Installed this o-ring kit on a 2009 Honda Odyssey. The steering pump was making noise and you could see bubbles in the fluid revivor when the engine was idling indicating a potential air leak from where the hoses attach to the pump. The most difficult part was finding the right 10mm wrench that would allow me to access the lower hose mounting bolt without removing the belt or pump pulley. I wound up taking an old wrench, heated it with a torch, and bent it in a vice to get the right fit. I did order a ratcheting, flex head wrench but while waiting for it to be delivered I was able to make something work. Overall, the o-ring kit worked great, the o-rings seem high quality and this fixed my issue. If you don't already have some, make sure to order the power steering fluid required for Asian/Honda vehicles when you order these o-rings.
