i don't see any reason why you couldn't run a 190 t-stat. i have a 180 in mine and motor runs at 190-195, i don't think the fans coming on at 213 is where you want to be, i would try to be at 195-200 with the fans. personally i don't like to see my motor getting above 200-205. i don't run an
oil cooler so my
oil temps are probably at 210-220.
