mines the same way but comes and goes like a air bubble but i have fixed it over and over, so im wondering if a in hole in a heater hose would suck inair while cooling off... but i heard if you ground out the wire going to the sensor on the top of the radiator it willnever come back but thats if you can check your coolant every other day or so..

burp the hoses, speeze both of them at the same time. That ussually gets a decent amount of air out. Also, try running it with the cap off until it gets hot enough to start expanding the coolant to make it overflow. Might just have an air bubble in it. These are a bit more difficult than other cars to bleed the air out. Good luck!!!
