Hi all

Son in law has a 2007 MDX that is making a noise at the power steering pump area. At idle the noise is faint, but when turning the wheel the noise increases. The fluid in the reservoir is full, but bubbly and brown looking.

What do you guys think the issue could be? O rings on the inlets?

Thanks

I got the two new o rings and 3 bottles of Honda PS fluif; hoping to flush the old fluid and replace o rings this weekend. Can I use a Prestone Asian formula to flush with and fill with the Honda fluid?

Would the hose be 5/8 diameter?

Hond/Acura’s are real sensitive to aftermarket fluids/oils. With exception to Engine oil & Brake Fluid, I‘d stick to OEM recommendations.

Thanks..I changed out the o rings today and flushed the fluid. Noise is gone and running smooth and quiet. I did have to take the pump off as well as pulley to change the bottom o ring.
