I. How Often Should Power Steering Fluid Be Changed?
Power steering fluid also has a usage period or mileage limit. When it reaches these limits, it needs to be changed. Generally, it is recommended to change power steering fluid every 40,000-50,000 kilometers or every 2-3 years.
Power steering fluid is actually transmission fluid, mainly used for lubricating the steering wheel. Often, after a long period of use, the steering wheel will not be as easy to control as before. This is usually caused by insufficient lubrication. Adding power steering fluid will solve this problem.
II. How to Determine if Power Steering Fluid Needs Changing
1. Check the Power Steering Fluid Level
Locate the power steering fluid reservoir in the engine compartment and observe the fluid level through the sight glass. If the fluid level is below the minimum mark, power steering fluid needs to be added.
2. Observe the Fluid Color and Condition
Normal power steering fluid should be clear and transparent, without impurities or sediment. If the fluid becomes cloudy or contains impurities, it needs to be changed.
3. Smell the Power Steering Fluid
Normal power steering fluid should have no noticeable odor. A pungent smell indicates the fluid has deteriorated and needs replacement.
4. Check the Steering System’s Operation
Start the car and test the steering system. Heavy or sticky steering may indicate the power steering fluid needs changing.
III. How to Change the Power Steering Fluid
- To reduce the burden of changing the power steering pump, use two jacks to lift the front wheels of the car. Remember to engage the handbrake.
Next, drain the power steering fluid. Use pliers to disconnect the return hose (do not use excessive force to avoid damaging the connector) and place the return hose in a waste bottle. It’s best to cover the outlet of the reservoir to prevent leaks.
Now start the vehicle and turn the steering wheel left and right to drain the old power steering fluid. Simultaneously, add new fluid to the reservoir. If the drained power steering fluid is relatively clean, it means the fluid has been completely drained.
Finally, reinstall the oil hose (with the engine off) in reverse order, and add new power steering fluid until the level reaches the maximum mark. Of course, you should also start the car and turn the steering wheel left and right to allow the power steering fluid to circulate for a while. At this time, the power steering pump may make some strange noises; this is normal as it draws in and expels new fluid.
IV. Where to Add Power Steering Fluid
The power steering fluid reservoir is usually located on the left side of the engine compartment, near the dipstick. The reservoir cap will have a steering wheel symbol; finding this cap will indicate the exact fluid level. Opening the reservoir cap will reveal a gauge with maximum and minimum fluid level markings. These markings will guide you through the process, indicating the correct level to fill with the power steering fluid; do not overfill.
