Alright I'll start out with the specs of my truck it's a 05 Silverado 5.3 4x4, I was driving around the woods Saturday and the dirt road I was on started to get muddy nothing bad but enough to put a strain on the engine. Well the engine acted as if it had no power and the temp immediately started to rise up to 220-230°F. Never had this happen before and honestly don't have a clue where to start. I appreciate any input into the matter . Oh and if it makes any difference I just hit 101,000 miles.
