Parts for your 2018 Mazda Cx-5-Power steering pump

Understanding the Power Steering Pump on the 2018 Mazda CX-5

The 2018 Mazda CX-5 is equipped with a power steering system designed to make manoeuvring easier and more comfortable for drivers. Specifically, this model utilises an electric power-assisted steering (EPAS) system rather than a traditional hydraulic power steering pump. This means there is no conventional power steering pump fitted to the vehicle.

So why doesn't the 2018 Mazda CX-5 use a power steering pump like older or other vehicles? The main reason comes down to efficiency, reliability and modern technology trends. Traditional hydraulic power steering systems rely on a pump driven by the engine via belts. This pump pressurises hydraulic fluid which assists in turning the steering gear. While effective, this system has drawbacks such as constant engine load, potential leaks from hoses or seals, and the need for regular maintenance like fluid changes.

The 2018 CX-5 uses an electric power-assisted steering system which replaces the hydraulic pump with an electric motor mounted on the steering rack. This motor provides assistance by reducing steering effort through electronic control, drawing power only when needed. This results in better fuel efficiency since the engine isn't constantly powering a hydraulic pump. It also means less maintenance and fewer components that might fail or leak over time.

Because of this modern steering setup, owners do not need to worry about servicing or replacing a power steering pump on their 2018 Mazda CX-5. Instead, the EPAS system is generally maintenance free. However, it is still important to keep an eye out for any signs of steering issues or warning lights that might suggest problems with the electronic assist system or related components.

Here are some reasons why Mazda opted for an electric power-assisted steering system on the 2018 CX-5:

• Improved fuel economy by eliminating the engine-driven hydraulic pump load
• Reduced system complexity and maintenance requirements
• More precise steering feel that can be tuned electronically
• Safer operation with integrated electronic controls and diagnostics
• Lighter overall system contributing to vehicle weight reduction

For drivers who are used to the old style hydraulic power steering pump, this EPAS system might feel different at first but it generally offers a smooth and responsive steering experience. Because there is no hydraulic fluid or pump, there is no need for periodic power steering fluid checks or pump replacements.

If a driver does experience any steering difficulties such as heavier steering effort, unusual noises from the steering column, or warning lights on the dashboard related to the steering system, it is best to have the car checked by an authorised Mazda service centre. They can perform diagnostic tests on the electric power steering system components including the motor, sensors and control modules.

Overall, the move away from hydraulic power steering pumps in vehicles like the 2018 Mazda CX-5 is part of a wider automotive trend towards more efficient, reliable, and environmentally friendly systems. Even though replacing or maintaining a conventional power steering pump doesn't apply here, keeping the entire steering system in good working order remains essential for safety and driving enjoyment.

Owners looking after their 2018 Mazda CX-5 should follow the manufacturer's recommended service schedule and let trained technicians handle any steering-related inspections or repairs. This will ensure the electric power steering system continues to provide the smooth and effortless control that Mazda intended, mile after mile.
