The Ultimate Guide to Your MPS Power Steering Pump

Nothing should stand between you and that exhilarating drive when you slide behind the wheel. Yet, have you ever noticed a slight tug in your steering or an unwelcome noise when navigating tight corners? Enter the unsung hero of your vehicle’s performance—the power steering pump. For those who crave smooth handling and effortless maneuverability, understanding your MPS Power Steering Pump is not just beneficial; it’s essential. In this guide, we’ll demystify everything from its vital components to signs of wear—and even how to keep it purring like a well-oiled machine.

What is a Power Steering Pump?

A power steering pump is crucial to your vehicle’s power steering system. It is the primary source of hydraulic pressure that helps the driver turn the wheels with minimal effort. Without this pump, maneuvering your car would become extremely difficult and tiresome.

At its core, a power steering pump is essentially a tiny rotor driven by an engine or serpentine belt. This rotor is housed within a chamber filled with hydraulic fluid and has small vanes attached. As the engine turns, these vanes spin along with the rotor. This action draws the pressurised fluid from the reservoir through an inlet pipe and pushes it out through an outlet pipe towards the power steering gear.

The amount of fluid being pumped varies depending on how much assistance is required for each steering wheel turn. When making sharp turns, more fluid will be pushed out at higher pressures than when making wide turns, where less fluid will be needed.

The pressure created by the rotating vanes inside the pump creates resistance against which you can comfortably steer your vehicle without exerting too much effort. Remember that while turning, some energy is lost due to friction between moving parts within the pump and hoses, so it’s essential to have enough pressure for efficient operation.

Signs of a Failing Power Steering Pump

A power steering pump is vital to your vehicle’s power steering system, providing the necessary hydraulic pressure to help you quickly turn your wheels. However, like any other mechanical part, it can fail over time due to wear and tear or lack of maintenance. It is crucial to be aware of the signs that indicate a failing power steering pump so that you can address the issue before it becomes a significant problem.

1. Difficulty Turning the Steering Wheel

One of the most noticeable signs of a failing power steering pump is difficulty turning the steering wheel. Suppose you exert more effort than usual to steer your car, especially at low speeds or when parking; it could be due to a malfunctioning pump. This could be caused by a leaking or clogged fluid line or worn-out internal components within the pump.

2. Whining Noise

A common symptom of a failing power steering pump is a whining noise under the hood while turning the wheel. This noise may get louder as you accelerate, even when your car is idle. The sound indicates that air has entered the system through leaks or insufficient power steering fluid for smooth operation.

3. Excessive Vibration

A power steering pump provides steady and constant pressure, allowing for smooth handling and minimal vibration while driving. If you notice excessive vibrations in your car’s steering wheel, it could indicate that something is wrong with your power steering system – specifically, with the pump.

How Does the Mazda 6 Power Steering Pump Work?

The Mazda power steering pump plays a crucial role in ensuring the smooth and effortless operation of your vehicle’s steering system. This component provides pressurised hydraulic fluid to assist in turning the wheels. In this section, we will explore how exactly it works.

To understand the power steering pump’s functionality, it’s essential to first understand how the entire steering system operates. The Mazda 6 utilises a rack-and-pinion steering system with multiple components to allow you to turn your wheels quickly.

Turning your car’s steering wheel triggers a series of actions that ultimately lead to turning the wheels. The power steering pump uses an engine-driven belt or pulley to generate pressure that forces hydraulic fluid through hoses and into the rack and pinion mechanism. This creates a force on each rack end, allowing smooth turning movement.

Inside the Mazda 6 Power Steering Pump are various components that work together seamlessly to achieve this pressurisation. The primary element is a rotary vane assembly – essentially a rotor with attached vanes that rotates inside an electric motor or belt-driven housing. As this rotor spins, centrifugal force pushes against the vanes, creating suction on one side and compression on the other.

How to Maintain Your Power Steering Pump?

Regular maintenance of your power steering pump is crucial to ensure its optimal performance and longevity. Neglecting the necessary upkeep can lead to various issues, such as leaks, noise, and even complete pump failure. To avoid these problems and keep your power steering system running smoothly, follow these simple steps for maintaining your power steering pump.

1. Check the Power Steering Fluid Regularly

The first step in maintaining your power steering pump is to regularly check the level and condition of the power steering fluid. The fluid keeps all the moving parts inside your pump lubricated, preventing wear and tear. Low levels of dirty fluid can damage the internal components of the pump. It is recommended that you inspect the fluid every time you open your car’s hood, especially before long drives.

2. Replace Old Power Steering Fluid

Over time, the power steering fluid gets contaminated with dirt and debris from within the system. This can cause irreversible damage if not addressed promptly. It’s essential to replace old fluid with fresh one according to manufacturer recommendations (usually every two years). Flushing out old and dirty fluid will help maintain the proper functioning of your power steering system.

3. Keep an Eye on Belt Tension

Your power steering pump relies on a belt that rotates every time you turn your car’s wheel. Over time, this belt may become loose or worn out due to constant use and exposure to heat under the hood. A slack or damaged belt will affect the unit’s pumping action, resulting in reduced performance or even failure over time. Inspecting and tightening loose belts ensures smooth operation without straining other components.

Upgrading Your Power Steering System

While the power steering pump is designed to provide efficient assistance, upgrading your power steering system can further enhance its performance and longevity. Upgrading your power steering system involves replacing or adding components such as hoses, belts, reservoirs, and fluid to improve your vehicle’s power steering functionality.

One of the most common upgrades for a power steering system is replacing old or damaged hoses. Over time, these hoses can wear out and develop cracks or leaks, which can lead to loss of hydraulic pressure and inefficient power steering functioning. It is recommended to replace these hoses every 50,000 miles or if you notice any signs of wear and tear. When selecting new hoses for your power steering pump, be sure to opt for high-quality variations designed specifically for your vehicle’s make and model.

Another critical component of a well-functioning power steering system is the belt. The belt connects the engine to the power steering pump and transfers rotational force from the engine to generate the hydraulic pressure needed for smooth steering. Over time, this belt may deteriorate due to constant tension and exposure to heat from the engine. Regularly checking and replacing this belt can help maintain a reliable and efficient power steering system.

In addition to maintenance items like hoses and belts, upgrading your fluid reservoir can improve overall performance. It may be time to upgrade if you notice any signs of contamination in your current reservoir, such as debris or discoloured fluid. A fresh reservoir with clean fluid will ensure optimal performance and protect other components within the system from damage.
