Power Steering Fluid - JAX Service Inclusion

As a general guideline, replacing the power steering fluid every 50,000 to 95,000 kilometres or every 2 years is often recommended.

However, the frequency of power steering fluid changes can vary depending on the specific vehicle and manufacturer's recommendations. You can find regular maintenance intervals and fluid change schedules in the vehicle's owner manual or, if you’re unsure, we recommend chatting with your local JAX mechanic, who can provide guidance on the appropriate maintenance schedule for your specific vehicle. 

If your power steering fluid is low, it can have several consequences on the performance and safety of your vehicle's steering system. Here are some potential issues that may arise:

• Increased steering effort: Power steering fluid reduces the effort required to turn the steering wheel. When the fluid level is low, manoeuvring the vehicle is more challenging, especially at lower speeds or during parking manoeuvres.
• Noisy steering operation: Due to a lack of proper lubrication, low fluid levels can result in a whining or groaning noise when you turn the steering wheel. 
• Poor steering response: Insufficient fluid can cause delayed or sluggish steering response compromising your ability to navigate corners or make quick manoeuvres.
• Potential damage to power steering components: Due to a lack of a proper lubrication barrier, friction and heat buildups within the system, potentially damaging these components over time.
• Leaks and contamination: Leaks can occur from deteriorated hoses, seals, or other components, causing low fluid levels. It's essential to address these leaks promptly to prevent further fluid loss and potential damage to the system.

It's important to note that driving with low power steering fluid levels for an extended period can cause severe damage to the power steering system, resulting in costly repairs. If you notice any of these systems, consult a qualified mechanic who will help diagnose the problem and ensure proper maintenance and repair of the power steering system.

Power steering fluids and automatic transmission fluids are both types of hydraulic system fluids however are distinct as manufacturers designed them to do separate tasks, so it can be dangerous to use one instead of the other.

The main difference is the inclusion of additives and detergents in the transmission, making it specialised for transmission use. Friction modifiers and detergents in transmission fluid are designed to avoid wear and tear on metal components, carry contaminants away, and cool the system. On the other hand, the power steering fluid does not contain these vital modifiers and detergents. These detergents may keep contaminants that work their way into the power steering system causing damage to the hydraulic valves which are part of the car’s steering rack

Like any other lubricant, power steering fluid accumulates wear material, moisture, and other debris and can wear out due to oxidation. All of which indicate the need for maintenance or fluid replacement. Here are some common symptoms of bad power steering fluid:

• The pump whines or makes a noise: If the power steering fluid is old or contaminated, you might hear a whining or groaning noise when turning the steering wheel. This noise can indicate a lack of proper lubrication or air bubbles in the system.
• Foamy or discoloured fluid: When inspecting the power steering fluid reservoir, if you observe foamy or aerated fluid or notice that the liquid has a dark or discoloured appearance, it indicates potential contamination or fluid breakdown.
• Burning smell: In extreme cases of power steering fluid deterioration or overheating, you may detect a burning smell from the engine compartment. This can result from excessive heat generated by friction or contamination within the power steering system.
• Jerky or inconsistent steering response: Deteriorated power steering fluid can lead to erratic or inconsistent steering response. 

If you experience any of these symptoms, we recommend contacting your local JAX store to have your power steering system inspected by a qualified mechanic. They can assess the condition of the fluid, identify any leaks or issues, and recommend the appropriate steps.

Yes, power steering fluid can go bad over time. 

While power steering fluid is designed to withstand high temperatures and provide long-lasting performance, it can still degrade and lose its effectiveness due to several factors:

• Contamination: Power steering fluid gets contaminated as parts of your system slowly wear out and deposit tiny particles in your fluid. As these particles build-up, it will turn the liquid a darker colour.
• Oxidation: Power steering fluid can oxidise when exposed to oxygen over an extended period. Oxidation can cause the liquid to thicken, lose its lubricating properties, and develop a dark or discoloured appearance.
• Moisture Absorption: Power steering systems are not completely sealed, and moisture can gradually enter the fluid. Moisture contamination can result in fluid degradation and reduce the fluid's ability to function optimally.
• Heat and Wear: The power steering system operates under high pressures and temperatures, which leads to the deterioration of the fluid's additives and properties, affecting its performance.

It is possible to change the power steering fluid yourself, although it requires some basic automotive knowledge and the right tools. Here's a general guide:

• Supplies: You'll need a replacement power steering fluid specific to your vehicle's make and model. You'll also need a funnel and a fluid pump to remove the old fluid.
• Locate the power steering fluid reservoir: The reservoir is typically located near the engine bay and labeled "Power Steering." 
• Ensure the engine is cool and turned off: Clean the area around the reservoir cap to prevent dirt or debris from falling into the system.
• Remove the old fluid: Use the fluid pump to extract the old liquid from the reservoir.
• Refill with fresh fluid: Pour the new power steering fluid into the reservoir using the funnel. Refer to the owner's manual for the recommended fluid level and type. 
• Bleed the system (if necessary): Some power steering systems may require bleeding to remove air pockets. Follow the specific instructions in your vehicle's owner's manual to perform this step correctly.
