    • Works great
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.

    • Great on 2011 Honda Pilot Touring

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. ... show more

    • YMMV Might last might not
YMMV. Others have had good results from this however mine only lasted 2 days. The fit was perfect but the brush holder melted internally after 2 days of use. Sent back for a refund.

    • You may need to do some machining of the bolt hole for it to fit
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 . ... show more

    • MEASURE FIRST!
Review Image by Carrillo family Carrillo family
It appears to be working but MEASURE YOUR OLD ALTERNATOR! One other customer review mentions having to grind down the lower mount. I show the lower mount on my old alternator (2009 Honda Odyssey), it measures ~ 0.5-1.0 mm SMALLER than the alternator for sale. This item is TOO BIG! WON't FIT! Luckily I was able to grind down the lower mount lip AFTER going through the trouble of GETTING IT IN THERE. Using a dremel and a grinding stone...I am SO grateful that I didn't have to take this out. LESSON LEARNED, even if you go with some other aftermarket piece, always measure. ALWAYS MEASURE. ... show more
