Hi, I just bought a 580K, and Im trying to ID what this cap is called so I can buy a new one, Ive run a 310J for a while but this is my first Case, waiting on a user manual or else I'd have already looked it up. The cap in the red circle is broken, and as far as I could tell it looks like the cap for the coolant tank, but when I go and type in case 580k coolant cap I get results for the cap at the top of the radiator that I circled in blue. Any help would be great, the reserve that the cap circled in red is attached to is empty so Im making an estimated guess that it is the coolant and it all sloshed out with the missing cap

Please help...

I didn't find the right solution from the Internet.
