2003 cobra cooling issue

Yep must not of burped it correctly. It will overheat if you arent careful. My buddy made it 2 miles before his overheated

Did you burp and fill the system thru the crossover? I like to burp the system with the front end on ramps.

Could easily be that and/or the highspeed isn't coming on.
