Yeah, I know, it ain't that critical, but such a PITA.... I like everything to be as it should, you know? I lost said cap after refilling the bottle a few weeks ago (the plastic retainer strap was already broken). Even eBay isn't much help, all you can find is a whole bottle ass'y for about $39. And it isn't sold as a separate item from any Honda parts house. What other caps would fit a Fit? (pun intended). Now if someone would invent a device to keep leaves out from around the wiper shaft recesses. Makes me batty, I'm a bit OCD about that

 

You may be able to find the cap at your local junk yard.

 

Cap p/n is 38513-SB0-961

S/R $7.47

 

Thanks, I missed it on the exploded diagram, it's #1 on the list. I need to grab a couple of oil filters etc for maintenance anyway.

 

Found the thing once I took out the retaining bolts and moved the bottle. Saved a few $, don't care too much about the strap. Just got clumsy and dropped it.
