Perfect fit ‘07 Honda Pilot
This one seems to be the upgraded one too. I needed to change mine out as I just hit 300,000 miles and it was looking rough. Probably should have done it 100k ago but oh well. This along with new fluid and an o-ring it fixed the loud winding noise. Worth it!!

Do this before replacing the pump!
I thought I needed a new power steering pump until I watched a few YouTube videos that suggested replacing the O rings and reservoir instead. Boy! They were spot on. The whole process took less than an hour and make sure to use a vehicle specific synthetic fluid (in my case, Honda).

It’s a little off
This was a lot cheaper than the Honda brand and it came with the cap. The problem is the hose bib angles aren’t in the exact spot as the original. The tube would have been kinked if I installed it. I returned it and ordered a genuine Honda part

2008 Honda Pilot. Bought it to replace my old unit. It comes with the screen on the bottom of the unit. Perfect fit and trouble free.

Ordered a few months ago and it is doing its job. I can’t imagine this part having problems or failing in any way since it’s so simple
