Will a Faulty Electronic Thermostat Affect the Car?

[StephenRose]

A malfunctioning thermostat can prevent the engine from reaching its optimal operating temperature, increasing engine wear and shortening its lifespan. Additionally, the engine oil may not achieve its ideal viscosity, leading to increased engine operation resistance and higher fuel consumption. Relevant information is as follows: Thermostat working principle: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, altering the water circulation range to regulate the cooling system's capacity and ensure the engine operates within the appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it can severely impact the engine's normal operation. Too late and too early: If the thermostat's main valve opens too late, it can cause engine overheating. If the main valve opens too early, it prolongs the engine's warm-up time, resulting in the engine running too cold.
