Howdy! I would bet on the fan clutch being the problem. It may appear to be working, but at high temps it should not slip at all, keeping the fan at full speed. When you shut off the engine when it is reading 240 at the sender, can you turn the fan with one finger? To me that would indicate that it is not locking up for max cooling. John
