips the hydraulic fluid aspect, the switch to electric power steering aligns with broader industry trends aiming for more efficient, low-maintenance vehicle technology. It offers benefits like reduced weight, fewer moving parts, and less environmental impact, as there's no hydraulic fluid to dispose of. For Corolla owners, this means a little less hassle related to fluid checks and replacements, but always keep an eye on your vehicle's steering experience just in case.

So, if you're servicing a 2017 Toyota Corolla or simply taking care of it, power steering fluid is not something you will need to worry about. Instead, focus on general steering system health and the other fluid checks that the manufacturer recommends. Keeping an eye on tyre pressures, wheel alignment, and suspension components will also play a role in maintaining excellent steering performance overall.
