Mitsubishi Diamante overheating issue causing car to run only 20 minutes in hot weather with clicking noise under glove box on Mitsubishi Diamante

Some Mitsubishi Diamante owners report experiencing overheating issues that cause the car to run for only 20 minutes in hot weather, often accompanied by a clicking noise under the glove box. These overheating symptoms can include smoke from under the hood and a pegged temperature gauge, which may ultimately lead to a blown head gasket. Potential causes of overheating reported by owners include coolant leaks from the water pump, radiator, or hoses, as well as radiator fan issues and thermostat malfunctions. Many owners emphasize the importance of checking coolant levels and inspecting for leaks, as low coolant can significantly contribute to overheating. Additionally, concerns with a leaking heater core have been noted, requiring extensive maintenance to repair. Radiator leaks are also a common issue that can lead to severe engine damage if not addressed promptly. Finally, some owners point out that inadequate coolant flow or insufficient air through the radiator can exacerbate overheating problems. It is crucial for owners experiencing these symptoms to diagnose and address these issues effectively to prevent further damage.
