![]() ![]() When this happens, even though the wax solidifies, the rod is not going to return to its initial position. The rod connected to the wax cylinder of your thermostat may be dislodged. As long as it is stuck in a closed position, the coolant will not be able to flow to the engine which is going to result in your engine eventually overheating.Īnother issue that could be haunting your thermostat is dislodged rod. It could be stuck, which would result in a closed thermostat. The most common occurrence is the valve inside the thermostat is unable to open. A bad thermostat will unquestionably be unable to maintain the engine’s heat and as a result, your engine will overheat. It makes sense since the main task the thermostat performs is maintaining the engine temperature. ![]() By reading this data regarding the temperature of the coolant, the thermostat can find out the temperature of the engine.Įngine overheating is the most common bad thermostat symptom. The coolant, once it flows through the engine block, will gain in temperature by heat transfer. The car thermostat is a device that responds to the data it gets about the temperature of the engine. The only way to fully understand it is by spending some time understanding how it works. How Does A Thermostat Work?Ī thermostat is an integral part of the car’s cooling system. For this reason, once the coolant has done its job with the engine, it is going to enter the radiator so that it can be cooled down to be used when needed again. A hot coolant is not a coolant after all. Once the coolant starts to flow through the engine it is going to get heated as well. Similarly, if the engine is cold, the coolant will not flow and the heat produced by the engine will heat it up to optimal temperature. If the car’s engine is hotter than the engine temperature that the manufacturer desires, the coolant will flow through the engine until the engine gets to its optimal temperature. And this temperature is required by the engine for it to attain peak performance. Modern cars need an engine temperature between 195✯ – 220✯. The decision on whether to be in an open state or closed state is made by the thermostat and depends on the temperature of the engine. How to Fix Air Conditioner Thermostat- Effective Tips Revealed If the thermostat is closed, that means the path of the coolant to the engine is sealed off by the thermostat. An open thermostat will allow the coolant to circulate through the engine. In your car, the thermostat is a device that sits between the radiator and the engine in a car cooled by a liquid coolant. The same role is played by the thermostat in your car and its main goal is to regulate the temperature of your engine. A failed thermostat can be deadly to your engine, and if not treated promptly, it’ll affect your wallet as well.Ī definition of a thermostat is “a device that automatically regulates temperature, or that activates a device when the temperature reaches a certain point“. ![]() But in this case, the biggest problems can be caused by the smallest failures. It’s not in charge of any complicated tasks nor is it a complicated device itself. It monitors the flow of coolant through your engine, making sure you never suffer from engine overheating.Ī thermostat is a straightforward device. It always keeps an eye out for your engine’s temperature and cooling requirements. Understanding the need for a thermostat and its functioning is crucial in helping you to identify bad thermostat symptoms.Ī thermostat is the guardian angel of your engine. ![]()
