There are a couple other threads about the serpentine belt and which size/model to use.

The conclusion seems to be most websites list the size of our belt incorrectly. They say it is 69.5", which it is not, at least for my car and I know one other thread came to the same conclusion. I had purchased the Bando belt (69.5") and it was long enough that I was able to install the belt by slipping it right over the tensioner without having released it. I measured the OEM belt at 67.5", which is the conclusion of the other thread. Again, that was the original belt and I do not have aftermarket or undersized pulleys.

The correct Bando part number is 7PK1715, for the i4 engine.

I own a 2009 TSX A/T Base. If your experience differs from mine, please let us know. Share the information of your TSX as well.

I used a Dayco 5070675DR on my 09 6mt. I believe that crosses with the Bando part number you posted

I just changed the serpentine belt on my 2010 TSX Base 4cyl using the Bando 7PK1715 67.5 in. belt. Exact same size as the one being removed.
The one being removed (original) had 186K miles and still looked pretty good. Took about 20 minutes with help from my son.

Glad to hear! My belt was ~108xxx miles old. I think the EPDM rubber they use now does not show cracks, but the tread still wears down. Better to replace than lose a belt!

I want to let everyone know that I ran into some issues with the longevity of the bando belt.

The OEM belt has better fitment and the textures of the two seem to be different. I'd also recommend cleaning your pulleys when you swap the belts.

Where did you buy the OEM belt?
