EOT and ECT temp questions
ok so Im pretty new to the 6.0. This weekend we took the excursion up to winterpark from colorado springs. The way up we had a nice 50-60mph head wind so the drive sucked... My question is driving my EOT/ECT temps run anywhere between 8-11 degrees different, but on the long uphills really working the truck i was getting 15-17 degree difference but soon as we got onto level ground the temps went back to the 8-11 degree difference.. now the trip home on the same hills without the nice head wind the temps were anywhere between 8-12 degrees. My question is when your really loading the engine the temps go up and hit the 15+ degree difference mark, does this mean my cooler is going bad? we have a full gauges plus the bullydog monitor thing, but we dont run the tune, we just leave it stock..
