What would cause overheating in bumper to bumper traffic or frequent starts and idling due to heavy inner city traffic. The thermostat, surge tank, radiator, and water pump have all been changed.(it is a 2000 Chevrolet Malibu)

Answers from the Automotive Experts

Patty Streeter,  at AskPatty.com Overheating can be caused by anything that decreases the cooling system's ability to absorb, transport and dissipate heat: A low coolant level, loss of coolant (through internal or external leaks), poor heat conductivity inside the engine because of accumulated deposits in the water jackets, a defective thermostat that doesn't open, poor airflow through the radiator, a slipping fan clutch, an inoperative electric cooling fan, a collapsed lower radiator hose, an eroded or loose water pump impeller, or even a defective radiator cap.
