What are the symptoms of a faulty thermostat?
1 Answers
The symptoms of a faulty thermostat are: 1. If the thermostat fails to open, the temperature gauge will show the coolant temperature in the high-temperature zone, but the radiator fan won't turn on, the engine temperature will be high, and it's prone to losing antifreeze; 2. If the thermostat fails to close, the coolant temperature will rise slowly, especially in winter where it may stay in the low-temperature zone for 10 to 20 minutes, and the idle speed will be high. A thermostat is an automatic temperature-regulating device, usually containing a temperature-sensitive component that opens or closes the flow of coolant through expansion or contraction. It automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the circulation range of the coolant to regulate the cooling system's heat dissipation capacity.
