FAQ - Answer 1 | No. It is not necessary to regularly check power steering fluid unless there is a leak suspected in the system or an unusual noise is heard. Fluid loss in this system could indicate a problem, and you should have the system inspected and repaired if you find evidence of a loss. Always reference your vehicle's service information for appropriate maintenance intervals. |
FAQ - Answer 2 | No. You will be able to steer your vehicle if the power steering goes out, but it will require more effort, especially at lower speeds. If your power steering goes out, have the system inspected and repaired as soon as possible. |
FAQ - Answer 3 | Yes. The power steering fluid should be flushed whenever a component is being replaced or the system has become contaminated. |
FAQ - Answer 4 | Yes. Use of the incorrect fluid may damage the vehicle, and the damages may not be covered by the vehicle or component's warranty. Always use the correct fluid listed in the manufacturer's service literature. |
FAQ - Question 1 | Do I need to change my power steering fluid regularly, even if there are no symptoms of problems with the system? |
FAQ - Question 2 | Will I be unable to steer my vehicle if my power steering goes out? |
FAQ - Question 3 | Should my power steering system be flushed every time it undergoes maintenance or component replacement? |
FAQ - Question 4 | Can using the incorrect fluid cause damage to my power steering system? |
Good Maintenance Practices - Section 1 - Bullet 1 | Check power steering fluid levels periodically and add fluid when necessary. |
Good Maintenance Practices - Section 1 - Bullet 10 | Always follow the manufacturer's specific instructions on flushing, but remember the following: always flush out the power steering fluid in the lines before removing the old pump and be ready with two or more quarts of power steering fluid for the flushing process. |
Good Maintenance Practices - Section 1 - Bullet 2 | Have your vehicle inspected if it exhibits any of the following symptoms: unusual noise when turning the steering wheel, a shimmy or shake in the steering wheel, heavy or unresponsive steering at low speeds or during parking lot maneuvers, and/or the steering wheel does not properly return to center. |
Good Maintenance Practices - Section 1 - Bullet 3 | If you live in areas that experience harsh, winter weather, have the entire steering system inspected before winter arrives to help ensure safer driving. |
Good Maintenance Practices - Section 1 - Bullet 4 | It is a good idea to replace O-rings when doing any steering system service. Reusing old O-rings can cause leaks. |
Good Maintenance Practices - Section 1 - Bullet 5 | Always check the specific manufacturer's service information for the correct power steering fluid to use. |
Good Maintenance Practices - Section 1 - Bullet 6 | Keep in mind that fluid color is not an indication of fluid condition. |
Good Maintenance Practices - Section 1 - Bullet 7 | After any service of the power steering system, always bleed the air from the system and verify proper system operation. An accurate fluid level cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise as well as pump damage over a period of time. |
Good Maintenance Practices - Section 1 - Bullet 8 | The most significant root causes of power steering failures that could lead to pump replacement are system contamination, improper pulley installation, and using the wrong fluid. Following the recommended service procedures during power steering pump replacement address these root causes and help ensure the longevity of the new power steering pump while reducing the chances of premature pump failure. |
Good Maintenance Practices - Section 1 - Bullet 9 | Flushing the system will help eliminate any residual contaminants from causing future pump failure. Dirty or contaminated fluid may cause low or no pressure from the power steering pump, causing the relief valve to stop functioning. |
