New to this forum and appreciate any guidance the group can provide.
I have a 2008 MDX with approximately 160k miles. Always well maintained at either Acura dealer or Honda/Acura certified specialist. I was told the power steering pump appears to have a very slow leak which has worsened over the past few months oil stains wherever I park and a slowly draining power steering reservoir. I was quoted ~$600 to replace. Another mechanic mentioned it could be the O ring and would be far less $. Has anyone had any luck with replacing the O rings on the 2008 MDX? Not a fan of after market parts but looking to save $.

Appreciate any recommendations. Thanks!

Sure. It's a $10-15 worth of two new O-rings job you can do yourself.

Here's my video on it:

Wilsoncc and AcuraAddicted are right. The internal seals are cheap and easy to be replaced.


If the leak is also coming from the front of the PS pump by the pulley, you need to replace the front oil seal and bearing.

If it were mine I would do the O ring and see if that solves the issue. If not I would then clean the area as well as I can with engine degreaser, add some dye to the PS reservoir, and use an ultraviolet flashlight to see if I could identify the cause. Of course you could start with cleaning and the dye, but with the O ring being a common issue and a cheap guess that's not a bad place to start. If you put dye in then it's best to be checking with the ultraviolet light ASAP before it gets all over the place making it harder to determine the source. Put the dye in, start the car and let it idle, and begin watching with the light to see where it first shows up.
