Could be your coolant is boiling. Can you hear it bubbling after shutting off the engine? Get a new 18lb cap at Auto Bone. $4.99.

Year and a half isn't new. I'd start with a new cap.

you haven't addressed the poorly designed overflow port, so fluid sprays all over the inside of the engine compartment. the fix is easy.

Happens to mine every time I go offroad - I've always put it down to the bouncing around.
The first job for this weekend will be attaching a hose like the pic UnlimitedLJK04 has posted.
