The issue with the plastic expansion tank cracking has nothing to do with overheating unless it is leaking and low on water. It has a low coolant sensor that will give a warning on the dash panel.
The number one reason for overheating is a dirty radiator "if" you have a rear radiator. If you have a rear radiator and have not put a extension of 1" hose on the slobber tube back to behind the radiator you will have radiator plugging sometime soon. The fumes from the slobber tube mix with road dust and stick to the radiator fins. This is most often worse outside of the fan arc in the corners.
