Overheating can be caused by the thermostat, plugged radiator or a faulty headgasket. On the Saturn S-Series, overheating is more commonly caused by a missing air dam (if you mostly drive in town), or a failed cooling fan.
It's the current flowing in a wire that causes it to overheat.

If the Chevy Celebrity radiator is smaller that the Saturn radiator it might well overheat from not enough cooling capacity. If the Chevy Celebrity radiator is the same size or larger than the Saturn radiator I would think it would not over heat.

Saturn does have seasons, each of them lasting over nine years. The thickness of Saturn's rings though hard to see at times show what season the ringed planet is in. It takes 29 years for Saturn to complete its journey around the Sun. As Saturn moves along its orbit, first one hemisphere, then the other is tilted towards the Sun. This change causes seasons on Saturn, just as the Earth's tilt causes seasons on our planet. This allows Saturn to experience the same four seasons.
