How does the Antifreeze look? Might need to flush the cooling system, Maybe a weak water pump?

also check the operation of your fan and fan clutch

This is probably going to be an airflow problem. Check the fan clutch for proper operation and check the front of the radiator and air- conditioning condenser for dirt or any obstruction. HTH. -Jim
