The recommendations above are excellent, start simple and move to the bigger items. Radiator cap is cheap and can make a huge difference.

Something I wanted to add.....check your thermostat to insure it's working properly. If not it may be reading normal temps at the interior gauge when in reality your car may be overheating. Overheating can also be caused by a blocked radiator and or wrong coolant ratios or wrong coolant altogether.

Good luck.
