Power Steering Fluid for the 2019 Mazda CX-5: What You Need to Know

When it comes to the 2019 Mazda CX-5, understanding whether or not it requires power steering fluid is essential for proper maintenance. Many people assume all cars with power steering systems need regular topping up or replacement of power steering fluid, but that isn't always the case. The reality for the 2019 Mazda CX-5 is quite different, thanks to the technology Mazda has integrated into their steering system.

The 2019 Mazda CX-5 does not use traditional hydraulic power steering fluid because it features an Electric Power Assisted Steering (EPAS) system. Unlike older systems that rely on hydraulic fluid to assist steering, this setup uses an electric motor to provide the necessary steering assistance. This means there is no reservoir for power steering fluid and no need to check, top up or replace any fluid as part of the vehicle's regular servicing schedule.

Electric Power Assisted Steering is more efficient and maintenance-friendly when compared to hydraulic systems. Without fluid, there's no risk of leaks or degradation of fluid quality, and this contributes to a cleaner under-bonnet layout and a simpler overall system. EPAS also allows for more responsive steering and improved fuel economy, as the electric assist only draws power when steering input is needed rather than running continuously like a hydraulic pump.

If a 2019 Mazda CX-5 owner is wondering about any signs related to the power steering system, such as unusual noises or heavy steering feel, the issue likely isn't related to fluid levels. Instead, any problems would be more related to the electric components or sensors in the system. In this case, a qualified Mazda technician would be able to diagnose the problem using specialised diagnostic tools rather than looking for fluid shortages or leaks.

However, if someone owns an older Mazda or another vehicle with a conventional hydraulic power steering system, knowing all about power steering fluid is a must. For those curious about what power steering fluid does and how to maintain it properly, here's a general look into power steering fluid's role and care, keeping in mind that this information does not apply to the 2019 Mazda CX-5.

Power steering fluid is a specialised hydraulic fluid responsible for transmitting the power in a hydraulic steering system. When the driver turns the steering wheel, the fluid transfers that motion via the power steering pump and rack to help turn the wheels with much less effort than a manual steering system. This fluid lubricates moving parts within the system and helps prevent corrosion, oxidisation and wear inside the power steering pump, hoses, and rack and pinion unit.

As fluid ages and heats up, it can become contaminated with moisture and metal particles, which reduces its effectiveness and can start to damage the system's components. That's why old or degraded power steering fluid should be replaced regularly to keep the steering feeling smooth and responsive.

Generally, maintaining power steering fluid involves:

• Checking the fluid level regularly using the reservoir dipstick or sight window.
• Inspecting the fluid colour and condition. Healthy power steering fluid tends to look clear or a light amber colour. Dark, cloudy or burnt-smelling fluid signals it's time for a change.
• Replacing the fluid as recommended by the manufacturer, which is often around every 50,000 kilometres or so, though intervals can vary.
• Inspecting hoses and seals for leaks, as fluid leaks cause loss of pressure, which affects steering assistance.

When it comes time to replace the fluid, it's important to use the correct type recommended by the vehicle manufacturer, whether that be DOT 3, DOT 4 brake fluid (in some special systems) or a dedicated power steering fluid. Using the wrong fluid can damage the seals and internal components, leading to costly repairs.

Bleeding the system after fluid replacement ensures that any air trapped inside is removed, because trapped air can cause noise and reduce steering efficiency. Such maintenance should ideally be carried out by professionals to avoid damage or suboptimal performance.

Ultimately, for anyone with a 2019 Mazda CX-5, there's peace of mind knowing there is no need to worry about power steering fluid at all. The electric power steering system offers a fuss-free experience without the common maintenance concerns associated with hydraulic fluid. Just keep up with the standard servicing schedule, and should any steering-related issues arise, get the system inspected by a Mazda specialist to ensure the electric components are performing as expected.
