ok, so this summer i replaced my 7mgte with a jdm 7mgte, and at the time i had the head and block machined for a mhg, with the arp studs. well, after i put my new engine in, it overheats, kinda. the temp gauge says its between halfway and the red, and sometimes the overflow bottle overflows. car runs great though, there is heat, but there is the typical waterfall noise, ive burped it several times, on incline. any suggestions?
