What are the differences between these radiators: 19010-P73-A02 and 19010-P73-A03

I'll post pics of the cap but it wasn't a Honda cap. I was surprised the OEM cap wouldn't work. The TYC was about $50 so I opted for the OEM look and cheaper price.

I posted on the ht thread but try the other Honda cap . There’s two.

Top two pics are the OEM radiator and cap.  Bottom two pics are the TYC 2028 radiator and an aftermarket cap.  I was surprised that the OEM-like TYC needed a different cap.

The cap I posted a picture looks like it should work. It was on the 7th gen accord and a few other hondas

Nice bike op ! Try the other cap style. I had the same on another radiator. They like the new bigger thread version on the radiators lately. Probably cost and tooling.

Have you tried the other cap yet sir?

I only have that cap that's on the TYC right now. I can't quite make out the part number on the pic on page 3 but the part number for the 6th generation Civic radiator cap is 19045-PAA-A01 but it doesn't seem to match the part of the label I can see. The current cap on the TYC seems fine. I drove 60 miles on the freeway in 102 degree heat with some hills as well as traffic while the AC was running and the caR didn't overheat.
