Mitsubishi Lancer temperature gauge reading hot intermittently despite replaced thermostat and water pump on Mitsubishi Lancer

Some Mitsubishi Lancer owners report experiencing intermittent high temperature gauge readings even after replacing the thermostat and water pump. These issues may stem from a faulty radiator fan, which can cause the engine to overheat, particularly in traffic. Additionally, a defective coolant temperature sensor may provide inaccurate readings, leading to fluctuating gauge indications. Some owners also find that air trapped in the cooling system contributes to these temperature fluctuations. Furthermore, a malfunctioning temperature gauge itself could be responsible for the inconsistent high readings. Addressing these potential factors is crucial for accurately diagnosing and resolving the temperature gauge issue.
