My truck over heated two times when i was moving my 18 foot Starcraft aluminium boat around the yard. it was in four wheel drive and the ground was soft. The first time it happened i got the cooling system flushed and when i moved the boat again it over heated again. i did get the truck stuck in the mud. My wife drives it to work and it has never over heated on her. the oil is clean. Any thoughts?

check to see if the fans are working then check for cold spots in radiator if you feel any thew radiator is no good. finally pressure check for leaks.
