New cooler installed in April of 19 , plugged again in first month. Ford will not touch it without a code regardless of temp deltas. 10 deg at idle once warm 30 deg 5 miles of highway pushed her up to 260.5 deg and still nothing. Patriot tuner, could the parameters be way out in it not allowing the truck code as it should? This is a 911 , not wanting to melt her down but nothing has worked so far. Just returned truck last night hoping that would reset but had 30+ split driving his morning still nothing. Any help much appreciated.
