Works. Hope it lasts a long time. I had to grind down a bushing on the alternator in order for the lower bolt arm to fit in its slot on the engine. I probably took a full 1/16 inch off with the bench grinder. The alternator I replaced also had the same place ground down! I guess this isn’t the first time it’s been replaced. 205k miles and ticking on this 2011 Honda Pilot.

Fits Odyssey 2010. Make sure the spacer at the mount point is pushed back or it won't fit. Other than that, worked like a charm.

The media could not be loaded. Do not buy this, went out after 4 months and I can't even return it or swap it out for another one.

Works excellent. 2010 Honda odyssey is notorious for its degree of difficulty in alternator replacement. But this part does fit . I suspect because it fits many different models and brands is the reason for the bolt hole discrepancy. If you are replacing this at home and the bolt is not fitting through correctly. DO NOT WORRY You have the right part , head down to a machining shop or auto parts store and get it enlarged. It will take you less than 20 minutes. If you have the tools to do it yourself; Alhamdulillah, just grind the opening a little bit and it will fit right in .

Still holding up after a year's use. Not noisy and seem to work well with my battery.

Fit great on 2011 Honda Pilot Touring. Had to smack the grommet thing on the larger bolts hole as it was out abit just but it had a bit of gap in it to be smacked. Also the nut on the that goes under the washer type connection (then you put another nut on top) was too tall so I reused the stock one. Other then them things charges great and all connections were snug and plugged in exactly how they should.

Works like expected. The install stumped me a little as I had to slide the bushing back in the engine mount to fit the new alternator.
