(1) check operation of cooling fans, they should come on with AC on. Check they are coming on when engine gets hot. (2) Flush out and check the flow in your radiator (http://www.howacarworks.com/cooling-systems/how-to-flush-an-engine-radiator), (3) check water pump for flow, squeeze upper rad hose when engine is hot (and thermostat is open), it should have coolant flowing under pressure to radiator. If not water pump may be worn, even if it isn't leaking.
