How To Cheaply Fix a Noisy Honda Power Steering Pump

Power steering noise such as moaning or whining can be common and easily fixed for many Honda vehicles. For Honda vehicles, that are equipped with the power steering pump shown in the video, this noise is usually caused by old worn out O-rings that fit onto the suction and high pressure lines where they bolt up to the power steering pump.

Usually what happens is that these O-rings will allow air to be introduced into the power steering system and cause the power steering pump to cavitate. This is where the noise occurs.

"Burping the system": As mentioned in the video, once the power steering system has been filled you will need to start the engine and then turn the steering wheel to the left and right all the way from stop to stop. Shut the engine off. Check and adjust the fluid level as the level should have gone down. Repeat process until fluid is full and power steering system stops whining. Do not over fill the fluid reservoir. *Fluid level should always be checked and adjusted when the engine is off.* After the system has been filled to the correct level it may be necessary to continue turning the steering wheel from stop to stop several times to get all the air out.

If the system continues to whine after it is filled and the system has been bleed then the vehicle may be ingesting air into the system through another rout. Further repair will be needed.

This video is designed to help you to understand what may be the problem with your vehicle and also to help you to understand how to repair this problem.

Note: Please use care not to contaminate your drive belts with power steering fluid. If you do, it’s been my experience that quickly cleaning the belt with brake clean will help to prevent damage to the belt from oil contamination. However, it’s best to not even have to do that as brake clean is not great for the belt either but it will clean the belt.

The vehicle featured in the video is a 2005 Honda Odyssey Touring 3.5L

As promised the part #s for the o-rings are as follows
91370-sv4-000 and 91345-rda-a01
Both o-rings where purchased for just $6.52
