Thanks for this thread, kept me from thinking I was going crazy. I agree with all of the above. I've been the only owner of my TSX and have never had a belt or pulley replaced(that I've authorized) and the stock 69.5" does not fit at all. The belt on there is the original to my knowledge. It has nothing on it anywhere to identify the maker. It's black with no writing. To the belt's credit, my TSX has 113,000 and this old belt has no cracking at all.

As for what to buy: All the listings on Rock Auto(and all other sites) for this year are 69.5" or 70". Also, the belt for the 6 cyl 3.5L is way too short (46.75" or 47")

I ordered the Dayco 7PK1715 67.5" from RockAuto. It is listed under the 2004 RSX under Belt Drive.

Here's the info: DAYCO Part # 5070675 Poly Rib Belt, Premium; Exceeds OE Specifications Effective Length 67.52 / Top Width .96 / No of Ribs 7 / Thickness 0.169
Main Drive; Type-S

Installation: To loosen the tensioner pulley use a 14mm socket and a long pipe over the socket wrench or a long handled socket wrench to get leverage and rotate the nut clockwise to loosen. You can move the coolant reservoir if it's in your way by just pulling it up and setting it out of the way in the engine compartment somewhere (there's nothing holding it in really).

My new belt appears to be the same size as the old one. It's hard to tell for sure since you're comparing a 113,000 mile stretched belt to a brand new kinked-up-from-packaging belt. I will say the new one was 100 times harder to get on than the old one. I mean really hard. I've taken the old one off and on at least 10 times trying to figure this all out and it goes on with just letting the tensioner out about 3/4 of the way.

With the new one I had the belt tensioner pushed all the way and I could just get one side over the top pulley. I then kind of rotated the belt on the pulley by pushing on the belt at the top of the pulley to rotate it clockwise, just trying to work it on. This helped me work most of the ribs onto the top pulley. To get the last rib over and get it seated right you can get as much on and then let the tension back on the pulley and onto the belt. This helped stretch it a bit and then when I let the tension off after about 10 seconds I could get the last rib over. All in all this was way harder than it should have been.

Observations: Looking at the indicator notches on the tensioner with my old belt on. It was at the far left, which I believe meant it was still on the almost too loose side. Whatever it was it was not within the normal range. Could be some stretching after 113,000 miles. With the new belt on it now is in the right range I think (hard to tell what notch means what).

Also, this TSX came from a dealer in Macon, Georgia. Interesting b/c I'm assuming BuckeyeATL's came from Georgia as well. Wonder if it had something to do with a certain shipment?

TIP: If you're having trouble getting the belt on over the top pulley, first look at the bottom two pulleys (they're both ribbed--Crankshaft Pulley and A/C Compressor) and feel and make sure the belt is seated on them both.

Second, try my recommendation of getting as much on as you can and then letting the tension back on to stretch it.

Third, send it back and find a 68" belt. I couldn't find this (why don't they just list belts by length?).

I had the same issue when I had my serpentine belt replaced as well. The belt listed is slightly too long. My indy found the correct belt although I don't have the part number. Belt was only $40 I believe. If you search "serpentine belt" there is another thread that should have the correct part number.

I am guessing the v6 is different from the 4 cylinder. Anyone know the size for a 2009 tsx v6?

Do you still have this? If so let me know and I can pay you through PayPal and give you my address. Thanks!

Could you text me some pictures of it? Is it an Acura part or aftermarket? What size belt would I use with this pulley would it be the 67.5"? Do you have a belt for this vehicle as well? I think it should be the same part for my 2012 that came off your 2009. Could you measure the dimensions of the pulley and send me that info as well? What is your phone number so that we can text back and forth? I also need your PayPal email so that I can send you the money.

Thanks,

Eric

Hate to bust your bubble, but you are asking for a part from a post that is over a year old.

There were no changes to the k24 for the life of the 2nd gen TSX. Just look up the part # on any online acura parts retailer if you need the OEM part # .. and many on this thread have confirmed the belt size.

Can you text me your info? my phone number is 503-701-1495.

Thanks!

He already responded to me stating that he still had the pulley

Fitted the bando 7pk1715 today, and as mentioned above it was way more difficult and tighter than any other belt I've replaced and tension was showing off on the assembly's tension gauge as well.
