my truck decided to jump up to 230 deg today under normal driving, usually runs 190ish -200 max if i am pushing it without a load... so 230 scared the chit out of me for a minute...stopped at the house before heading to get the kids, put some cool water in the radiator and it dropped to 190 again.. and stayed there..but after more looking the radiator may have been just a tad low, nothing crazy.. but i did notice that it didn't look like it was circulating in the radiator.. now it had cooled back down to under 190, so my question is will it not circulate if the t-stat isn't open?
