Where is the radiator cap for 2010 xbs? I see the reservoir tank on the left when i pop the hood but usually the radiator and cap is visible right from the get go. Sorry guys, i feel stupid for asking this question haha.

I had the same "Huh?" experience as you did.

There is no radiator cap. You refill via the reservoir tank. Coolant is good for 100k miles.

BTW this is one of the reasons I've not added a coolant gauge to my 2011 yet...too much hassle to get air out of the system and top off the special coolant...

I went through the same thing when I was going to get a TRD rad cap just to find out there wasn't one lol
