Welcome to 2CarPros.
Does the vehicle actually overheat? Have you confirmed accessory drive belts are tight and nothing is slipping? All of the things you mentioned can be related to the accessory drive belt. If the belt slips, you could lose power assist to the steering, voltage from the alternator which will affect the vehicle's electronics, and overheating.
Check that first and let me know what you find.
