Power Steering Fluid for the 2017 Holden Astra: What You Need to Know

The 2017 Holden Astra is a popular compact car in Australia, known for its efficient performance and modern features. If you're curious about whether this model requires power steering fluid, it's important to understand how its steering system works to determine if power steering fluid is relevant or not.

When it comes to power steering systems, there are generally two types: hydraulic and electric. Hydraulic power steering uses power steering fluid to transfer force within the system, helping the driver steer the vehicle with less effort. An electric power steering system, on the other hand, uses an electric motor to assist the driver and does not require any fluid at all.

For the 2017 Holden Astra, Holden actually fitted electric power steering (EPS) to this model rather than a traditional hydraulic system. This means the steering assistance comes from an electric motor connected to the steering column, which controls the amount of help provided based on driving conditions and speed. Because it uses an electronic setup instead of a hydraulic pump and fluid lines, there is no power steering fluid tank and no fluid to change or top up.

Why choose electric power steering instead of hydraulic? There are a few reasons. Electric power steering systems are generally more fuel efficient since they don't rely on a hydraulic pump running off the engine's crankshaft. This reduces parasitic engine loss and improves overall fuel economy. EPS is also lighter and requires less maintenance because there are no hoses or fluids that can leak or degrade over time.

This makes the 2017 Holden Astra a pretty slick example of modern steering technology. Drivers won't have to worry about checking or topping up power steering fluid because there simply isn't any in the system. The electric power steering motor and associated electronics are designed to be largely maintenance-free and built to last the lifetime of the vehicle under normal use.

That said, it's still important to keep the steering system in good shape. Here are some tips for maintaining your Astra's power steering system despite the absence of fluid:

• Listen for unusual noises: If the steering starts getting noisy, stiff, or feels jerky, it might indicate a problem with the electric motor or sensors.
• Watch for warning lights: Modern cars like the Astra will display a warning or fault light on the dash if the electric power steering system detects an issue.
• Steering feel: If the steering suddenly becomes very heavy or unresponsive, it's a sign to get the system inspected by a professional technician.
• Keep tires and suspension in check: Properly maintained tyres and suspension help the steering system perform optimally and prevent undue strain on the electric motor.

If any problems are suspected with the electric power steering system, it's best to have it checked by an authorised Holden service centre or a qualified mechanic with experience in modern steering electronics. Because the system is electric, repairs can often involve checking sensors, wiring, and control modules rather than fluid leaks or mechanical pumps.

One of the perks of the electric power steering in the 2017 Holden Astra is that it also often provides adaptive or variable steering assist. This means the level of steering help adjusts automatically based on things like vehicle speed or driving style, improving handling and comfort. This kind of advanced setup wouldn't be possible with traditional hydraulic systems relying on fluid.

To recap, the 2017 Holden Astra does not use power steering fluid because it replaces the old hydraulic system with an electric power steering motor and sensors. This design choice offers benefits in fuel efficiency, reduced maintenance, and enhanced driving experience. While no power steering fluid servicing is needed, staying alert to noises, warning lights, and steering responsiveness will help keep the steering system working well for years to come.
