Left just before noon to head to Nevada desert around Fallon pulling my fully loaded 26 ft. travel trailer and max cargo in the truck. Got almost up first big grade in sierras doing 654mph and truck quit running right and went into what I presume was limp mode. The coolant reservoir was bubbling. I let the truck cool down and unhookded the battery for thirty minutes and came back home. I hook my scan tool up and it showed no codes. Could old coolant cause this or did I just push it too hard.
