<div><p>A thermostat with a lower opening temperature does not prevent overheating. It may buy you some time before the engine overheats but if you are long enough in a traffic jam it will overheat eventually. A more powerful fixed fan may alleviate the problem a bit but the only real solution will be a properly installed electric fan.<br></p><p>I have done this from the sixties on all my cars that had a fixed fan.
